I doubt anyone could dispute any of the above Jack. Same logic process I went through when initially ordering the H4D/60 over 5 months ago ... however, there still is no Hassey 60 camera :wtf:My .02 on the crop factor, offered FWIW...
1) It is a double-edged sword. On the one hand, you have true "full frame" capture, which gives you the widest capture possible with any given lens. However, with the crop, you are using the sweetest spot of the lens, so have better corner-to-corner sharpness, and actually get a little longer net focal out of your lenses which can be as beneficial as getting wider...
1a) While we're discussing crop, IMO even a 30MP image is still a pretty great file to work with!
2) Speed. The new 40's are faster than the 39's, but the new 60's are about half-way between.
3) Not really relevant to the discussion, but: You can crop a 60 to the 40 and maintain all of the IQ and perspective advantages of the 40, while maintaining the size advantage to the 60. Also, you only give up a little speed to the 40, especially with Phase in the binned mode.
FWIW, #3 is one of the three main reasons why I chose the P65+...
In that 5 months business got worse not better ... so sinking 20K into the next step seemed a bit crazy (besides, I spent all my war chest funds on M stuff, speaking of crazy :ROTFL Now I can do the work I am getting paid for ... and wait to see what happens. What quality level the H4D/60 really is, and how it actually stacks up against the 50 Multishot, etc.
I've seen some ISO 1600 stuff from the H4D/40 and it's a leap forward from the H3D-II/31 which wasn't bad itself. For my type of shooting that will help ... and it's still 40 meg
The other thought I had was to take some of the proceeds from the H3D-II/39 sale and get a cheap H3D/39 ... which has the same trade value toward a 60 as my pristine H3D-II/39 with only 3000 shots on it! I'd be ahead by about $6K doing it that way.
