Okay guys n gals, this has no doubt been done to death but I have to ask -

Using a Hoya ProV 1 UV filter on my 70-400G - Will it effect the sharpness especially at 400mm?

Tempted to just take it off as I always have the hood on the lens but there is that nagging little voice that says "if you scratch / break it your screwed"

So - any of you tried it and did you notice any difference?

My experience with UV filter is it don't effect my image quality or sharpness regardless i use or not use the filter. I use cheap ebay filter as well so is not any decent stuff like hoya.

My only problem with filter is at night time or reflection with light source during dim environment because I will get that horrible green glare on the image ......... when i take the filter off the glare is gone, so my lesson learnt was to check my image first before proceeding ........

My mate's image is ok using a hoya filter on the same location, so maybe my cheap filter don't work well at night time
 
A recent thread on this topic is never far away ;) http://www.talkphotography.co.uk/forums/showthread.php?t=342833

Sooner or later you will get problems with that lens, because the focal length makes it more prone to on-axis issues. Most likely outline flare and ghosting, and strange background patterns in back-lit situations, possibly some loss of sharpness.

Though why you should ever need a filter under that enormous lens hood, except in extremis, is kind of hard to imagine. Basically, don't.
 
I don't use protection filters unless I'm shooting in risky conditions (spume, blowing sand/grit etc) and I'm not convinced that a filter is really going to protect the front element against a flying stone, or anything like that, either. A lens hood has worked for me for a long time, but it's a personal choice.

Why don't you experiment with your own gear under different conditions? Nothing like satisfying yourself, before you make a decision.
 
Take that rubbish off the end if your lens and just use the hood!

UV filters serve no purpose on digital.

(yes, it's been said before!)
