Title: Test run of Rollei lenses, wide open, on 80MP sensor
Post by: Graham Mitchell on July 22, 2011, 06:21:25 pm: Those who think these old lenses aren't up to standard for 80MP digital sensors might be in for a surprise.

Here's a quick run through of my lenses (except the 150mm which is in storage), all shot wide open in my kitchen.

I might not have nailed absolutely perfect focus (it's 2am here!) so please bear that in mind. And also bear in mind that these are shot wide open, where resolving power of the lens is at its lowest.

Would love to try some of the latest generation AFD lenses on this camera!

But still not blurred, so go on with your tests ....

Graham,

Jerry

Yes, nice equipment and very capable lenses. (what I liked in the kitchen is the no-smoking sign just above the cooker)
Graham, are those the lenses you are using regularly in your works?

Jerry, beautifull sense of composition and beauty in your approach. Really liked your work.

Yes, almost all my work has been shot with them.

Post by: Graham Mitchell on July 22, 2011, 09:29:07 pm: I just tried processing a file in Leaf Capture. It actually seems more detailed than the Capture One images posted originally, so I have added the Leaf versions too.

Post by: jeanlucco on July 23, 2011, 02:50:55 am: Graham, well done! Being French I would recommend you to perform the same tests with a nice Chateau Margaux 61. I am quite sure that the sharpness will improve ;) anyway, no doubts that the "old" lenses are still on the top. AFI/Hy6 + Schneider + AFI ...II form a winner trio. IMHO the system is not dead as many people are mentioning. Take care. Jean-Luc

Post by: lowep on July 23, 2011, 04:43:08 am: Would it make any difference to the sharpness if the bottle was empty?

Post by: TH_Alpa on July 23, 2011, 05:18:41 am: Graham,

I noticed some colour balance changes in the images processed with LC, as well as a sharpening.
Did you change the white balance, respectively did you sharpen the images? The colour change is also noticeable in the dark contour lines.

Cheers
Thierry

Thierry, it's true there is a colour shift but I left the colour balance settings where they were as all I was interested in was the resolution test. Please ignore colour balance.

Post by: ced on July 23, 2011, 05:46:12 am: Hi G! Interesting!! What distance from back to bottle? Default sharp settings are okay for print but a tad too much(overcooked)for web display, I am sure you are aware but others may not be.

Post by: Graham Mitchell on July 27, 2011, 03:30:27 pm: Here's an amusing little real world example of the resolution of these lenses and back. I saw a fox from a distance a few days ago but had my 80mm lens on the camera and I knew the fox would be gone in a second, so I took the photo with the 80mm thinking I would see how it looked blown up later. I wasn't really prepared for how good it was :)

Post by: uaiomex on July 27, 2011, 07:12:13 pm: In this one she briefly shows with a Hasselblad. It seems to me that she may be testing MF under real circumstances to evaluate right to the core.

It's completely unimportant to me what she uses, but you're right.

Post by: lowep on July 28, 2011, 06:32:45 am: Very truly amazing fox: so does this mean it is no longer necessary to invest in or carry around a telephoto lenses, and also open up a new possibility to shoot objects at a distance without the usual telephoto side effects on perspective and DOF. If so could not whatever is saved by not buying a high end telephoto lens be a decent contribution towards the price of an upgrade to an 80MP sensor MFDB? Not to mention less problems with camera move as a result of using a lighweight 80mm instead of a heavy duty telephoto. Plus less weight to carry around in the camera bag etc etc. If this is all true how could anybody afford not to have one?
