bocaburger Posted June 23, 2014 Share #1 Posted June 23, 2014 Advertisement (gone after registration) Well my Novoflex adapter came, and lo and behold it is coded. (Oddly the pits are round as if done with the end of a drill, unlike in official pics of the Novoflex adapter ...so maybe it's a counterfeit and I got ripped off for $150 but it's made beautifully and works perfectly and I saved almost half). So to my question: does setting an R lens in the menu do anything other than impart informational data to EXIF as to what lens was used? That is, will the firmware apply any corrections? Specifically distortion and/or chromatic aberration? Reason I ask is I have the chance to pick up a 70-210 f/4 (E60 filter) for a pittance (~$200). I had that lens back in the day and it was quite sharp/contrasty, and reasonably-sized/weighted to handle on a smallish body. I see it's not on the menu, but the 80-200 f/4 is. According to the specs for the latter, it has 2% distortion at both ends, whereas the 70-210 has 3%. So using the 80-200 setting if I'd be left with 1%, that would still be a significant improvement. PS I could not find this in any searches I did, but if it is specifically answered elsewhere would appreciate a link. Thanks. Link to post Share on other sites More sharing options...

thighslapper Posted June 23, 2014 Share #2 Posted June 23, 2014 There has never been any mention of lens corrections applied to anything attached to the R-M adapter. Because of the different optical design none of the corrections needed for the wider M lenses are necessary. Anyway, as far as I am aware, M lens corrections are limited to vignetting and peripheral colour casts..... You just have the convenience of the lens being named on the EXIF.

JohnJWhite Posted June 23, 2014 Share #3 Posted June 23, 2014 Right. With the elements far enough away from the film plane to clear the flapping mirror of an SLR, the photons are hitting the sensor at close enough to perpendicular to not need any corrections.

bocaburger Posted June 23, 2014 Author Share #4 Posted June 23, 2014 I was under the impression that Nikon and Canon DSLRs correct for chromatic aberration and distortion of lenses. Link to post Share on other sites More sharing options...
chris_tribble Posted June 24, 2014 Share #5 Posted June 24, 2014 I've been falling in love with the R 80-200 f4. Given that high ISO is so much less of a problem on the M than on the M9 + that the tripod mount on the Leica R-M adaptor makes working with a monopod a real pleasure, I've been very encouraged by recent results. Up until now I'd have been using a 5D2 + L 70-200 2.8 IS lens for this kind of work. However, as I didn't have that with me for the shoot I was doing, but did have the 80-200, I gave it ago. The image below is of the painter Winifred Nicholson's grand-daughter (Raf) who was giving a presentation at a workshop I was covering for Lakeland Arts Foundation (talking about the painting in the background). I hadn't realised I'd dropped to 1/45th for this shot (most images were at around 1/125th - but it's pleasingly sharp under the circumstances + I really like the way the lens renders the colours. I'd strongly encourage playing with this lens. For contexts when you can work in a considered way, it has real advantages. Welcome, dear visitor!

jaapv Posted June 24, 2014 Share #6 Posted June 24, 2014 I had this lens in the past, Chris, and found it amazingly flare-free compared to other zooms, with good clarity. I did get one again recently, and after a CLA I'll give it a whirl. . Link to post Share on other sites More sharing options...
bocaburger Posted June 24, 2014 Author Share #7 Posted June 24, 2014 Advertisement (gone after registration) I owned both (70-210/4 and 80-200/4) in my days with the R system. I honestly was disappointed after spending the money to trade up, that the newer lens didn't exceed the older one optically by anywhere near as much as the online hype promised. The 80-200/4 is still selling in the $1000 range whereas I could snag this 70-210 for less than a quarter of that. It still suffers from the stigma of being a Minolta design. The 80-200 is also 300g heavier, and my Novoflex R-M adapter does not have a tripod collar. My only other R lens is the 400/6.8 which has its own tripod attachment.

satijntje Posted June 24, 2014 Share #8 Posted June 24, 2014 The 80-200 mm f4 is indeed an amazing Lens. Prices went up by nearly 50% during the Last 12 months.

jip Posted June 28, 2014 Share #9 Posted June 28, 2014 The camera does not do anything with the images from the R lenses appart from give them the correct EXIF data... so when importing them in Lightroom, you can easily click the profile and it is fixed Link to post Share on other sites More sharing options...
masjah Posted June 28, 2014 Share #10 Posted June 28, 2014 The camera does not do anything with the images from the R lenses appart from give them the correct EXIF data... so when importing them in Lightroom, you can easily click the profile and it is fixed To quote from the Leica R Adapter-M instructions: "When using some Leica R lenses, you can enter the lens type in the menu. This guarantees an optimum picture quality and ensures that the lens data is written to the relevant EXIF file for the pictures. ...... " (My italics.) To me this implies that something more than writing EXIF data is being done (I suspect a bit of vignetting correction on .jpg images). Link to post Share on other sites More sharing options...
jip Posted June 28, 2014 Share #11 Posted June 28, 2014 (I suspect a bit of vignetting correction on .jpg images). That is why I have not noticed it I think. I never shoot pictures in JPEG because I compared the results of the non selected lens with a selected lens with the summilux-R 80 mm. The only difference I saw was the exif data.
