  1. If non continuous AF is what you're looking for switch to MF and use the back button focus method as NickT has described. On the other hand if continuous focus is what you're looking for select either IAF/AFS/AFC and you can still use the back button focus button. Just do not release the back joystick once you've achieved the focus you are looking for and trigger the shutter release button as and when you wish to take the shot. However it will not solve the problem you've described about hunting for focus due to the inappropriate AF focus area. Chances the focus area you've selected is too large compared to your subject therefore the camera AF lands itself on the background or foreground instead of your subject. Try selecting 'single point' to see if it can resolve your problem.
  2. That is Leica poison. The 50mm Noctiluxs are full of character but never perfect. My .95 shows a pronounce CR although it is correctable in LR. The other M lens with the same design is the M21Lux.
  3. I have similar sentiments. Focus on taking the composition and lighting of the pics to the next level certainly is more rewarding than just considering bokeh alone. Enhanced lighting allows the photographer to actively drop the background exposure by 2 stops when controlled enhanced light can expose the subject correctly and it certainly draws viewers' attention to the subject of the pics more than just the effects of bokeh alone.
  4. I agree with you that Leica has a rather weak 3rd party flash maker support mainly due to the low volume of Leica cameras in the market. Rather than Leica placing resource to develop and manage an individual flash protocol, Leica should either take a position taken by XIID on sharing Nikon flash protocol (since the pin positions are common as Leica cameras) or share the same pin configuration and protocol with Panasonic S series cameras since both share the L-mount configuration. I honestly think Leica just has a poor business strategy. On the subject of SF60, it frustrates me as the flash overheats easily and shuts down as I have two units. For the same money, you can buy the more powerful Nissin MG10 (165kWs) just that you need to invest in one unit of SF-C1 Comander (remote trigger) to control it. The MG10 functions and feels very well built. So I use the MG10 as my main light and both SF60s as rim & back lights to support my OCF gear for my SL2 & M10R.
  5. I think in many instances, 'how much' of the bokeh and the way the particular lens renders the 'bokeh falloff' gets very personal. I also agree that 'too often' and 'too much' makes bokeh losses it's shine. Let's not forget the intention of the bokeh is to draw attention to the subject and not get distracted by the background (I hope this is the general rule and no objections by anyone to that?). More often than not when a portrait is created with the right amount of light (soft or hard / single or multiple source at various intensity) together with the application of bokeh or the lack of it (often in a studio), an art piece is created through the lens just as an artist would paint a portrait. The light source or the amount determines the mode of the pics than merely illuminate the subject. Enhanced light through OCF (off camera flashes) isn't a popular topic in this forum that I've observed. Nevertheless the creative element and artistic appeal has a much more impact on a photograph than bokeh in many instances. Also there is much more fun and challenges applying OCF that eventually gets paid off by the results in a good pic.
  6. Welcome back Vikas. Looking at your pics of Bird nest fern recalled my memory of removing one from my yard due to mostiquto breeding problem and removing a bee hive for other reason just earlier this year. Or just spending too much time back home due to the Covid situation.
  7. Due to the nature of physics, the 75 makes creamer bokeh than the 35 compared to based on same subject. I found that the 75 can still make nice bokeh for half to 3 quarter body length subjects while full body length means the distance between photographer & subject increases to the point beyond nice bokeh for me on portrait shots. Therefore the Sigma 105mm f1.4 does have an attraction on me for full body length shots. However I have yet made up my mind over it as I've been seeing sample shots that were not as convincing on some. I still love my SL75.
  8. Great observation you've shared. The only Sigma lens I have is the 150-600mm. Comparing to my SL90-280, the Sigma lens hunts quite a bit more on AFC application. My thoughts were that the focal length is longer compared to my SL90-280 so perhaps that should be the reason. Now matching to your experience on shorter focal length lenses comparison, it is likely that the data points provided by Sigma lenses to the L-mount bodies (DFD on CDAF) could be less compared to Leica SL lenses that results in the additional focus hunting.
  9. I presume both of your shots are taken with the SL Lux fully open. Comparing both of your shots, it shows clearly that for smaller subjects (such as your second shot), a nice bokeh is created. However the bokeh in your first shot is not quiet present. It is all due to the distance between your subject and photographer. For full body length subjects to pop out of the blur background, either a less than F1.2 or a longer focal length lens is required. Even my SL75 is not so great on creating a nice bokeh beyond half length body shots. I kept my M0.95 and APO R180 2.8 although both are manual focus. I am only sharing my personal opinion. Readers do not need to agree with me.
  10. My brief experience handling the Sigma 85mm F1.4 DG DN did not made me feel that the Sigma lens is any slower than my SL75 in acquiring AF. I did not feel it to be any faster than my SL75. However the compact size and light weight of the Sigma lens makes it logical to respond fast in AF (provided the linear motor is not slower).
  11. To be fair software algorithm isn't the strength of Leica. Based on the timeline you've mentioned, it is highly likely the programmers might be outsourced to Asia while keeping a really small team in Germany. It certainly is not an easy task to hire software engineers in Europe comparing to Asia. In Asia, young minds are abundant and cost to hire is way lower especially in India & China.
  12. Yes. Leica certainly did their own GUI (graphic user interface) as it differs greatly from Panasonic and I must say I really like it a lot as a user.
  13. It is good that you have IT background and can share your valuable experiences and opinion with us. It is my assessment coming from the manufacturing management background that Leica AF system is likely wholesale licensed from Panasonic. Leica is only a USD$300mil company. A SME by global definition. It would mean almost impossible to have the resources to design and have it's own AF algorithm & hardware design from scratch. There can be minor tweeks from Leica in GUI of Leica products to differentiate it from Panasonic cameras. However if you look at the number of AF sensors of both Leica & Panasonic, they're identical but very different from Sony & others. I am very sure the face/ body detect AF from Leica & Panasonic is identical. Leica likely do not display the cross over the eye although the sensor does track the eye (only logical to think so). The misses in focusing on the eye should happen equally on both Panasonic & Leica cameras (please tell me otherwise if you have different experiences) as the processing power & speed is the limitation (hardware of IC limitation).
  14. For Leica SL series cameras continuous focusing takes place in every shot irregardless of AFS or AFC settings so long as the drive speed selected is 'medium' or lower. If drive speed 'high' setting is selected, AF is locked on first frame for both AFS & AFC settings (check instruction manual). The difference in AFS & AFC for Leica (only) differs in priority on either AF or triggering the shot (no successful AF garrenty). However in real life, there is little difference in successful AF even when AFS is selected. For successful AF, it is dependable on the AF type selected (single, zone, tracking, face/body,...), lens selected, lighting/contrast available & size of subject that I've experienced.
  15. I am very sure the processing power is key to a reliable continuous AF system. Even the Sony A7 IV's drive speed to shoot continuous RAW drops to 5 frame per sec, 10 frames per sec with continuous AF is only for compressed RAW shows the processing power limitation on the A7IV. Unless there is a limitation to CDAF in continuous AF application which I cannot see at this point, there is no reason why PDAF is more superior over CDAF in continuous AF technology where is sufficient processing power. The Z9 holds a large battery (same as D6) over the small batteries (like any other mirrorless cameras) also signals much energy is required on fast processing. SL2 /S has rolling shutter distortion while electronic shutter is selected. Which makes it useless on capturing fast motion without risk of rolling shutter defects. The Z9 does not have any such distortion. The explanation is on it's fast readout speed from the stacked image sensor solved the problem.
