  1. Thanks for info. I did not notice that phenomenon on AFS. So again it is logical to attribute the blur effect relating to final refinement focusing and EVF refresh rate of Panasonic & Leica. The same contrast detection AF is used in final refinement focusing in other mirrorless Phase detection AF camera but we do not hear about this phenomenon.
  2. Thank you for posting the DFD explanation. Without it, there is focus hunting and it slows down the focusing time. In a mirrorless camera, Phase detect system (it is actually a hybrid of Phase detect to move the focusing to the focus plane desired. However due to the lack of accuracy, the contrast detection actually takes over to finalise the focusing). so as the DFD write out explains, the normal contrast detection will take an unacceptable long time ( which occasionally still happens in low light situation where ‘focus hunting’ happens). All DFD provide is the direction & how much
  3. I’m not believing on what I hear or read but based on logical analysis of algorithm control & functions. It is plain elementary physics and math.
  4. I’m do not think it is caused by DFD as the function of DFD is for the camera processor to compare the subject focus via contrast against data base images for focusing mechanism to decide which direction to move and by how much (alternative to Phase Detect function in other non Panasonic AF system). The flickering & bluring seem to take place on the fine focusing phase. It definitely has to do with the algorithm that dictates the resolution changes in the EVF for some logic related to processing power allocation.
  5. When intelligent AF is chosen, you allow the camera to decide on AFS or AFC. If you work do not require you to do continuous focusing on multiple frames shooting over moving subject, it would be more stable to select AFS. I’m not bothered by what I see in the EVF when trying to capture moving subjects, there are more challenges to occupy my priorities on getting a good shot over the short spans of time. It only matters to me on getting the AFC to work determined by final results.

  7. Selecting the APSC mode on the SL2 extends the 90-280mm to 420mm without reducing any f stop with 20MPx still available with autofocus. Try shooting BIF with a manual focus lens, I would only say ‘challenging’.
  8. The VE90-280mm + SL2 works fine for me on BIF. On APSC format, the range extends to 420mm without lost of aperture like a teleconverter would and I still get a decent 20MPx. Beyond that, choose the birding spot intelligently that the reach of the lens works just as locating the appropriate spot and time to get the sun at the right place. I also found novice photographer two common trendy habits. One is to start shooting whenever the subjects appear regardless of distance and direction against the sun. The other is the trigger free habit on high drive speed. In other words, highly quantit

  10. Indoors studio shoot, the VE 24-90 can be used to good results. However for outdoor shoot on achieving shallow dof to separate subject against background, both SL75 & M 50 Noctilux more than does the job. In addition to background bokeh, combined with OCF to create additional subject to background separation through deliberate background underexposure to bring viewer attention to subject (fine art portrait artist have been using this trick for hundreds of years). The SL75cron allow the use of AF on the L mount cameras for fast shooting and ease of use. To achieve more backgr
  11. Butterflies do not hover on same spot like bees do. In my case, it was pure luck.

  13. Did you mean you found it hard to lock focus or find difficulty in keeping the focus tracking on the subject frame after frame?
  14. I've mentioned it in my post of the image earlier in the SL2 Images tread that I would have preferred to use MF with a reduced apeture from F4 to F5.6 using prefocus on the branch. However I was tracking the birds while they were flying in on AFC / tracking and I did not have the time to switch over to MF as it was just a short stay before both bee eaters took off. Yeap. For fast moving subject towards the camera with a bird no longer than 20cm, the SL2 on AFC/tracking had no problem nailing sharp focus on the Stork Billed Kingfisher coming my direction at my eye level as below. Stor
  15. Your comments about the SL2 is fair. There is no perfect camera to start with and end with. My story with sticking only to Leica FF cameras (SL2 & M10R) is only because of the IQ produced by Leica glasses. Leica does not have the glass & body to support sports & wildlife. Even if Leica produces beyond the 280mm focal length range, I doubt I'll be interested to own such a lens as it would be bulky & costly, making international travel tedious. My SL2 is my all rounder workhorse from landscape to wildlife and I almost only mount SL lenses on my SL2 except using M50Nocti
