Best camera lens sky & uv filters according to redditors

You'd need a lens that blocks all but UV. (one I found; http://www.amazon.com/Black-Glass-Filter-Violet-Transmission/dp/B0012C5L4K/ref=sr_1_1?ie=UTF8&qid=1407972342&sr=8-1&keywords=uv+pass+filter )

and a modified dslr. I modified one of my Nikon D70 cameras for shooting in IR, this is a similar thing, but a different end of the spectrum.

Also you'll notice nearly everyone was shot in direct sunlight, which you'd /NEED/ to get the exposure up enough for video.

Here is UVA tranmission filter. You may need to use a UVA light source as a flash since the glass in your camera will absorb a bunch of the light.

This is from Jack Perry Park. I had just got the ND filter in the mail and had to test it out. amazon https://www.amazon.com/67mm-3-0-1-000X-Single-Coating/dp/B00485XSQ6

   Oh boy this is gonna be fun. (Also I'm half asleep right now so this is gonna be even worse than my normal worststories, just warning you!)
   
   

   
   <br />
   &quot;I'm telling you, there's something going on with these guys,&quot; whispered the worlds greatest spy, Jimmy Link into his secret microphone as he infiltrated the seemingly innocent garden store by pretending to be a customer. &quot;I just can't figure out what.&quot; <br />
   <br />
   &quot;Take as many pictures as you can and I'll have a look at them,&quot; urged his boss, L, listening to his call from MP3 headquarters. &quot;Use those camera filters I gave you.&quot;<br />
   <br />
   &quot;Roger that,&quot; muttered Link. He pulled out his camera and started taking photos. To the untrained eye, the filters he used on his camera appeared to be a normal 3 Piece High Definition 52mm Filter SET with Protective Case for NIKON D5500, D5300, D5200, D750, D7200, D7100, D7000, D5100, D810, D810A, D800, D610, D600, D3300, D3200, D3100, 1 V1, D4, D4S, D3, D3X, D3S DSLR Cameras. However, secretly they had XRays and stuff.<br />
   <br />
   &quot;Are you getting anything?&quot; Jimmy asked. <br />
   <br />
   &quot;No... wait, yes! Take another photo of that guy reading the book!&quot;<br />
   <br />
   &quot;Which guy? There are five people reading books here.&quot;<br />
   <br />
   &quot;The one reading 'What Great Brands Do: The Seven Brand-Building Principles that Separate the Best from the Rest'.&quot; Link saw him immediately and zoomed in with the camera. *CLICK*. <br />
   <br />
   &quot;Ok Jimmy, the X ray filter shows up that he's got a gun. Take pictures of him with the other filters, I'm intererested to see if he has anything else.&quot; Jimmy obliged. *CLICK.* The man stood up, looking angry.<br />
   <br />
   &quot;Hey, quit taking photos of me!&quot; He yelled. <br />
   <br />
   &quot;Shit, I think he's onto me,&quot; muttered Jimmy. <br />
   <br />
   &quot;Hey,&quot; L jabbered in his ear. &quot;You're in trouble. He's got an alarm button in his sleeve and he's pressing it. He's probably summoning reinforcements, you'd better get out of there! And...&quot; Sure enough, seconds later lots of men in black suits appeared and began converging on Jimmy.<br />
   <br />
   &quot;Too late. I'm going to have to fight.&quot; Jimmy disconnected his headpiece before L could object. He cracked his knuckles.<br />
   <br />
   &quot;Evening, gentlemen.&quot; The men pulled out guns and started to shoot.<br />
   <br />
   Jimmy ran really fast, he ran so fast he dodged all the bullets. Several of the men ended up shooting eachother in the crossfire because they missed because Jimmy was running so fast. He ran up to the surviving men and punched them in the face so hard their heads exploded. But still more men came.<br />
   <br />
   In desperation, he began to climb up a wall which was covered in vines, because *obviously* every good garden centre has a wall covered in vines which are strong enough to climb on. Miraculously avoiding all the shots the men were taking at him, of course. He grabbed onto a vine dangling from the ceiling and swang. His aim was perfect (of course) and the vine swang neatly around several of his assailants, tying them together. He let go of the vine and flew feet first into another group of assassins, knocking them to the ground. <br />
   <br />
   Sure that he'd got everyone, he stood up and brushed the dust off his suit. But just as he reconnected his headpiece, more men burst through the doors.<br />
   <br />
   &quot;L. I'm in trouble. I need help,&quot; he snapped.<br />
   <br />
   &quot;Why did you turn your headset off? I was going to help you! Anyway. Get under cover, quick. I've hacked their system, and in a minute they're going to get a very nasty surprise. Just stay away from those Gardena 1949 7-Setting Circular Sprinklers Vario With Spikes that are there to water the plants.&quot; Jimmy nodded and dived into a fountain. <br />
   <br />
