FrankA Posted February 14, 2010 Share #1 Posted February 14, 2010 Advertisement (gone after registration) Are these the same design, just r vs m, or are they different? Can you explain the differences? Canadian vs Germany? Interested in rendering and resolution qualities. Thanks, Frank Link to post Share on other sites More sharing options...

adan Posted February 14, 2010 Share #2 Posted February 14, 2010 They are similar enough that Erwin Puts lumps them together in his Lens Compendium review as regards overall contrast, flare tendencies, coma correction. He says the 80mm holds up very slightly better in the corners @ f/1.4 and f/2 but that "these differences would probably be lost in everyday picture taking." Same basic optical layout - 7-Element, 5 group modified double-gauss - the 80 has slightly thicker first and sixth elements, the 75 slightly thicker 2nd and 3rd. He rates the 80mm R as about even with the 90mm R f/2 (preAPO), but rates the 75mm M as having "a clear edge" on the 90mm M f/2 (preAPO) until f/4. Both were Canadian-made originally, with production moving to Germany in the mid/late 80's. The 75mm got a barrel (but not glass) redesign to cut weight at some point, so German lenses from the last decade or so are lighter than the Canadians. Very early Canadian versions of the 75 had a separate bayonet-mount lens shade. Within a year or so (at least by 1982) the shade was built-in.

cpclee Posted February 14, 2010 Share #3 Posted February 14, 2010 The optical differences aside, the M version is going to be a lot harder to use in practice. With the extremely shallow depth of field at wider apertures, the focus-and-recompose approach for off-center subjects will fail to work. Link to post Share on other sites More sharing options...

It became my favourite and I don't find it so difficult to handle. Link to post Share on other sites More sharing options...

Do you actually own the 75 lux? Link to post Share on other sites More sharing options...
topoxforddoc Posted February 18, 2010 Share #7 Posted February 18, 2010 Advertisement (gone after registration) I love both my 75 M lux and my 80 R lux. Both draw in the same way with soft OOF highlights. Very flattering as portrait lenses, but they sharpen up once stooped down a bit. Link to post Share on other sites More sharing options...

biglouis Posted February 18, 2010 Share #9 Posted February 18, 2010 Having seen some examples in the forum of the 80-R on full-frame bodies I will definitely own the combination one day. They are always outstanding. Link to post Share on other sites More sharing options...

They are always outstanding. It's pretty great on a cropped body (DMR) too The 80 R lux is one of my favourite R lens. If anything, the M75 Lux is a little higher contrast wide open (where the 80 has smoother contrast); other than that, they're very very similar overall.

So would i but pebbleplace.com are not sure if it fits the 5D. The pre-apo 90/2 R is a great lens though. My favourite 90 so far. Link to post Share on other sites More sharing options...
farnz Posted February 23, 2010 Share #12 Posted February 23, 2010 So would i but pebbleplace.com are not sure if it fits the 5D. ... LCT, I use mine on my 5D2, although I bought it after I'd shaved the mirror for my 19 Elmarit II so I can't tell you if it interferes with the mirror return. (Shaving the mirror is surprisingly easy though. ) Pete. Link to post Share on other sites More sharing options...

psquared Posted February 25, 2010 Share #14 Posted February 25, 2010 I have used my unmodified 80 lux on 5D and 5DM2 with no problems. And, my cameras have not been modified. Link to post Share on other sites More sharing options...

Yes there are variances in the mirror box of the 5D. Some bodies fit and others don't for clearance reasons. The only way to check it out is to test the lens in person i'm afraid.
