From Peter Blaise - Re[1]: Konica Minolta Sony Alpha/Dynax/Maxxum 5D/7D/A100 lens adapter for older Minolta SR/MC/MD/X-600 lenses

Hi G..W..,
See the green box at http://www.geocities.com/peterblaise/minoltamf (copied below *) which
discusses Minolta-brand 2x teleconverting adapters, non-Minolta-brand 1.1x+ teleconverting
adapters, and Tamron Adaptall non-teleconverting (yeah!) adapters only for Tamron-brand
adaptall lenses. Of course, on a new Konica Minolta or Sony DSLR, the old non-Tamron-Adaptall
Minolta SR/MC/MD/X-600 lenses will be manual focus, manual stop down metering, and will have
not only the camera's 1/1.53x crop factor, but also the 1.1x-2x teleconverting adapter
magnification, so a 50mm lens will be at least 1.53 x 1.1 = ~84mm and as much as 1.53 x 2 =
153mm - NOT the normal expectation from our fine Minolta old SR/MC/MD/X-600 lenses, eh? My
17mm captures a 52mm lens's angle of view - WAAAH! I might as well use the kit zoom and be
happy! :-(
Anything else I can do, lemme know!

* This needs updating for 1/1.53x crop factor in digital cameras, but have at it:

Minolta MF lenses on AF cameras?
A frequent inquiry:

Yes, Minolta made two 2x teleconverter adapters of superlative optical qualities to fit
Minolta manual focus lenses onto Minolta AF cameras, one for under 300mm lenses (S) and one for
over 300mm lenses (L). Look for these Minolta brand descriptions and part numbers:
Minolta 2x M/A CONVERTER-S 2583-107
... and ...
Minolta 2x M/A CONVERTER-L 2584-107
Use http://www.google.com/ to search for sources, ignore the responses that claim to take
your order and let you know when it is back in stock - they are search engine spam. The price
range is new ~US$350 or so, to used at whatever anyone thinks it's worth - NOT a popular or
fast moving item.
Like all lens adapters, they may or may not physically fit a particular lens, and like all
adapters, they may or may not degrade the image forming qualities of a lens below your own
standards. Be prepared to "buy it and try it". Other manufacturer's made ~1.1x to ~1.6x
teleconverter adapters of varying optical qualities to fit Minolta manual focus lenses to
Minolta auto focus cameras, as you were sent to on eBay to see, and Sigma made one that even
auto focuses when used on the Minolta AF series cameras - the 5000/7000/9000 (but NOT on later
series Minolta auto focus cameras).
http://www.srbfilm.co.uk/ is a reliable place to purchase new adapters on demand to fit
your wonderful Minolta manual focus lenses to just about anything, or to fit just about any
lens to a Minolta manual focus camera, including reverse adapters and filter rings for reversed
Minolta manual focus lenses.
Note that when any lens is fitted to another camera, almost all auto features are not
implemented, and all lenses become manual focus, manual stop down metering, and often have a
different focal length and different maximum aperture due to needing a teleconverter to
accommodate the different distances from the lens mount to the film for each camera system.
Tamron is the only exception to this with their Adaptall 2 series of lenses which fit all
Minolta 35mm SLR cameras, manual and auto focus, with adapters that have NO teleconverter
effect, though they do loose their auto aperture operation on auto focus cameras and become
manual stop down metering lenses. See http://www.tamron.com/lenses/prod/adaptall.asp for their
modern series of Minolta-fit manual focus lenses. If you are planning on one set of lenses to
use on different manufacturer's camera bodies, this is the only way to go.
However, most people prefer the benefits of fully functional features from their investment
in Minolta-fit manual focus lenses, so they eventually settle down on a matching Minolta manual
focus camera body for them, especially when they realize that there is usually a teleconverter
effect, and the loss of automatic features, when adapting lenses to fit between different
camera body styles, and so they just "settle" on an inexpensive Minolta manual focus camera to
use with their Minolta manual focus lenses, and do not try to use such lenses elsewhere.
Tell me more about what you are after!
