Sigma 10-20
Time for a brick wall and a tripod I think :D For me that always seems like a good test as you have a flat surface with lots of texture if you get the right light and you really ought be able to get a good focus too. Boring but helpful and the tripod will eliminate any camera shake which again...

Make sure the lens is set to the A position, that lets the camera and lens 'talk' to each other. As for focusing, the viewfinder shows a red square in the centre when in focus(ish) and a green hexagon on the display at the bottom of the view finder when in focus. You could set catch in focus i...

Hello welcome! Well they do have a focusing screen but not like the split screen you're refering too I believe. You can replace your screen with such a split screen, makes them but there are also other cheaper solutions. This is how the viewfinder looks like off the K20D Normally you don'...

That is a good price. Also see http://www.srsmicrosystems.co.uk/1623/Pentax-K200D-Digital-SLR-Camera-with-Pentax-18-55mm-Mk2---55-300mm-Lenses.html - Freepost if you mention you're a Pentax User Forum contributor. Also consider the K10D for a better viewfinder and an extra control dial.

There seems to be some confusion over the red suares in the viewfinder. They do not show when the image is in focus, but rather where the point is that the camera is focusing on. The green hexagon is the in-focus confirmation light and can be accompanied by a bleep if that is switched on. Of c...

deciding on long lenses - bigma / 300mm prime
Hi Am wondering if anyone could offer some advice on long-lenses for wildlife photography. Have looked through forums on long lenses, but can't really find the comparisons I was looking for (but sorry if I'm repeating questions already asked). I already have a Sigma 170-500mm lens on a k10d, but...

SDM does work with the Tamron MC4 1.4X though. I went for an older Pentax F* 300mm f4.5 which works nicely with the Tamron 1.4 Teleconverter. It also works well with the SIgma 2X DG EX Teleconverter I bought for my Sigma lens (although in manual focus only).

If you used them on your Super-A then they'll work just fine on your K200D. Zoom technology has come a long way over the years so don't expect the Sigmas or the Vivitar to be any better than the current kit lenses (and manual focus of course), however, the Pentax A50/1.7 should prove to be a very...

hardgravity is right. ricoh "P" lenses and Third party lenes r-p/k or pk-a/r or similar should not be used on Pentax Auto Focus. The aperture contact required for Ricoh bodies lines up with the focus drive of the pentax body and lockes then together
