    Minolta MD 50mm f/1.7 vs. f/1.4

    Just picked up a free Minolta X-700 with a 35-70 zoom on it. It looks like it needs an MD series lens for priority auto exposure. Can anyone tell me the functional differences between the f/1.7 and f/1.4 lenses? I'm a Canon guy, so I know why their FD f/1.4 is much better than the f/1.8.

    In the Minolta lineup, they are both sharp lenses. Occasionally you will even see a f1.7 that edges out a f1.4 version for sharpness, they are that close. However, the bokeh is noticeably better on the f1.4 to my eyes. Take a look at Antony's lens tests at www.rokkorfiles.com and check out his 50mm shootout.
    Also, you don't "need" an MD lens, what you're referring to will usually work with all the lenses. My favorite series was the MD RokkorX though. The more advanced MD coatings, with the build quality of the all metal MC series - best of both worlds! ;-)

    Thanks for that info. The manual seems to suggest that the MD lens gives both program and aperture priority, while the MC lens only gives aperture priority. Is this an incorrect assessment?

    The MD-lenses had a modified aperture operating system with a linear and exact relation between the operating way and the f-stop and a faster closing of the aperture blades. This was necessary for the first multi-automat SLR, the XD-7 (XD-11) and the following generation of XD, X- and XG-cameras.

    The 1.4 will give slightly less DOF when focused close and will give you a vastly increased price tag. The only reason to buy a 1.4 is to have the ability to say that you have a 1.4.
    Thank you.

    The other tangible, is that the 1.7 is while almost as fast as the 1.4, it is not as heavy, so you are more tempted to keep it and the x700 with you every day in your day bag.

    I have shot an x-700 (actually a few different ones) since they were first introduced, and find that I use P mode very rarely. I find A suits my style much more readily. Manual metering in the x-700 kind of sucks. For a much more pleasant metering and selected speed though the viewfinder indicators, look to find a close relative, the X-570.

    As others have noted, unless P is the needed mode, older MC and Roccor-X lenses work fine. They are, being all metal, quite a bit heavier too.
    my real name, imagine that.

    Well, like I say, I don't know much about the Minolta's but with Canon's FD 50mm lenses, the f/1.4 has 6 elements vs. 5 in the f/1.8 and it has an 8-blade aperture vs. 5 blades in the f/1.8. The f/1.4 lens is substantially better in terms of its optical qualities.

    No, the MC supports aperture priority and the MD supports both aperture and shutter priority, as well a program.

    What's the difference between Rokkor and Rokkor X?

    I think that assuming that in the event that every example of these lenses performed exactly the same when they were manufactured after twenty odd years use and abuse in some cases, who knows if each example will give the same results.
