  1. Interesting. Never noticed that design element of the S-lenses. The bayonet release button and red dot on the S and SL lenses/bodies are in the same orientation. However, Leica did offset the focal length engraving on the S-lenses and that would definitely help with alignment. The top of the S-lens has the focus distance indicator which is not present on the SL-lenses so the focal length engraving takes its place on SL lenses.
  2. Not sure which 35 lux you have but the ASPH versions had hotspots when shooting in IR. Probably because of the concave front element. I haven’t tried the latest version 28mm elmarit ASPH but the previous version with the clip on hood worked well in IR on the M8.2. It was equivalent to a 35mm FOV and shares the same 39mm filter. If you want to find old threads about IR, just look up the following keywords: M8 IR Hotspot The biggest issue with most lenses for IR is that a fair number of them would produce strong ghosting or hotspots in the middle of the frame due to internal refle
  3. Not sure about Leica but there’s no such logo or feature on Panasonic or Sigma bodies.
  4. I use to shoot a fair bit of photos in IR with the M8.2. I mostly used either Hoya R72 or B+W 092/093 filters. The Hoya R72 produces similar images to the one above and let in a bit more of the deep reds which meant that shutter speeds was comparatively faster than the B+W filters. The darker of the B+W filters (forgot which one) required much longer shutter speeds but produced more greyscale images as compared to the R72 where there’s much more false colour between the red and green channel,
  5. Having shot on M bodies for the last 10 years going back to the M8.2, I’ve always found that mounting an M-lens on an M-body was very intuitive and easy. It only required the red alignment dot on the lens to be lined up with the bayonet unlock button on the body and the lens fits effortlessly. Aligning the red dot to the body can even be done by feel. With the L-mount lenses, I’ve found it a lot less intuitive, even though the process is identical. Granted, I don’t have nearly as much muscle memory for swapping L-mount lenses as compared to M-lenses but I’ve been having a hard time aligni
  6. This was taken with the 24mm 3.8 as well:
  7. The fact that 2 of the 3 options you listed includes the SL suggests you’re fine with the performance of the SL and do not need the higher ISO performance or IBIS of the SL2-S. The fact that 2 of the 3 options explicitly mentions the 45mm and 50mm suggests that you primarily care shooting with a standard focal length. With those two points in mind, it boils down to budget and the rendering you want to achieve. The 50 APO SL has a very unique rendering, but so do other M lenses of various vintages. I think a better question to ask yourself is what do you want your end-game kit to
  8. No doubt this is the entire design paradigm of the SL system. Peter Karbe has confirmed this in the past. It is a performance focused platform where size/weight constraints are secondary to performance and cost in order to achieve highest performance at a price point that the market will still accept. Peter Karbe himself has mentioned that although the S system as a whole delivers higher performance than the SL zooms, the APO Summicron SL primes supersedes the performance of the S system. The SL APO primes will deliver medium format resolution in a 35mm image circle. So as sensor technolo
  9. Has anyone compared the optical design of the Leica/Sigma 24-70 and Leica 24-90? The front 7 elements are nearly identical. I’ve mentioned this elsewhere before but I’ll repeat. Sigma has patents on lens design dating back to around 2010 that has nearly identical front 7 elements as well. That to me looks like even the 24-90 design was originated at least to some degree with Sigma. It has Sigma’s fingerprints all over it. It’s not to say it’s good or bad, it’s just what it is. The other two SL zooms were licensed design from Panasonic and Konica-Minolta so it would not come as a surp
  10. Isn’t that just the 16-35mm Super-Vario-Elmar? Unless you mean f/4 primes? The Sigma 24/3.5 is astoundingly good when stopped down to f/5.6. Unless you’re trying to achieve that large aperture creamy, low contrast bokeh with a wide angle, there’s really no reason to get a 24mm APO Summicron SL. I shared a 100 MP multi-shot example with crops here (post #16)
  11. Have you tried performing a factory reset and/or updating to the latest FW version? Dim EVF could be because of the EVF display setting. I’m not familiar with the SL but the SL2-S has options for various brightness settings and also offer an ‘Auto’ option. EVF flicker while AF. It would be good to know what AF mode you were using (i.e. AFs, AFc, iAF, etc…).
  12. Problem with the M10 Nitecore charger is that after the batteries are fully charged, rather than just cutting off the circuit, it will start discharging one of them. The longer you leave it, the more it will discharge. This is a design flaw.
  13. BSI will provide about 1 stop improvement in noise, all things being equal. Going from 40 MP to 60 MP will typically reduce the pixel’s photo sensitive area by about half. So they’ll probably cancel out any improvement in noise between each other. So barring any other additional improvements in noise from the sensor technology from other design aspects, we’ll probably see very similar noise performance to the M10-R, or at best maybe 1/2 to 1 stop in noise performance. All that being said, at 60MP, without IBIS, I’d be more concerned about shutter speed and hand holding in low light, even
  14. I got the impression that Leica had a lot of complaints about their SL lens lineup being too heavy when they released the first 3 zooms, plus the 50mm Summilux SL. Ever since then, they have only announced/released much smaller and/or lighter lenses like the APO Summicron SL line and the recent 24-70mm SL, all weighing less than 1kg. I also got the impression that Leica had a hard time selling the 50mm Summilux SL after the initial demand tapered off, which was why it was bundled with the SL2 for a while before the 24-70mm was released.
