hello, i would like to throw my 2 cents in, although it reflects what everyone else has already said. my first camera was a minolta x370 that someone gave me. i then switched to an autofocus canon eos elan 7e but sold it because it failed in my naive expectations that it would make better pictures. (hence, they got worse) recently, i went back to minolta md / x - series manual. and yes, i deliberately switched back, not just circumstance this time, my lovely wife even gave me the green light to buy any camera i wanted. Here is the great minolta gear i have accumulated over the past year: body: x-570, 24mm 2.8 md, 35mm 2.8 md. 50mm 1.7 md, 85mm 2 md, 135mm 2.8 md, a 360px flash, an autowinder.
seriously, all of these lenses are among the best of their type ever made by any manufacturer. im especially impressed with my cheapest lens, (well, beside the 50mm) that is the 135mm, it is unusually sharp. i also am very impressed with the flash capability, even though it is "old" ttl, its exposure accuracy is on par with my (previous) canon eos elan 7e. the body is very easy and fast to use in manual mode (because the aperture, shutter, and recommended metering is shown in the viewfinder) and the meter is very accurate. in fact, the meter is so good, that i often kick myself for overcompensating and making bad exposures when i dont trust the meter as much as i should.
i recommend the x570 over the x700 or any other minolta. however, these two are almost identical. the x700's program mode is good, but totally misses the point of using this kind of camera. it was advanced in its day but the program mode is sort of useless now for anyone who knows how to use a camera. yes, all md / mc lenses are useable on x series cameras, except for some really obscure and expensive ones that you'll probably never buy. mc stands for "metered coupling" which basically was Minolta's version of "full aperture metering", so yes, full aperture metering is exactly what they do. i believe the most recent md lenses have improved coatings, more plastic in their construction, and upgraded optical designs over their mc counterparts. but i dont think this will make any difference in the quality of your images. go for whatever your wallet allows
as for durability, the x series are still serviceable. even if you do break a body, they are plentiful and cheap on ebay. if you decide to go with minolta, your pictures will be as good as they can be, your lenses will last forever, and you will have some money left over to take your loved-one out for a nice dinner. minolta makes everyone happy.
