I doubt that you will achieve the necessary quality when using heritage lenses with adaptor rings. It would be quite possible to increase the size of an image file from a camera such as a Canon 5D III, which is 22 mpx by applying interpolation in editing software, or even better, from a Nikon 800D which is 36 mpx, but the image quality of the original file would have to be really excellent to begin with. That equates to just over 58 mpx (million pixels). If, for example, you were to print your 30"X40" prints at a resolution of 220 ppi you would require a file size of 6600 X 8800 pixels. Very large prints may be printed at a lower resolution, depending on the viewing distance.
Holly, standard practice is to print at a resolution of 300 dpi (dots per inch) but for purposes of this discussion you may read that as ppi (pixels per inch). I want to have the shots printed to at least 30x40".what pixel size would accommodate this? I have Zeiss C/Y and Bronica ETRs glass and cannot afford much, what older EOS model could you recommend that would accommodate both-with adapters of course. Hello, I have read through this and the "old glass" forum here is my question: The two boards that probably have the largest knowledge bases about putting old lenses on new digital cameras would be mflenses and the Fred Miranda alt. If you desperately need to use lenses that aren't marked as usable on that database, then consider a crop-body or 1Ds/1DX instead, or do some more intensive research on the specific lens/body combo you want, as that database is old. There's a database on C/Y mirror clearance on the 5D at. This is typically a problem with wider lenses. Some folks report that they have no issues (no idea if it's AE vs. Usable, if I keep the focus range within mirror clearance, though. My Distagon 28/2.8 (AE version) is problematic on my 5DMkII, as the mirror hits the back of the lens when it's focused to infinity. longer ones, there's the issue of mirror clearance if you go with a 5D/6D. But I've used cheap rings and done pretty well.ĥDMkII + C/Y CZ Planar 100/2, with chipped adapter ring off eBay (seller: big_is). Generally, the more you pay, the better the tolerance. The things to look for in adapter rings are the tolerance and whether or not you're able to focus to infinity, at infinity, or past infinity. If you want rock-solid adapting for heavy lenses, the Leitax kits are probably the best-no play at all when you screw to the lens mount vs. A 6D or 5DMkIII would be the current models to look at, but a 5DMkII or 5D ("classic") might fit the budget better.
I've used C/Y Zeiss on crop and on full-frame, and it just feels better (and you actually go wide) on full-frame. No idea on megapixel count, but I'd say go for a full-frame Canon if the budget allows, and your lenses will clear the mirror, simply so that your lenses will behave more closely to what you expect.
