I referred to this site when I was doing my research. But with any internet source, you should take it with a grain of salt. It just so happens that my results were similar to theirs, I am not saying it is the end all test.

LensTip later did a supplemental test, where the Hoya HD (and a few other filters) were tested:

HOYA HD or B+W MRC?

Those two earned the same score on optical testing:

so why not go for the tougher one (to help you sleep better)?

is 20$ normal for a good filter or would i be looking to spend 40$ on http://www.bhphotovide​o.com …007_Protection_​Clear.html (external link) so how do you know if you need (i guess i could say get away with...)the cheaper or the more expensive HD/MRC filters?

also the slim version is even more at 53$ (http://www.bhphotovide​o.com …lear_Multi_Resi​stant.html (external link)). is the SLIM versions used for wide angels only? (id have to get a SLIM 77mm UV filter so there is no vignetting/blurring on the outsides of the image, correct?) and a normal standard filter (non slim) is the "norm" for a 50mm 85mm 75-300mm etc?

If you are going to use a filter at all, you should use a multi-coated filter to minimize image degradation from glare/internal reflections.

The cheaper (non-multi-coated) B+W filter can definitely lead to image degradation (take a look at the 2 flare tests -- the "with filter" shots definitely had worse flares):
http://www.lenstip.com …B+W_72mm_010_UV​-Haze.html (external link)

The B+W MRC is definitely much better in that regard (hardly any difference between the "with filter" and "without filter" shots in the flare tests):
http://www.lenstip.com …2mm_010M_UV-Haze_MRC.html (external link)

Hoya Pro 1 Digital and Hoya HD are quite good as well (the HD tested equally well as the B+W MRC, while the Pro 1 Digital tested even better than the B+W MRC):
Ranking: http://www.lenstip.com …_results_and_su​mmary.html (external link)
Hoya Pro 1 Digital: http://www.lenstip.com …Pro1_Digital_MC​_UV-0.html (external link)
Hoya HD: http://www.lenstip.com …ent_Hoya_HD_UV_​67_mm.html (external link)

B+W tends to be more expensive than equivalent Hoya products, but not offering more (at least according to the LensTip testing shown above).

Most "slim" filters out there do NOT have front filter threads. That means you won't be able to put normal lens caps on over the filters, so after each shooting you need to unscrew the filter, put the lens cap on the naked lens, then put the filter away in a filter wallet. Cumbersome to say the least.

Hoya Pro 1 Digital filters are thin enough to not vignette, yet still have front filter threads to allow use of conventional lens caps. I think the Hoya HD are equally thin.


:cool:

(I don't get kickbacks or commission from Hoya, I swear.)  :p

i like the digital pro 1 hoya and the fact it is better then the HD and MRC and it lets you pop the protection cap on over the filter so you never have to take it off.

http://www.2filter.com …s/B+WUVcamerafi​lters.html (external link) B+W MRC is 37$ at 52mm (for a 50mm 1.8) and the 77mm (for 10-22) is 63$

what is the difference in filters? one says UV the other clear...they not the same thing what would i need im guessing the UV correct the one for 37$ and not 32$ (sorry for all these questions, just would like to not buy the wrong one if they have a million options on the website)

http://www.bhphotovide​o.com …2_mm_Ultraviole​t_UV_.html (external link)
Hoya Digital Pro 1 is 32$ or 37$ at 52mm and 72mm is 52$

someone from this site recommended the 2filter,com for cheap filters. reputable seller?

thank you for taking the time for all the link and information i greatly appreciate it!

The Hoya HD has the same thickness as Pro 1 Digital (ie. won't vignette) and also has front filter threads:

Like I said previously, Hoya filters are cheaper than the equivalent B+W filters, yet perform equally or better on testing.

Back in the film days, UV filters did more than protect the front element -- excessive UV light can cause fogging of film, so UV filters theoretically improve colour saturation in photos.

However, digital sensors already have built-in low-pass filter to block out UV light, so UV filters will do nothing more than clear glass filters. If your main purpose for getting the filters is to protect the front element of the lenses, a clear glass filter will do just as well, so save yourself a few dollars.

Never dealt with them -- to save on international shipping, I usually order accessories like filters and batteries at the same time as big-ticket purchases like lenses, which I only buy from B&H and Adorama.

Maybe other POTNers will chime in.

Good luck with your purchase.
