Help me with a weird problem
Hi all. I am going to describe to you a weird problem that I encountered today and wonder if you can give me an explanation. It goes like this: I have a Pentax A* 300mm which I was messing about with today. I decided to see what sort of results I'll get with a CPL filter, so I stick one on. Suddenl...

Help me with a weird problem
A picture would speak a thousand words here, I feel! I haven't noticed any problems with using a LPL on AF lenses btw - but I admit I have not checked whether there's a problem with critical focus at large apertures etc. The only thing I can think is that the reduction in light means you need ...

Probably the 2 stops or so lost through the filter causing camera shake. Even the 2nd shot should be sharper it's a top lens. Edit: Just noticed they are both 1/60th and the iSO was changed. You need at least 1/300th with a 300mm lens? It still looks like camera shake.

Come on guys give me some credit. I have been taking photographs for long enough to know when there is camera shake. The picture you see is exactly what I saw in the viewfinder. When I started the thread I hadn't evrn taken a photo - I had been talking about what I saw in the viewfinder. Cheers ...

... When I first looked in the viewfinder I thought I had changed the diopter by accident. I think that testdasi is right based on the above. I stick with my previous comment re low quality filter. What brand is yours?

I suppose the problem is the Filter. For some reason the AF on the camera gets in conflict with the circular lines of the POLA. The solutions are two: 1) Test the lens with a linear Pola. 2) Lock the focus with AF-Lock button and then insert the POLA. If it is still blurry the best use you can d...

As has been said many times, this is the filter. It is faulty and should be binned or returned.

Wide Angle - Prime v Zoom
Why not Sigma 8-16? If using filter is a critical requirement then the Sigma 10-20 is another good choice. by , on Flickr by , on Flickr by , on Flickr

should i sell my 31mm?
hi all, of all the lenses i should want to sell, it's arguably my finest one: my 31/1.8. the reason? i've settled on a 49mm filter set (goes with the da limiteds and the 135/3.5). i've also settled on small lenses. i still own my 35/2.8, which is a bit smaller (materially so, since i do kee...

should i sell my 31mm?
If it helps, i used to use that 31 with a stepdown ring to 49mm and used my 49mm polarizer on it (like you all my other lenses used 49mm filters at the time). Since the 31mm was built as a full frame lens, stepping down to 49mm resulted in no vignetting. I recently acquired a K-135 f/2.5 which i...

You said it, it's your finest lens. Contemplating giving it up because you prefer a 49mm filter thread is a bit like trading an Aston Martin for a Nissan Qashqai because it's got more cup holders, IMO. ;)

Macro Lens Image Sharpness
Macro images generally need lots of light so that you can use faster shutter speeds to 'stop' motion, and/or smaller apertures for larger depth of field. For static subjects like flowers, additional lighting is not always necessary. For bugs, you'll quite often need extra light from a flash and s...

Lens Advice, please?
I have no idea why people think a macro would be a good lense to take to Mongolia. We are talking wide wide open spaces on the plains, lakes, rivers, people for sure, horse-riders, congested chaotic cities / towns and possibly temples. If it were me I'd be taking a Sigma 10-20 (or similar Pentax ...
