Hi IG
I have a XE7 and would fully agree with sitemistic. It is a very well built camera and very reliable too. And it is heavy - about 750 gramms without lens. It is my workhorse SLR. The mirror slap is a little bit louder than at the R3 but this is also depending on the maintenence of the camera. The finder on the R3 is much brighter but the XE7 finder is (for me) absolutely sufficient in low light situations, never had any problems.
I have made wonderful slides with this gear and Ektachrom 64 film. Because of the metering mode of the XE7 you have to underexpose Ekta 64 by 1/3 f-stop. BTW I have a very rare lens for the Minolta MC/MD mount, it´s a 2,8/24mm VFC wideangle. I is specially made for architecture and landscape shots. The days I have bought it, it was very expensive (for me) and I have collected money about two years untill I could afford one.
The XD11/XD9 or the X700 are wonderful cameras too, but for me, they have too much electronic parts inside wich can fail or brake down.
Please forget the fairytale is told of the R3/XE7. The only part they have both is the copal shutter. There was only a joint-venture of Leitz an Minolta in developing a modern SLR in the early 70-s.
