I had ask a question about setting up a test to compare these two cameras. My initial expectations was for the Hasselblad 500c/m w/ 80mm f/2.8 lens to show a superior result compared to an RB67 w/90mm f/3.8 Sekor C lens I was somewhat surprised to find that there was differences in favor of both?? Here is the test set up. the test shots were made at the same time, one camera after the other using as close to the same exposure as possible. The shutter speeds of the two lenses differ a bit. And also a cloud may come by and the reading to get the same "0" meter reading might change. I used a tripod and bothe cameras were fitted with a quick relase plate so I could easily change the two cameras out without moving the tripod or changing the angles. I used Kodak Tmax 400 developed in XTOL 1:1. Both rolls of film were process at the same time and fresh one shot XTOL 1:1 was used for each roll in a small "patterson" type hand tank. On a side note I found that Tmax in XTOL was really nice and something I will try again. I don't normally shoot Tmax. The negatives were scaned on an Epson V500 scanner using a Vista 64 bit PC. No dust removal, sharpening, or any other Photoshop alterations were made. I cropped one of the shots so that the format difference was hidden so as not to give away which shot came from which camera. The shots were only re-sized to comply with the posting rules here. I can only post 3 shots so I want to post them together. I will try again later to post two more shots. Can you tell the difference? which shots do you like best?
