Moving from Canon 35mm to Pentax 645Z

Pansottin · 12-27-2015, 07:13 PM

How big is a square file in centimeters/inches with 360ppi of resolution, from the Pentax 645z sensor?
Any link to a RAW Pentax 645Z file so I can make a test; please?
Thank you very much.

My Canon 100mm macro is the "L" version.

Yes, I've owned pretty much every canon lenses except the tilt shifts.

Thank you Gavin Cato (nice article about your quest for the Contax 645+Zeiss 80mm f/2 .-)

So in your opinion Pentax macro glass will make me forget my Canon macro glass (not the very special MP-E 65mm)?
You meant which lens; A or FA series)?

or
SMC Pentax-FA 645 120mm F4 Macro Reviews - 645 Telephoto Primes - Pentax Lens Reviews & Lens Database
Those are affordable lens. One manual and the other with auto focus like the Canon 100mm L.

Theres also this modern D-FA, with AF, modern coating and stabilization (like the Canon 100mm L) but the price is like a Zeiss Otus... .-(

If you want 1:1 you will need the 120. The 90 is only 1:2 macro I believe... The 120 is very sharp. I had the 100L with my 5DIII. In my view the 120 is every bit as sharp.

Thank you for your opinion. Yes I want at least one piece of glass that do 1:1.
The Canon 100mm L macro f/2.8 is my most versatile lens (macro, portrait, landscape, etc).
If I move to Pentax I need something like that. And a standard lens. I van happily work with just two lens for years; a macro and something between 35mm and 50mm (speaking of FF 35mm)-
The very special macro MP-E 65mm; I can use it with a Canon or Sony FF body (not a state of the art body but with a decent sensor, because its a manual only lens).

The 120 won't be too far off the 100mm FOV that you currently have. So the 1:1 position will be very similar to what you are currently used to.

I have the autofocus (FA) one. Others have the Manual focus (A). Apparently the optical formula is the same...

I don't do a lot of Macro. Most of what I shoot in wide angle landscape. Haven't used the lens for a while - will have a look though

I visited your Flickr (nice wide vistas) and you´re are using at least 3 cameras. Nikon (36mpx)FF, Sony (42mpx)FF and Pentax (51mpx)MF. Even with almost the same amount of megapixels today, do you feel that the MF results are better (all Sony sensors ,-)?
MF produces a "look"; an edge? Your opinion is important because you´re using both FF/MF.
I´m not considering the Canon 5DsR (50mpx) for my upgrade because the DR is known to be inferior.
