H3D -22 - 31 -39 Differences?

[pflower]

There are some very attractive secondhand deals at present on all of these - the differences in prices not being that dramatic. I have looked at an H3d-22 which I liked a lot but can anyone give me an opinion/run down/comparison on the 31 and 39 backs.

I do mostly landscape/urban, some portrait and some macro work. I have never printed above A2 size but might one day consider it - but most of my stuff now is A3+ (and am going through a phase for A4 which may pass).

What are the advantages/disadvantages of each of these backs against each other. Presumably there is something other than merely increasing the number of pixels.

Thanks for any suggestions

I suggest you check some of the older threads here.

Whe using the search option look for posts from Marc Williams.
I am sure he explained in detail what the differences are.

I have been through them all. The most important difference, other than the sensor size which is obvious, is noise. The H3DII uses a heat sink that reduces noise better than the fan operated earlier version.

You may not see the difference. I did. For large prints, it is there, but various sw can remove much of it.
