Re: Re: Geso: photos taken with Pentax mount glass on full frame, camera
Thanks for the look & comments, Alan. These were very informal tests. Many variables go into sharpness. None of these was shot on a tripod for example. Glad you saw some familiar plants; I just love greenery. Yeah it's the math of APSC. that gets to me sometimes.

Re:Re: Geso: photos taken with Pentax mount glass on full frame, camera
Bob, Thanks for taking time to look at the photos & thanks for your generous remarks on my photography. Oh I did shoot film, slides mostly and developed and printed my own. I was shooting a Ricoh with pentax mount lenses because I could not afford the real thing. 90% with that Sears branded 50mm and & 10% with cheap telephoto. No wide angle. My 1st real digital was Pentax 200D. This little experiment was to see which lenses would carry over to Pentax FF and if not, it does not bode well for the success of Pentax FF. If as you say (I I do not dispute) the buyer needs to buy new higher quality and higher priced glass the why go Pentax? Just go Canikon! Unless the Pentax is so inexpensive it lessens the blow of new lenses. Sony has the merit of smaller sized cameras for FF. But it turns out that fast FF lenses are rather large. The A7 & a 35mm lens weighs 3 lbs and ain't pocketable. Advantage Olympus for size & weight. back to Canikon for lens selection. If I were to go Sony their 35mm ($1500) and 50mm ($1000) are among the sharpest lenses ever tested. Money no object it is still a big commitment. Many people on the web are raving about using Leica glass on the A7 but we all know those are pricy too. And all adapted lenses are manual exposure & focus. Except for Canon lenses which work as native on Sony with a $3000 dollar adapter. I would keep Pentax cameras & some lenses for sports, birds, if nothing else for the reach of the teles. & my K01 with a pancake or even the 18-135 is a fun kit for the casual walkabout. Thanks again for giving me all this food for thought.

When I moved from film to digital I had a very high quality Contax / Zeiss film kit. Using the lenses with an adapter on Olympus 4/3rds gear I noticed very significant purple fringing with some of the lenses, which meant they were effectively useless for digital, so I sold all the Contax / Zeiss stuff. So the first thing I looked for on your shots was purple fringing because I think (could be wrong) that it results from the different alignment of pixels and film wrt the light path, and subsequent interference between pixels. I didn't notice any in the shots of yours that I looked at. What I did notice is that at full magnification your shots are softer than the quality of your photography deserves. You don't say specifically which models of lenses you use, but I suspect the softness is in the glass, not including the fullness of the frame. You should try and get hold of two or three equivalent focal length Sony lenses and shoot comparisons with your lenses under controlled conditions, as best you can. Your pictures deserve better lenses. Go for quality rather than quantity.