   Just in time. All of a sudden all the sprinklers started squirting water everywhere. But it wasn't water! As the liquid landed on the men in suits they started screaming as their suits and flesh began dissolving into a bloody mess. <br />
   <br />
   &quot;What did you do?&quot; Asked Jimmy, amongst the chorus of &quot;OH GOD IT BURNS&quot; and &quot;MY EYES!&quot;<br />
   <br />
   &quot;I hacked into their mainframe and doxxed the code for their hard drive to reverse the polarity of their firewall and basically DDOS'd the server so they couldn't reinstate their motherboard and long story short made the sprinklers spray acid instead of water,&quot; explained L helpfully. &quot;Because I am a computer expert and this is how computers work, trust me. You can tell because of how loudly I'm typing.&quot; Sure enough, Jimmy could hear loud, frantic typing at the other end of the phone.<br />
   <br />
   &quot;Good. Anyway I'm going in. Wish me luck,&quot; Jimmy said.<br />
   <br />
   Some time later, Jimmy had reached the inner sanctum of the evil lair disguised as a gardening centre. Along the way he had avoided countless traps and killed loads of bad guys. However barring his way now was a huge metal door. He'd tried to punch it open but he'd only managed to bruise his fist.<br />
   <br />
   &quot;What now?&quot; He asked L, frustrated.<br />
   <br />
   &quot;That gum I gave you. You know, the Grenades, Explosively Intense Sugar Free Chewing Gum, 30 Pieces (Atomic Peppermint).&quot;<br />
   <br />
   &quot;What about it? I don't feel like a snack.&quot;<br />
   <br />
   &quot;Have one. Make sure you stop chewing after 10 seconds, and then stick it in the keyhole of the door and run like hell.&quot; Jimmy looked at the name of the chewing gum and recoiled.<br />
   <br />
   &quot;Please don't tell me this does what I think it does. I am *not* putting explosives in my mouth, let alone *chewing* them.&quot;<br />
   <br />
   &quot;You have no choice I'm afraid. They're saliva activated.&quot;<br />
   <br />
   &quot;Can't I just...&quot; Jimmy stuck out his tongue and licked a stick of gum. &quot;THere. That should work, right?&quot; <br />
   <br />
   &quot;DON'T JUST STAND THERE HOLDING IT LIKE AN IDIOT,&quot; Screeched L. &quot;STICK IT IN THE LOCK AND RUN!&quot; Jimmy realised his mistake and stuck the gum in the lock before turning and throwing himself to the floor, just in the nick of time. There was a deafening bang and a white flash. When Jimmy picked himself off the floor he realised his clothes had been burnt clean off him (yet amazingly he was somehow ok). There was no trace of the metal door, just a small mushroom cloud and metal shrapnel which had conveniently not hit him.<br />
   <br />
   &quot;Wait... L, when that gum said *atomic* peppermint, it didn't mean... actually... you know, *atomic*, did it?&quot; L was silent. <br />
   <br />
   &quot;L... did I JUST SET OFF A MINI ATOMIC BOMB JUST TO GET IN THIS DOOR?!&quot; Yelled Jimmy.<br />
   <br />
   &quot;Yeahhh... about that. You're gonna need to be treated for radiation poisoning when you get back, ha ha. Also you're probably gonna die.&quot;<br />
   <br />
   After Jimmy had spent a solid ten minutes swearing at L and promising to murder him painfully, he decided to just get on with it and go confront the bad guy before he dropped dead from the radiation. <br />
   <br />
   &quot;Well well well. Mr Link. I have been expecting you,&quot; said the bad guy as he spun around in his chair, stroking a white puppy. He recoiled as he saw Jimmy. &quot;What the heck. Why are you naked?&quot;<br />
   <br />
   &quot;Jimmy, don't forget your DURAGADGET Black Water-Resistant Neoprene Carry Case for Wacom Intuos 'Art' | 'Draw' | 'Photo' | 'Comic' Pen and Touch Graphics Tablets - Now with BONUS 2-Finger Artist Drawing Glove!&quot; Hissed L in his ear.<br />
   <br />
   &quot;What?&quot; Whispered Jimmy.<br />
   <br />
   &quot;The glove has-&quot;<br />
   <br />
   &quot;Oh no wait, I see what you mean!&quot; Jimmy pulled the glove and drawing tablet case out of his bag and pulled the glove on threateningly, even though he really didn't have a clue what he was doing. The villain smirked evilly and pulled out a laser gun and fired it.<br />
   <br />
   Jimmy squeaked and instinctively protected his crotch with the drawing tablet case. And it was a good job he did because the laser beam bounced off the case and started ricocheting around the room wildly. The bad guy screamed and dived to the floor, and Jimmy suddenly saw his chance. <br />
   <br />
   &quot;Well,&quot; he said, pulling out a stick of gum and licking it. &quot;It's been a *blast* meeting you.&quot; He dropped the gum and walked out, ignoring the explosion behind him.<br />
   <br />
   &quot;THat's not what I intended for you to do with the tablet case!&quot; Snapped L.<br />
   <br />
   &quot;I don't care! You literally gave me radiation poisoning!&quot; Growled Jimmy. &quot;I really couldn't care less!&quot;<br />
   <br />
   Then he dropped dead of radiation poisoning. 

