Focus Issues with 55-300mm and Circular Polariser
I use a circular polarizer with my DA 55-300 with no problems. Images are perfectly sharp. The one I use is a Marumi DHG Circular P.L.D. The 72mm version was highly rated in testing by and I've found the results to be good.

Focus Issues with 55-300mm and Circular Polariser
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...

Focus Issues with 55-300mm and Circular Polariser
Funnily enough I also have the Hoya HMC UV filter though it is the UV(C) version rather than the UV(0).

Focus Issues with 55-300mm and Circular Polariser
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...

Focus Issues with 55-300mm and Circular Polariser
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?

Focus Issues with 55-300mm and Circular Polariser
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...

Focus Issues with 55-300mm and Circular Polariser
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 ...

Settings/PP for shooting in snow
I'm also not very technical either. In most situations i shoot in manual, press the green button to take a metering, take one photo and look at the histogram and adjust and take a photo again. Once the exposure is like i want it i leave it like that for as long as i can, it might mean that the sha...

K20D fuzzy image problem.
I fear I know the answer to this one. :( I am in Romania for work. The other day I went to take a picture of a large Roman tower and the images were very very fuzzy despite bright light etc. Back at base I decided to test the camera further and so I set it up on a tripod and used the 2 second...

Does your old manual lens crash your DSLR when it gets dark?
Ok I am not being stupid and using a manual only lens in auto mode or anything like that. I have a K5 and bought a good quality SMC-M Asahi 50mm 1.7 for the princely sum of €24. This lens has no A mode. I do put it in M mode (and manual focus mode of course) and permit use of the aperture ring...

Does your old manual lens crash your DSLR when it gets dark?
Have you turned on catch in focus,this won`t allow you to take shot if green hex is not showing. Have you tried setting camera to manual on focus mode lever,on the front of the camera. I have used K35 f2 in very dark light,overcast at about 10 O`clock at night, I would set shutter speed to 30 ...

Pentax-F AF adapter 1.7x
If on the outside they may be the result of an attempt to clean the glass, and might come off if you use acetone or a proprietary lens cleaner. G That could be a possible explanation. I will buy some lens cleaner on Monday. Owch that is a good price ... still not sure I would be happy though. ...

Pentax-F AF adapter 1.7x
Change of heart? Not really Mike, Got mine for a good price, and 3 months later sold it at a good profit, however; TBH I think this is an over rated lens. ( quick duck under table to avoid the sure to follow abuse.) The idea that it makes a MF lens into an AF is only correct if you have alr...

Pentax-F AF adapter 1.7x
Given that you see the "stains" only after breathing on the adapter, it seems to me that simply some moisture makes it inside the adapter. If that's the case then a) you shouldn't be able to wipe away the "stains" and b) they should disappear after a short while on their own. Provided that it is...

K20D sensor problem
I've produced an action that gets rid of the blob and the line, at least with the line vertical on the right like your example. Just puzzling out how to save the action so you can try it. Still large: One way to do this would be to always rotate the image to the same orientation, run the act...

Lack of battery grip
Can anyone explain to me why there's not a grip available for the Kx ,i used to own the K100D a couple of yrs back which i used with a battery grip It also used 4 AA batteries . Reason i'm going on about it is that i have rather large hands and on more than one occasion i've nearly dropped the Kx.

Getting a lens fixed.
Hello I have recently been travelling for 5 weeks and after all the back packing the only casualty is regrettably my 28-80mm standard lens, which i use a lot with all my Pentax SLR's. It's so loose it can hardly focus. My question is, how do i go about getting this fixed? Do i just hope to g...

How to clean faulty shutter wheel
If it's under warranty then send it back (which camera?) If not then personally I would send it in for paid repair, I certainly wouldn't be spraying anything into the command dial. Another Pentax problem that seems to be getting more and more common. :roll:

How to clean faulty shutter wheel
Thanks, but this is definiately not a "user" problem. It jumps up and down at will when turned (sometimes going up when should be going down), skipping speeds sometimes, then back to normal, then 1/2 stop, or whatever.
