Filters - Help!

[bornshooter]

haha I just needed to comment on the "no filters" remark . . . .

try taking a long exposure of the ocean or a landscape with a brighter sky than the foreground, and see what hapopens to the sky! To combat that, you would have to create multiple exposures and then combine themm in PS. Instead, using a gradient filter for the sky of 1-2 stops, which you can even handhold flush in front of the lens, will allow you to do all that work with one click of the shutter. It's the "in camera" way to do things professionally for quality results. HDR is a whole other matter usingt multiple exposures and then working in post with the settings you want to achiewve a certain look . . . hopefully it's not that new "pro photographer/artist," pastel, oversaturated look

UV filter no unless in a bad enviroment.polarisers, nd, nd grads, yeah for sure

Does anyone have issues with vignetting on a 24-105 with an B+W 77mm MRC UV 010 F-Pro?

No issues there. My test results below (click for details) show that you don't see an increase in optical vignetting until you stack two F-Pro filters on a 24-105mm.

I forgot to mention that these shots were taken with a 60D, which has a crop sensor. A FF camera may have vignetting not evident in my shots.

It's really hard to get an EF lens to vignette on an APS-C camera...

...the Canon OEM Ultrasonic lens cap fits but there there is a 1mm gap between the filter and the lens cap.
Have any of you had any issues with caps falling off of XS-Pro filters in the past?

I don't find the gap to be an issue - I've never had a lens cap knocked off because of it. Sorry I didn't mention the gap previously, didn't think it was an issue. The gap I see is less than 1mm, maybe 0.75mm - and in fact, when I look it seems there's a small gap with the F-pro mount, too (not quite as wide). Here's what I mean (77mm filters and a Canon 77mm Ultrasonic cap):

Neuro, thank you!

As usual, you are a mountain of information! The gap is indeed .75mm or so and I only tried the cap on the filter thus far, I have not even mounted them on the lens yet. I got a deal on three XS-Pro filters and F-Pro's were not an option from this seller.

My Hoya Pro1 UV, which is equally as slim as the XS-Pro's, allow the Canon caps to fit snug - which is what prompted my post about the gap in the first place. I will mount them with confidence that I likely won't loose the caps.