Hoya is a popular favorite for high quality but often at a decent price, which as a newbie is what you'd probably shoot for. Zeikos is generally considered low quality, but as a newbie you might not notice. First-party filters aren't bought very often.

If your camera came with the kit 18-55 then you probably have a 58mm filter size (as in the tip is 58mm wide). You can confirm this by looking for a spot on your camera that says ø58 in which case this filter should work fine for you. If that's too expensive then this one should still be decent quality.

But honestly, my suggestion is don't bother. You're not going to smear chocolate on your lens, and if you did the worst that would happen is you'd have to wipe it up. Just don't be dumb with your new equipment and everything will be fine.

He does say what it is. It is a UV filter.

The camera and lenses are awesome value.

I would ignore the accessories from your calculation though, especially if you're trying to resell. Most are no name / low quality. They probably work fine but will be a lot harder to resell.

Think Amazon Basics (https://www.amazon.com/AmazonBasics-UV-Protection-Lens-Filter/dp/B00XNMXE82/ref=pd_lpo_421_bs_lp_t_2?_encoding=UTF8&psc=1&refRID=DWYJ3KWBXKWTPRAK8YZB)

vs. "brand name" (https://www.amazon.com/Kaesemann-Circular-Polarizer-Multi-Resistant-Coating/dp/B00OK6YSAS/ref=pd_bxgy_421_img_2?_encoding=UTF8&pd_rd_i=B00OK6YSAS&pd_rd_r=DWYJ3KWBXKWTPRAK8YZB&pd_rd_w=vP3OQ&pd_rd_wg=dx1nu&psc=1&refRID=DWYJ3KWBXKWTPRAK8YZB)

Yeah, I feel ya. Maybe it's just me, but I feel like talking about technique and composition is harder in-person, so I tend to fall into the gear talk more easily. Some of that stuff just becomes so automatic that it's hard to verbalize even when you're looking right at it. It's almost like the photographers need to do a debrief with laptops and beer to figure out what worked well the night after a game. I'd be way better at breaking down what I was thinking after a shoot than during--same goes for hearing and processing what the other photogs were working on.


