microview Posted June 2, 2010 Share #1 Posted June 2, 2010 Advertisement (gone after registration) Leica Mayfair has a sample of the new lens which one is allowed to take (mounted on camera!) a step or two outside their street door, which an assistant holds open for you to take a few pics. (This is apparently for insurance purposes.) The weight of the lens in comfortable in the hand and on the M9; focus and aperture changes are smooth and it's a fine piece of engineering. It was a bright, sunny morning and obviously image quality is excellent. However, in these two similar shots the purple fringe running down the black lamp-post and the fringing to the lead dressing under the window and the frame itself against the glass [enlarged portions superimposed] are not what I would expect to see with a £3k+ lens. Comparison images I took a few minutes later with my own v4 Summicron don't have these artefacts. FWIW the Mayfair store will add your name to a waiting list (four at present) but will not take a deposit (as it did when the M9 itself was announced), and so if the VAT is increased before supplies become available one would have to pay at the increased rate.

Advertisement Posted June 2, 2010 Posted June 2, 2010 Hi microview, Take a look here New 35 Summilux – a concern. I'm sure you'll find what you were looking for!
microview Posted June 2, 2010 Author Share #2 Posted June 2, 2010 And here's the v4 Summicron..... But they all look terrible here, so give a poor representation of the actual files!

rosuna Posted June 2, 2010 Share #4 Posted June 2, 2010 I am not sure purple fringe is due to the lens itself, or not to it alone. Sensor filters may contribute to the problem to a large extent. Link to post Share on other sites More sharing options...

Sensor filters may contribute to the problem to a large extent. Well, I did experience a similar fringing recently with a brand new 35 Summicron with some black metal rods against an extremely brightly lit background. (Incidentally my as-new v4 turned up at a dealer's just a week after I'd shelled out £1850 for the ASPH. And I very much preferred the v4. Bad timing!)

adan Posted June 2, 2010 Share #7 Posted June 2, 2010 Advertisement (gone after registration) It is my impression that Leica's new ASPH designs often have more lateral chromatic aberration, and also very "hot" highlights - both of which can lead to purple fringes. Which is not a criticism - they have improved performance in other ways, and optical design is alway a trade-off between different kinds of flaws. I was investigating red-edge differences between my 1983 pre-ASPH 21 Elmarit, and the current 21 Elmarit ASPH, and noticed how much more green/magenta CA and contrast the 21 ASPH has (although it also shows better definition of the thinnest branches in these crops from the left edge of the frame). (EXAMPLE: M9, f/5.6) I've noticed the same with the 28 Elmarit-ASPH vs. my 28 Elmarit v.3 (also 1983 vintage) - the ASPH has better definition near the edges and corners, but also more lateral CA. But as Ruben says - the optics of digital sensors (microlenses and the cover glass) can add their own effects. The OP's purple edges look fairly typical of strong highlight/shadow edges - amplified by a lens with strong edge contrast - in digital imaging. Not to jump on the OP - but there is no such thing as a perfect lens. Not for $5,000 - not for $50,000. A 35 f/1.4 is a rather extreme optical design, especially fitted into the volume of the M lens. Compare its size - and its RELATIVE performance - to SLR 35 f/1.4s (Leica R, Canon - or if you really want some fun, the Nikkor AIS 35 f/1.4). Then come back and let us know if the RELATIVE performance difference is worth the RELATIVE price difference. It is quite possible that it isn't - for any given photographer. Then again - maybe it is. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

ho_co Posted June 3, 2010 Share #8 Posted June 3, 2010 Only one thing to add: Try a different RAW converter as well. Some of them mask the digital artifacts better than others. Link to post Share on other sites More sharing options...
zlatkob Posted June 3, 2010 Share #9 Posted June 3, 2010 I'm not sure, but that's probably well-within normal. This is from the previous (1994 design) Summilux at about f/1.7 (100% crop). This plant is not purple/magenta. For some images, the defringe setting in Adobe Camera Raw will help. Otherwise, it may require making a selection in Photoshop and desaturating the magenta.
