dkCambridgeshire Posted September 24, 2018 Share #221 Posted September 24, 2018 Advertisement (gone after registration) The SL system 'no SL long tele primes' policy now makes sense if Leica was waiting for Sigma to 'get on board' … and Zenit could also be queueing to 'get on board' too. dunk Link to post Share on other sites More sharing options...
Advertisement Posted September 24, 2018 Posted September 24, 2018 Hi dkCambridgeshire, Take a look here New Panasonic Full Frame with SL Mount?. I'm sure you'll find what you were looking for!
helged Posted September 24, 2018 Share #222 Posted September 24, 2018 (edited) It all fits well with Dr Kaufman's statement on the Lula-video regarding the potential of the L-mount: "This mount has lots more opportunities and you will see something next year...June 2018." substitute June with September, and viola!

hiepphotog Posted September 24, 2018 Share #223 Posted September 24, 2018 rumor has it that Sigma already makes the TL lenses. IF, if, if that's true, that's pretty impressive, given how sharp they are. you meant the same stuff they have been making for Sony, Fuji and m43? 1 Link to post Share on other sites More sharing options...

IF, if, if that's true, that's pretty impressive, given how sharp they are. I've seen someone suggest that before. Do you have a source? I searched a few days ago, but couldn't find any info about Sigma making anything for Leica. The Sigma art line has a distinct reputation for corner to corner sharpness. People that buy them swear by them. However, there are reports that Sigma lenses lack micro-contrast. I've never shot with one.

sillbeers15 Posted September 25, 2018 Share #228 Posted September 25, 2018 Leica S3 has already appear in Leica Chinese website (for China market),..that is if you can understand Chinese language. I see nothing about Lmount as yet. Link to post Share on other sites More sharing options...

mmradman Posted September 25, 2018 Share #230 Posted September 25, 2018 Some of those L O N G Sigma lenses are not exactly state of the art. dunk Probably, never owned Sigma lens myself. I think later Art lens are better than older offerings.On a side note there is solution to using quality long prime with AF, image stabilisation and mirrorless - Nikon Z6/7.

Jon Warwick Posted September 25, 2018 Share #234 Posted September 25, 2018 Assuming any of this occurs, is it likely that optical performance of a Leica SL lens would be the same on one of the rumoured Panasonic bodies as it would be on an SL body? I’m trying to figure out how optimisation of the interplay of lens + sensor components could impact the output. Does the design of an SL lens likely allow them to be more readily interchangeable across sensors (compared to M lenses that need specific sensor microlenses)?

jaapv Posted September 25, 2018 Share #235 Posted September 25, 2018 Lens performance across the brands should not be a problem, as the whole issue depends on the register distance of the lens, which dictates optical design. However, it would become interesting if different brands use different sensors for their cameras. We could be changing bodies like we used to change film 2 Link to post Share on other sites More sharing options...

HI There Jon They should certainly perform as well, remember, Panasonic have had a long co-operation with Panasonic, and that probably extends to the SL. M lenses need specific sensors (more especially with thin coverglass) because of the angle of incidence of light on the sensor. No such problems with the SL/TL lenses 1 Link to post Share on other sites More sharing options...
lct Posted September 25, 2018 Share #238 Posted September 25, 2018 Which lenses? Guessing R but far past suggests M? Never heard of Sigma designing or building M lenses so far. As for R lenses, the R 28-70 (11265) was designed and built by Sigma i believe. It is the only one i know of but i may be wrong. Link to post Share on other sites More sharing options...

I've never shot with one. ...... ah ..... the mythical 'micro-contrast' ....... which appears to be a term solely used by photographers and refers to ordinary contrast sprinkled with fairy dust. The few SIgma Arts I have used seem plenty contrasty enough for me. The 135/1.8 Art image quality is impressive ..... albeit a lump and weight of true SL lens proportions ........

wattsy Posted September 25, 2018 Share #240 Posted September 25, 2018 (edited) Lens performance across the brands should not be a problem, as the whole issue depends on the register distance of the lens, which dictates optical design. It also depends of course on the camera being able to make the correct internal digital corrections for distortion, vignetting, etc. As we all know, the resulting high image quality from S and L lenses results from a balance of optical design and in-camera digital correction. Presumably, the collaboration (partnership or whatever it is) will involve the sharing of this data so that an SL lens can be used on a Pansonic body without loss of quality.