Those tight shots are what I got comfortable with and stuck to for a long time. I knew they worked, so I stuck to them for a very long time. What I like to do now is get the tight shots early and make sure I have a good set of winners that I'd be happy to post. Then, I start playing around and experimenting. I definitely get more trash than keepers that way, but the keepers are so much more interesting. Forcing myself to use a wide lens (24mm on a full frame) and embedding myself within a squad also helped. It really helps to get more environmental when you can't get close, you don't really have a choice.


I like Hoya filters for burners. They're great glass at a super low price: https://www.amazon.com/Hoya-Digital-Frame-Multi-Coated-Filter/dp/B002L60TTI/ref=sr_1_3?ie=UTF8&qid=1526067968&sr=8-3&keywords=hoya+77mm+uv+filter

I like my B+W ND 3.0 filter. I used it to make this picture a while back. Has minimal color cast and only cost me $60. I love the idea of Lee filters but they're just too far out of my price range at the moment. I actually find myself using my ND 1.8 more often than my ND 3.0, but they both get the job done. There is a slight tint, but it's easy to fix in post. I don't think any ND 3.0 filters are going to be free of color cast no matter your price range. Not sure if buying the multicoat version would help that at all, but I don't think it'd be worth it for $40 more.

I have the B+W I bought after seeing it recommended in another thread and have no regrets. B+W 67mm ND 3.0-1,000X with Single Coating (110) https://www.amazon.com/dp/B00485XSQ6/

I had the same problem trying to use a my filter from my X100 I ended up getting a thinner filter and it solved my problem.

Will this be sufficient for this use? Any recommendation other assessories that would be helpful?

The Nikon NC 52mm filter is hard to beat for $23.

anniversary
I want this for my camera

How about they are at the library, in the darkest corner in a section no one ever goes near and they are huddled and discussing excitedly but whispering...you would want to have a snoot on your strobe so everything around them is dark...

SCENE There's one thats a bit more than $5 in the used section...

Will a polarized lens do the same?

Sold! https://www.amazon.com/58mm-Infrared-UltraViolet-Blocking-Filter/dp/B00A87Y4EI

Well, sheeeeeeit -- I really appreciate you telling me this, so I don't waste any more energy. Que sera sera! That's for the info about the BK7 and your experience with the Baader filter -- you got a 52mm screw on like this one?

This one https://www.amazon.com/gp/product/B00485XSQ6/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 and a adaptor to my sigma 19mm (46mm thread)

Im a noob at this, and just purchased all my gear over the last few weeks here. Its arriving by May 6th, so what are some things I should know about long exposure photography?

Gear:

ND Filter: BW 10 stop Filter

Tripod: Amazon Basic 60 inch

Shutter release: Neewar DSLR Shutter release

I need a sanity check. I got a sweet deal on a 50mm f/1.4 lens for my Canon Rebel t7i, but upon receiving, I realize the lens doesn't fit. I've been reading the lens compatibility and even tried http://lenshero.com/ but I am still lost.

I grabbed this lens, and after poking around a bit, I think I need this filter? I can't be sure as I don't know if I am understanding the compatibility right.

This is what I bought:

PolarPro DJI Mavic Air Filters - Vivid Collection - Cinema Series - Neutral Density Polarizer (ND/PL) Filter 3-Pack https://www.amazon.com/dp/B079C3BGFC/ref=cm_sw_r_cp_api_i_pAydBbV7FWYEA

Your sensor is more sensitive than film, to uv light.
With daylight film, UV would cause slight "haze" problems.
With digital it picks up UV more so the manufacturers had to place a UV filter in front of it.

See this link to see what a sensor without a filter looks like.
http://www.lifepixel.com/digital-infrared/samples11.htm

Even a good filter, like the Nikon NC (neutral colour) filter has reflectivity problems with digital if you have a bright subject in the shot:
http://www.amazon.com/gp/customer-media/product-gallery/B00009R96C/ref=cm_ciu_pdp_images_2?ie=UTF8&index=2

A basic UV filter, cheap ones can add funny flair, but they can be removed quickly and easily. If I take the filter off I generally make sure to use a lens hood.

