Re: Fun with MF images - Part 3
Guy: If I can recall well, you sold your P25+ for a P30+. What is your experience doing this change? Weren't you bothered by the smaller groundglass image? Or by the bigger lens image cutoff? What do you find better in the P30? Is really better image quality to have a smaller sensor with more pixels than having a bigger sensor with less pixles?
Well, sorry for so many questions

Great question the big difference between the P25 and P30 was the extra gain in ISO. The crop factor and going to a smaller 6.8 from the 9 micron sensors I gained a lot in the way of moire or should I say the lack of it more. Now what I noticed on the 6 micron P40 it is even less than the 6.8 as well with regard to Moire. Seems the smaller micron backs handle moire better. Now going to a smaller sensor with more pixels I have not found that to be any issues on the quality front and if anything it has improved since we are going up in total MPX so less enlarging of the image as well.
So making these 22, 31 and 40 MPX jumps has helped overall on the detail front as well. The P40+ has more overall detail than the P30+ but again these MPX jumps you have to be careful they are their for sure in the details but not earth shattering either until you get really big and I mean big. I think you will see this in prints on the larger sized like 30x40 going up maybe even starting bigger. This is something I have not tested but feel very confident they can handle it with no issues.
Now each back comes newer tech with it and the P40+ with sensor + adds some nice features and I really like this back and for the overall money new out the door of it 19k is not bad at all. It's only real limit is a 1 minute time exposure compared to like the P45 at 1 hour. I would like the P40+myself I feel it is better than my P30+ back but at the same time looking what I just shot I am really lacking nothing per say. If you look at Charlie's P20 shots with his Alpa the detail is just gorgeous and that is 18 mpx. Go figure.
I think it is safe to say as we go up in size we can get bigger detailed prints as we do that but at the same time some of it gets wasted on use. That's okay though I would rather have the strong file when the need comes up you are not painted in a corner. I have been burned by clients on this making things bigger than anyone ever thought they would do at the time of shooting.
