Hello Marcus,
I have used Minolta equipment extensively from the manual focus days until now. The Maxxum 9 is hands down, one of the best 35mm SLR cameras ever made. Even the Canon and Nikon guys will grudgingly (and often admirably) admit it. If you are in the market for this class of camera, the only other camera I would consider for the ergonomics is the Nikon F6. When Nikon introduced the F6, someone once joked, "Glad to see Nikon finally made a Maxxum 9 and put a Nikon lens mount on it!" (Just a funny, but you get the idea.)
Whatever you do, don't listen to the shutter sound UNLESS you want to buy one! Hehe...that shutter is a blend of exotic materials, and hits 1/12,000th of a sec. Sounds like pure butter. The Maxxum 9 is built like a tank. I have heard several stories of these cameras falling 6 feet or more onto rocks or concrete; the photographer cries a little, then picks it up and continues the shoot without a hiccup! I know from experience, dropping a 7 body (or any other amateur body) like that results in an inoperable camera. The 9 has a huge grip, viewfinder is wonderfully bright and clear; autofocus is softer sounding than some other cameras; the focus motor is bigger and more "torque" so less of a high-pitched whine, more like a lower sounding "whirrr". It is weather sealed (moisture / dust resistant seals all around the camera), and the pop-up flash is a useful feature because it can wirelessly trigger off camera Minolta flashes. Truly a Pro-body in every way. Shot 5.5 frames per second, I believe - and that's with out a booster. The VC-9 grip is great, but does add weight to an already heavy camera. Well worth it if you like to shoot with rechargeable AA batteries, or if you do a lot of portrait orientation shooting, though.
All that being said, I recently am getting back into photography, and I purchased a 7 body over the 9 again, because it is lighter, smaller, and feels *almost* as good to me with the VC-7 grip attached. Plus the 7 has built-in support for SSM lenses and ADI flash, along with the matrix metering screen on the back which can be really handy if you have the camera up on a tripod. Believe me, with how good the 9 feels in your hand it is a very hard decision between the two, and I cannot emphasize enough how strong the 9 is built. You can still upgrade the 9 body to SSM and ADI flash compatible, but you will have to send the camera to Runtime in Germany for this service. They are the best Minolta service place left in the world.
What other cameras are you considering, and what is your intended purpose with the 9? I will try to be of more help if possible, as I have shot nearly every modern Minolta body at least once...I had quite a collection going back in the day.
Lastly, here is a
link to a short review on the 9.
Also, a
link to my own article about sending a Maxxum 9 to Runtime for the SSM/ADI upgrade a few years ago.
Hope that helps!
