So, now my new HD DA70 has arrived, I'd like to fit a multi-coated UV filter / lens protector. I know many of you dislike the practice, but I'm in the habit of installing decent UV filters on my lenses to protect them, and to facilitate quick cleaning of the front element when I'm out and about.

With that said, does anyone know if using the original hood with a filter on the lens is likely to cause vignetting? I'm guessing the hood dimensions were worked out based on it being fitted directly to the lens. I know I can get rid of the vignetting in LR, but just wondered if anyone had real-world experience they could impart.

Thanks in advance

No, the hood doesn't vignette even with a normal-sized filter installed. Nevertheless, I would only use a filter in exceptionally dusty environments or when unable to clean for longer periods (e.g. wilderness hiking). Mind that the DA 70 comes with this beatiful hood and SP coating which really facilitates cleaning the front element a lot.

I do not use a UV filter but have installed clear filters on all my lenses, DA*16-50, DA18-135, DA35 f2.4, DA50 f1.8, DA40 Limited and DA70 Limited. Last sunday i went to the park and shot over 100 pictures with all my lenses and could not see any loss of image quality all were super sharp and no ghosting or flaring.

Apparently your DA* 16-50 is very different from mine: I do like its general rendering, but it flares like hell as soon as one ray of light approaches...

I just use all my lenses (including a DA 70) bare unless I want a polarizer or ND filter for the shot. I'm probably harder on my gear than a lot of people but have found the hood to be more than enough protection so far. Even when a tripod blows over in the wind.

I only use UV filter when the lens is exposed to water spray (usually at sea shores) or places where there would be sand. Dust is usually no problem, as a rocket blower would take care of it, but I'm wary of sand as it can easily scratch the coating or the glass. For everywhere else, a hood will be more than enough.

Thanks for the responses. As I said, I know people are polarised on the subject of using a protective filter... For me, I'll always use them wherever possible, though I try not to stack filters. It's good to hear others are using a filter and the hood on the DA70 successfully

I have the DA 17-70.
It has a very convenient built-in hood, I keep it always mounted, and, IMO, it is a very efficient protection: an UV or clear filter is useless and can only bring you flare, softness, and lower contrast, which would be a pity as this lens is the sharpest money can buy, with an outstanding transmission.

I've found these filters to have zero effect on IQ. Very high quality!

I take your point, but each of us has different priorities and will accept different risks. Me - I'll accept a small additional risk of aberrations from a *good* MC filter in return for being able to clean the front element easily whenever, wherever and however I want, without risking damage to the lens or coatings.

You know the pros and cons of using filters and have made an informed decision to use them. I find it curious that people can't just accept that.
