apart from giving protection to the lens,what effects does UV filter have ,will it make the photo less sharp,if there is little sun is it best to take it off whilst shooting.
thankyou

I have a Hoya Digital filter for my Fuji and the IQ gets a lot worse, when I have it attached.
Strong flare and less sharpness are the major reasons, I don't use it anymore, so I would be happy if someone knows of one that works well.

I have a multicoated Hoya protector filter on my X and can't see any loss of IQ. Even there is any, I like the peace of mind and it makes the shutter even more silent.
I'm on my 2nd filter now because although I really take care, the first one somehow got an ugly scratch after a few weeks. Better the filter than the lens.
I was shooting waterfalls in light rain last week and got some drops on my filter. In the filter, it's easier to remove the filter than to start cleaning your lens.
Remember that you need to use the Fuji adapter or a spacer ring to mount a filter, otherwise the lens will hit the filter in macro mode, resulting in the camera to turn itself off.

Ive attached a hoya uv filter but didnt put a spacer ring or adaptor just screewed the filter on, so are you saying thats incorrect?
Thanks

Yes - if you try to focus on near objects (i.e. at macro distance) the lens moves forward to project out of the barrel, by a few millimetres. If it touches the filter, the camera will display the message as described in flood's post above. Inserting the spacer ring solves the problem.

I use a UV filter occasionally, but always with a lens hood to inhibit flare.
Even with that I once got a strange effect from a window - appeared to be light reflecting back and forth from the lens back to the filter back to the lense. It was peculiar. But I always use a filter in windy outdoor places (with a hood, as I said).

It sounds, from your description, very similar to the effect that I encountered when using a filter on the x100 - while photographing an indoor scene... included in which was a window.
daveleo
what?
Yes, that was exactly my situation as well.
I say it was reflection back and forth betwen filter and the lens because the patch of "flare" had the exact same shape as the window in the picture. And it went away when I removed the filter.
Wish I had kept that image !

I've noticed a bit of glow/flare when using a UV filter on my X100 (B+W XS-Pro Digital with MRC Nano coatings). So I only put on the filter when I'm taking the camera to the beach or someplace where the need for protection warrants the IQ degradation.

I have never noticed this unless I am shooting toward the sun. I guess I will pay more attention..
I always use a multi coated uv filter plus a lens hood.

the front lens of the X100 and X100s looks very fragile and since I don't like using hoods, I decided to use a UV filter on it.
cant remember the brand right now but i didn't really notice any IQ degradation to take it off.

I keep a filter and adapter ring, with the filter capped, in my bag. I only use it in rain or spray. Nearly all the time I keep the camera as it came, carrying the hood in my little bag too in case I think I'll need it. You might see the deficiency of this as having to unscrew the thread covering ring each time I want the hood. I could leave it off permanently, but mad though it seems, this is what I do.

Curiosity got the best of me. I went upstairs and duplicated the effect again. These don't look exactly as I remembered but you can see the reflection, just to the right of the window in the first photo. Looking in the EVF, it is VERY much more obvious that in the pictures. The "reflection" seen in the EFV is a very clear image of what if outside the window !!
The second photo has no filter.
This was a Tiffen UV filter, don't know if it is coated ??
I cannot see this "ghost" using the OVF .

UV filters provide no real advantage to a digital sensor. Protection is a different story.

Looks like internal reflection between the filter and the lens to me. Will give it a test next chance I get. All my filters are multi coated except for some early Nikon ones I have from ais days. I will dig around and c if I can find a none multi coated to c if I can recreate the problem.
But it looks like direct sun light window situation about 30 to 45 degrees off center maybe about 7-10 feet from the window, correct?

No . . . I cropped the image (a lot) for posting the area I wanted to show.
I am about 12-14 feet from the window.
That is not direct sunlight, it looks out to the Northeast corner in the afternoon, so it's 180 away from direct sun. HOWEVER . . the room is dim and outdoors is very bright today, so there must by 4-6 f-stops difference (offhand guess) in the light.
I am 90% sure this is an uncoated filter as it is not marked "multi-coated". I'm too lazy to gostairs and dig out a coated filter and retest

i just realised with the hood attached there is a clearance already if i wanted to attach the filter.correct?
thanks

The hood is attached to the adapter ring, so you already have that. So as long as your installation order is lens->adapter ring->filter, you're good to go.

For the record, I cannot duplicate this effect using my D5100, a 20mm lens and the exact filter that I used above. I can get this setup to flare looking into the sun, but cannot get that "ghost" image of the window.
My current thinking is that this effect happens due to the uncoated filter and the radiius of curvature of the front element of the X100 lens. The size of the ghost depends on how far the filter glass is from the lens glass.
I think.
My take-away: keep your eyes open when you shoot into bright patches and use uncoated filters on the X100.
I've decided to go back to the pentax dome hood ( for best glass protection ) and use no filter and stop worrying about this.
