I recently bought a Minolta Maxxum 5D digital reflex. For many years, I used a Minolta SRT101 and a Mamaya-Sekor DTL500. The Mamaya took the so-called Universal Screw Mount lenses.
I was able to buy a converter for the screw mount lenses - a Vivitar 135, a Quanteray 70-200 and a Mamaya 50. It seemed to make more sense to try to use the old lenses than spend a bundle on new ones. I like the 18-70 that came with the camera, but it is clearly limited.
I use these lenses in manual mode, setting the lens and shutter by lightmeter and viewing the playback of the first shot or two. This works fairly well - after years of manually focussing and setting these lenses it's not a big hardship (but no match-needle built in meter).
My main problems are with DP Challenge. None of these lenses are listed on the database, so I can't add them to my profile. More to the point, I can't find a way to list the 135 on my current entry to Bokeh II. Also, since the lens is not electrically connected to the camera, the lens opening defaults to f/1.0 on the EXIF data (not the f/3.5 actually used).
I'm pretty sure I can't do anything about the EXIF data, certainly not on the shots already taken. Is there a way to list a lens not in the database on my profile? Is there a way to list a lens not on my profile or in the data base on the submission? And, if asked for the EXIF data, how do I square the F/1.0 indicated with the actual f/3.5 used in the shot? |
