Welcome back. I remember seeing you mention your site on here before. You provide a very useful service and it greatly helps to keep Pentax alive.

That's quite good, but I was thinking about 60fps rather than 24fps. No more decisive moment more like decisive hour
The Pentax K-5 already stores video (Motion JPEG) as single jpg frames (actually half + half) I used to dump them a thousand at a time to ramdisk and pick out what I wanted. I used Asfbin to do it.

Very Nice Stan ...... but I still think you would have been better buying a 'Charles Atlas Bodybuilding Course' I paid for one back in the 70's, but the ba$tard never sent me my muscles

It's a lot better with the Pentax 24-90mm. Unusable on a K-5, but nice on the K-1.Good to hear of your good experience. I want to suggest that the focusing noise was due to an SDM lens being used. It's just as loud as ever with screwdrive lenses

Older lenses used to be better stopped down at least two stops. Nowdays they can be designed to give excellent results wide open. The Pentax DA* 300mm f/4 doesn't get any sharper stopping down except when the 1.4x TC is added in which case one stop down is better. The 70-200mm f/2.8 is very sharp wide open and I would expect it to be better than an f/4 lens. An f/4 version could be made to be sharp at f/4, but to save on costs it might not be.But f4 v f2.8 raises a technical question that I don't quite understand.

I can't use either the K-5 or K-1 without the Pentax O-ME53 Viewfinder Magnifying Eyecup. I hate the smaller view without it. I wonder if mirrorless would be the same?
Can a magnifier be used with mirrorless. Is the view small without?

The vignette on No: 20 works well because it makes it look like an old faded colour print from the same era as the truck.
The edge fading on such old prints as often caused by not only the lens, but also light leaks into the camera or just light getting to the edge of the photo if it was stored/stacked poorly.
