Today , checking out my Sony A290 with old Minolta 35/80 f4 so I can set 35 or 50 [ shown on the lens ] to decide which prime to buy for a possible new Sony A35 .
Usually the G1 with zoom plus CV 35 f 2.5 * , sometimes Contax adapted emMa 8 with Helios or J8 * .
* I Like the nom 67mm crop of the M8 and 70mm of a 35 on 4/3rds , but consider that the 75mm nominal offered by a 50 on aps.c may be just a touch too long for everyday use .
