Sensor resolution V focal length..........
I'm in need of some longer glass, longer than 300mm. It occured to me the other day that the crop of a given area of a frame would be consirerably bigger the more resolution you have from the sensor of the camera viewed at 100%. So I'm thinking 400mm on the K10D would be approximately 33% bigger at the same crop as it would be from 300mm viewed at 100% right? So if I'm using a K20D how much bigger would a crop of the same subject shot with the K10D be viewed at 100%, could I substitute pixels for focal length providing the lens resolution is up to the job? Are there any downsides other than the obvious differences when using a shorter focal length such as DoF?

RE: Sensor resolution V focal length..........
Thanks Paul, so in theory at least I could substitute pixels for the focal length I need to achieve the desired result.

RE: Sensor resolution V focal length..........
Thanks Anthony, I'd love a 400mm lens and a K20D. The trouble is I've been looking for a Sigma 400 f/5.6 APO tele macro to compliment the 300 f/4 APO I have but can't find one. I've been down the teleconverter route but now I'm thinking more pixels to achieve a greater print size hence the K20D is the logical choice, at least the K20D is still in production unlike the Sigma 400. Toine's shots were very good and I enjoyed seeing them epecially when I knew the lens used.

John, Put the 400mm on the K20d and solve all your problems at once ;-) But seriously, no one can tell you what will be acceptable to you. You'll have to set your own standards based on your own experience. Just look at Toine's shots with his new to him 38 year old T-Novoflexar 400/5.6. They're cracking good and couldn't have been better even if he had a brand new lens worth 10 or 20 times more. If you crop your shots, don't sweat it and don't tell us that you cropped. If they're good we'll tell you as much.

Hi Godfrey Yes I thought as much myself, it was early morning (7am) here in the UK, it's been raining the past couple of days and overcast so the light was not good. Exposure time was down to 1/200 sec @ f5.6 ISO400, I didn't want to increase ISO with the K10D, I prefer to keep below 400. I quite often stop at this place on my way to work, gather my thought for 15 minutes, sometimes taking a few shots. There's a boat house (now a cafe) in an area that gives any ultrawide lens a thorough test, it's the first thing I shoot with wide lenses. I'll post a PESO some day and all will become obvious.

There's a little bit of purple fringing at the edge of the frame in high contrast situations, you have to look for it, but it is there. The Sigma 300 f/4 APO that I've had for years is free of any such problems. I think I need to use the DA more before I can come to any real conclusions about image quality but it is sharp.

RE: PESO: Coots (Pentax DA* 300mm f/4)
Thanks Jack, much appreciated. Best regards, John From: [EMAIL PROTECTED] [EMAIL PROTECTED] On Behalf Of Jack Davis [EMAIL PROTECTED] Sent: 27 June 2008 22:00 To: Pentax-Discuss Mail List Subject: RE: PESO: Coots (Pentax DA* 300mm f/4) John, when I first looked at this shot I felt the image showed a bit of movement blur, but considering the unique and image drastic crop, felt it was certainly well worth posting. I have absolutely no doubt that the lens is capable of producing stunningly sharp, contrasty images and simply took this particular shot for what it gave, allowing that you were aware of its minor technical shortcomings.

Just took delivery of a DA* 300 f/4 SDM, first impressions quite positive. In comparison to my Sigma 300mm f/4 APO it'a a little lighter and less cumbersome but does not have the quick detachable tripod collar of the Sigma or the focus limiter, of course it is SDM and sealed. More comment and perhaps a PESO or two when I get chance to use it, maybe this weekend. Planning on a test against my Sigma 300 f/4 with and without TC's fitted.

RE: Enablement
Hi Jostein I cam barely control myself, I just want to get out there with some decent weather, but at the moment I'm in work and it's raining. The Tern shot looks very promising for things to come, really nice capture.

I wish Pentax would add a DA* 400/5.6 to the roadmap.
