kokoshawnuff Posted May 11, 2012 Share #21 Â Posted May 11, 2012 Advertisement (gone after registration) Puts says the the Marco Elmar 90 is as close to APO Leica gets without actually confirming it (writing the letters "APO" on the box) as such. I'm sure the new summicron meets the Leica standard as APO (a standard Puts says is quite high), but that doesn't mean the APO designation necessarily changes anything except the price.

Double Negative Posted May 12, 2012 Share #22 Â Posted May 12, 2012 The 50 Summilux ASPH is partially APO corrected. Link to post Share on other sites More sharing options...
adan Posted May 12, 2012 Share #23 Â Posted May 12, 2012 I find myself agreeing with both Lars and 01af. Primarily because there are at least two kinds of CA. Â Longitudinal CA - colored light focusing at different points - is the primary target of APO correction. And is more obvious and more urgently in need of correction with longer focal lengths, since it scales with image size. Â Wide-angles tend to be plagued more with lateral CA - those purple/green or yellow/blue fringes in twigs and such in the corners of WA pictures. Whereas the longitudinal CA scales down with the wider field of view and is most pictures made with a 35 or wider is invisible. Â So CA is a problem for all lenses (01af) - but APO correction is primarily usefully applied more to long lenses (Lars). Â One need only look at the order in which Leica has introduced "APO" corrections to lenses. They didn't start with a 21mm lens and work up. They began with the 180mm APO-Telyt-R. Then the 400 f/2.8. In the M system, Leica also started applying APO corrections where they were most needed, at the long end, and worked their way down. 135>90>75>50 Link to post Share on other sites More sharing options...
sparkie Posted May 12, 2012 Share #24 Â Posted May 12, 2012 90/2.0 ASPH APO has been out since 1998... one of the first to receive the 'APO' designation.. Link to post Share on other sites More sharing options...
Studio58 Posted May 12, 2012 Share #25 Â Posted May 12, 2012 I'll just enjoy my 75mm/2, a stunning lens which was a bargain by comparison. Â I picked up the 75 APO recently in like new condition for $2,750...... Is sounding like an absolute steal now Link to post Share on other sites More sharing options...
jaapv Posted May 12, 2012 Share #26 Â Posted May 12, 2012 However what really looks funny is the flipping inscription on the new Apo-Summicron-M 50 mm Asph's front ring. I thought we left behind this ugly nonsense decades ago. Yuck! I agree. It is extremely impractical that we have to use the camera upside down to get the best image quality with this lens.

Sp12 Posted May 12, 2012 Share #28 Â Posted May 12, 2012 Isn't the 50 Summilux ASPH also Apochromatic? Â Sort-of-depends on your definition. It's very good. Link to post Share on other sites More sharing options...
haroldp Posted May 12, 2012 Share #29 Â Posted May 12, 2012 I agree. It is extremely impractical that we have to use the camera upside down to get the best image quality with this lens. Â When the picture looks upside down, I stand on my head. It requires excellent balance to the focus and shoot. Â Gravity does get confusing.

hoppyman Posted May 12, 2012 Share #30  Posted May 12, 2012 Thorsten Overgaard has made some interesting remarks on his "what if" page regarding possible new lenses (written prior to the May 10 announcements). You can read them just under his very fine portrait of Peter Karbe  http://overgaard.dk/leica-M10-digital-rangefinder-camera-page-Leica-M10-Monochrome-Digital-Rangefinder.html Link to post Share on other sites More sharing options...
rramesh Posted May 13, 2012 Share #31 Â Posted May 13, 2012 I think Leica should just have a 2K range, 4K range, 7K range, 10K range and priceless of lenses. Link to post Share on other sites More sharing options...
IWC Doppel Posted May 13, 2012 Share #32  Posted May 13, 2012 Seems APO will be the new ASPH. It's one abberation that's been proactively corrected. I'll dust off an Erwin manual and see what else we might add to lens acronyms in the future  It will only be 50mm + very fast glass as room for lettering could be a problem....  Reminds me of the 80's HiFi market, they were incredible at offering somethng you didn't know you needed and making it a must have  Still interested in what the images will look like, if and when the 35 comes out I wonder how close the pricing will be to the Nocti..... F2 is not really fast enough for shooting people indoors at night with the 9 IMO. I wonder if the M10 will add 1-2 stops in ISO performance making the need for luxes and the Nocti depth of field only ?  Sorry to ramble it must be the excitement Link to post Share on other sites More sharing options...