I agree with oldscotch. This lens is great and easy to use. It also encourages to move your feet more to get the right angle rather than rely on zoom. I ended up using this a lot more than the 18-55 5.6 kit lens when I started off cause it was just more fun. Also, the price is pretty good:

http://www.amazon.com/Nikon-35mm-1-8G-Digital-Cameras/dp/B001S2PPT0/ref=sr_1_1?ie=UTF8&qid=1334116656&sr=8-1

Usually it's $199 so I'd just wait a few days until they get more.

Another thing I would buy just starting off is some sort of filter for your lens. I'll probably get yelled at for saying this here but its a great way to protect one of the most expensive parts of your kit. The filter will break and not the lens. When you start off you most likely wont even see the difference between having the filter on or not:

I originally bought this one because it was so cheap

I've bought this one for my other lenses

Is there some reason I shouldn't? They are very clear and multi-coated. I don't feel that they take away from my image quality.

Promaster Digital HGX Ultraviolet (UV) Filter - 67 https://www.amazon.com/dp/B002694NGA/ref=cm_sw_r_cp_api_i_5lUJDbDF3KFRF

It’s the HGX Ultraviolet

This camera is fantastic at both photos and videos, and this refurbished model saves you more money for a great lens, which is by far the most important part of your investment.

This incredible lens has recently had a big price reduction. It has pro features such as a fast, constant aperture and stabilization that will make it possible to shoot sharp photos and videos even in low light, where most lenses fail. It shoots everything from landscapes to portraits perfectly. You will likely keep this lens forever, and it is an ideal lens to learn on. Much better than the cheap kit lenses bundled with most cameras that are very limiting.

I think I use this one just for when its bright out. works pretty well.

You need a 52mm filter. Going with Hoya tends to be a safe choice. UV filter is ok. Something like this. https://www.amazon.co.uk/Hoya-52mm-Digital-Screw-Filter/dp/B002L72ANK/ref=sr_1_1?s=electronics&ie=UTF8&qid=1519040015&sr=1-1&keywords=hoya+52mm

That one? If you could point me towards one I'd appreciate it.

My lens takes a 40.5 mm filter, but the same seller also carries other sizes, like 49mm.

If neither of these fit your lens, your best bet would be finding the size you need and searching "XXmm UV filter." If you can't find the size, you could also search "[e pz 16-50mm f3.5-5.6 oss] UV filter."

Not sure why you’re saying that mounting a UV filter will triple your surface area for Dew forming. If you attach and seal your circular filter appropriately you shouldn’t be getting dew formation between the lens and the inside of the filter (attach it when you’re not in a humid environment?).

Also strictly speaking, you’re actually going to be reducing the surface area that dew can form on since lenses are typically curved on the outer most element, whereas a filter will be flat. #math

And then, if it’s going to be a dewy environment, it’s going to form on the glass regardless of if you have a filter on it or not. In fact, if you get a filter with a special coating, you might even be able to decrease the incidence of dew formation.

Regarding artifacts: Rare. You’ll get them when you’re at strange angles to your light source and/or if it’s a very poor quality uncoated filter. And even if they do show up, it’s trivial to remove such artifacts in post.

Finally cost/quality? A filter with decent coatings will typically be under $100. So you are saving money by not having to buy another $100 lens. Your argument about cost literally makes no sense. A good enough filter will always be cheaper than the lens, so you are still saving money.

So honestly, you really should have used a UV or general protection filter.

e.g. Hoya Evo Antistatic UV Filter - 77mm - Dust / Stain / Water Repellent, Low-Profile Filter Frame — $75

That being said, I really like your photos—they are quite cool.

Edit: source regarding filters and dew.. I’ve done a lot of outdoor and early morning landscape/Astro shoots for fun in a variety of climates including humid ones.
