filter thread?
Size, simplicity and compatibility. First two aren't the problem it's the last one that's the deal breaker. Just look at the way most lens hoods are attached, the functional bit is just as high as the filter thread inside, it's only slightly thicker though but I'm happy to trade in 2mm to make it...

Too bad it didn't catch on John. :( Strange actually... In the time when B&W film was popular (sixties?) some people surely would have thought that a thread takes quite a lot of time and fiddling around when switching colour filters, or white balance filters for colour film.

Well Hoya has Pentax and have Tokina as a good friend. B+W is part of Schneider and they also have Pentacon/Practica. As you know Samsung lenses are sold under the Schneider name so they at least have some connections with each other. They could make an adapter for their lenses so that you can ...

Have a look at a Rolleu filter Stefan and see forsty how small it is and then how highly engineered the bayonet is. Not just a simple turn and click like modern ones, but high grade steel and ball bearings and springs.... To make something like in in say 67mm fit would result in a lens hood costi...

Does the Pentax 67 not have bayonet filters?

I had a quick look when you mention it John, didn't saw that it was so complex :? A simple turn and click like a hood looks like it should be enough. At least I never had a problem that a hood become loose or anything like that and a hood is heavier than a filter. Just dreaming here though. :)

Does the Pentax 67 not have bayonet filters? I believe so, but I've never examined them closely. They are horribly expensive!

Does the Pentax 67 not have bayonet filters? Looks like thread to me but I can be wrong.

As someone who's owned a few Rolleis I have to say their bayonet filters (both the TLR and system camera varieties) are a joy to use - massively over-engineered (like everything Rollei used to make) but deeply satisfying. The down side is that they cost an arm and a leg and they don't do anything a ...

Tamron 10-24 opinions
I did a couple of landscapes yesterday... this is with the 0.9ND and the 10-24. Unsharpened, just exposure / curve / WB 'corrected'. That's a very nice shot, but there seems to be some severe vignetting in the extreme corners: I assume this is caused by the filter holder rather than the lens itself?...

Tamron 10-24 opinions
at least on the top corners, it's because I was shooting directly into the sun and it's a strong ND. Bret The most noticeable is actually the bottom-right corner, and it's fairly rounded which is what made me think it was the edge of the filter holder rather than the effect of the filter itself.

Ebay`s ok by me
Blimey, just received a Sigma 24-70mm F3.5-5.6 Aspherical AF which I won on Ebay for £15 + £3 p/p - boxed with a Hoya filter and indistinguishable from new. Says on the box and in the `structions that it is for PA-Z ( Z series ) and Z70 or otherwise only usable in manual mode not autofocus ???...

Sigma 17-35mm f/2.8-4 EX DG
Hi all just been offered the 17-35mm I fancy it but thought I might do some homework anyone here have one of these or know if it is likely to be worth the £130 being asked ?this included a 77mm Hoya filter and hood plus carryng bag.It is in really nice condition not used much at all Thanks in ant...

Sigma 17-35mm f/2.8-4 EX DG
I'm guessing this lens was intended for a full frame camera? If you're going to use it on a Pentax dSLR I'm not sure if £130 is worth it. You should be able to pick up a Tamron 17-50 for around £200 used, and to me the constant f2.8 and extra length would be well worth the extra £70. 77mm is a h...

UV Filter fogging the element
So it's pretty hot today with a bunch of humidity in the air. I just put a UV filter on a lens and the UV filter/front of the lens started to get fog on it. Is this normal? If I leave the filter on long enough will the fogging go away?

UV Filter fogging the element
Take it off! You are unlikely to need it - contemporary digital sensors have little if any sensitivity to UV when compared to the film emulsions of 35 film SLRs. If you have a front lens element that needs special protection (not sure why!), then perhaps you might consider a UV filter -otherwise, ...

UV Filter fogging the element
front lens element needing protection - its cheaper to replace a UV/skylight/whatever filter when you drop a lens/camera, than it is to replace an entire lens surely?

UV Filter fogging the element
front lens element needing protection - its cheaper to replace a UV/skylight/whatever filter when you drop a lens/camera, than it is to replace an entire lens surely? The front element is very hard and suprisingly resistant, filters generally aren't. I picked up a M35-70 (I think :? ) as part of ...
