Focus Issues with 55-300mm and Circular Polariser
Hi to Chris & Tim - of course I would be very happy to let you know how the Hoya goes on. I've done a bit of research since posting the thread and it seems that problems with Circular Polarisers and long zooms are not uncommon. I also tried the filter on my son's Sigma 70-300mm DG APO and suffered...

Focus Issues with 55-300mm and Circular Polariser
Hi, I have just got the same problem with my L 55-300mm. I have purchased 55-300mm lens together with my camera and basic 18-55mm lens. It was working fine with UV filter before. However after my last visit in London I have found that my lens is not focusing as sharp as it was before with or with...

Focus Issues with 55-300mm and Circular Polariser
Just to clarify, I don't have any problems with my DA L 55-300mm lens. It only has issues when used with a circular polarising filter, not on its own or with a UV filter. It sounds as though your lens has developed a fault and you should get it checked under warranty if you can. As far as lens re...

Focus Issues with 55-300mm and Circular Polariser
Hi all I'm sure others have experienced the issues I am having at present. I often use polarisers, but have only recently bought a 58mm for my DA L 55-300mm. I have found it useless as the lens focus is so soft with the filter fitted that the pictures are not worth keeping. This worsens the lo...

Focus Issues with 55-300mm and Circular Polariser
Bit of a digression, I know, but following this thread did make me think. I have an old Hanimex 500mm mirror lens (original T-mount in Pentax-K) that has never seemed to be quite sharp. It came with a Hoya 72mm 1B filter, which has never been removed. This thread does suggest that I should try th...

The 82mm diam. filter on the Tamron 500mm was part of the design and actually improved it's sharpness :wink: http://forum.fourthirdsphoto.com/showthread.php?t=18954 It's just a myth that filters reduce sharpness. Some filters actually improve it particularly at the edge of the frame :shock:

The 82mm diam. filter on the Tamron 500mm was part of the design and actually improved it's sharpness :wink: Mebbe so, but I don't have a Tamron. And, some mirror lenses (including at least one Tamron, I think) had a rear filter system that was part of the optical design, and had to be used. It...

Lenstip also have quite a good test of UV filters. Surprisingly the Hoya HMC UV-0 came out best The shot of the balcony does look better with the filter than without. It's not clear if it's a crop or not. They do mention on one of the reviews that apart from where they have noticed proble...

Funnily enough I also have the Hoya HMC UV filter though it is the UV(C) version rather than the UV(0).

Funnily enough I also have the Hoya HMC UV filter though it is the UV(C) version rather than the UV(0). Bad marketing on Hoya's part, theres also a UV(N) :shock: :shock: Nobody has a clue what they mean? ..... possibly Normal and Compact. UV(0) is the original Kodak Wratten ID for a UV filter, ju...

Those of you using long lenses with a CPL, can you tell me what it is you are photographing and why the filter would enhance the image?

Those of you using long lenses with a CPL, can you tell me what it is you are photographing and why the filter would enhance the image? Sorry for the delayed reaction. Didn't see this post when you originally wrote it. Firstly I like to shoot parts of the city (Edinburgh) with a long lens. Rather...

Seems that this issue is not common, but is also not unique to Pentax lenses. For example http://askville.amazon.com/SimilarQuestions.do?req=Nikon-D80-70-300mm-zoom-lens-circular-polarizing-filter-images-blurry-VR-shake. http://photography-on-the.net/forum/showthread.php?t=103008 Several ...

You can always add a little blue to taste with either the WB tool or filter.

Snowy scenes also reflect a lot of UV light, especially in high mountain areas. Our eyes aren't too sensitive to UV light, but the sensor on your camera is, and that increases the blue hue you get on your pictures. Using a strong UV filter while taking the pictures will help in keeping the snow wh...

The lens coating and the coating on the filter in front of the sensor blocks the high-end of the UV at least, that's the part a normal UV filter also blocks. Seems to me a bit pointless to do that 3 times. What might help is a Haze filter, that one also cuts out the lower ends of the UV light.

Take my word. When you're high up, you definitely get a blue haze in the pictures that will go away with a strong UV filter. I believe you but strong UV filters are called Haze filters, they are even specially made for what you describe. That bluish cast for example is called haze. :wink:

K20D fuzzy image problem.
The sensor is held in a particular position by the magnets whether SR is on or off. If something is stopping it being in that position then the SR will keep trying to move it to that position. That's the noise. I had this with a camera where initially it worked but then the frame that holds the ...
