Thc879 Posted May 4, 2018 Share #1 Posted May 4, 2018 Advertisement (gone after registration) Would support for automated focus stacking such as setting a near focus point and a far focus point and the number of exposures be something that Leica could add to the firmware of the SL or would that require design changes to the hardware? This would be a great feature if they could do it. 1 Quote Link to post Share on other sites More sharing options...
Advertisement Posted May 4, 2018 Posted May 4, 2018 Hi Thc879, Take a look here Focus Stacking. I'm sure you'll find what you were looking for!
mmradman Posted May 4, 2018 Share #2 Posted May 4, 2018 AF lenses have focusing element moved with stepper motor, this is device that allows fine linear motion, so all the hardware for focus stacking is already in place. What would be needed is {a] either change in Leica mind set or big market pressure, change in FW or [c] skip a & b and buy Nikon D850. 2 Quote Link to post Share on other sites More sharing options...
Irakly Shanidze Posted May 4, 2018 Share #3 Posted May 4, 2018 Leica's mindset traditionally has been focusing on the essentials. Focus stacking is a highly specialized feature indispensable in macro photography, but less then necessary elsewhere. Besides, even in macro, for the best results, stacking requires photographer's attention. Quote Link to post Share on other sites More sharing options...

mmradman Posted May 4, 2018 Share #5 Posted May 4, 2018 (edited) why not simply use this ? http://www.heliconsoft.com/heliconsoft-articles/helicon-remote-making-focus-stacking-precise-and-foolproof-by-paul-harcourt-davies/ To get stacked image you need, as a minimum, to produce multiple images with slight focus increment. Link does not provide any advice on compatible cameras/lenses. Edited May 4, 2018 by mmradman Quote Link to post Share on other sites More sharing options...
rpittal Posted May 4, 2018 Share #6 Posted May 4, 2018 why not simply use this ? http://www.heliconsoft.com/heliconsoft-articles/helicon-remote-making-focus-stacking-precise-and-foolproof-by-paul-harcourt-davies/ this is only for macro use and only available for NikCan.... I use D850 for landscape focus stacking which is the main reason why I sometimes take that setup instead of SL on trips for landscape use; much easier and faster than manual focus stacking (which is obviously available). 1 Quote Link to post Share on other sites More sharing options...
frame-it Posted May 4, 2018 Share #7 Posted May 4, 2018 Advertisement (gone after registration) yep, no Leicas http://www.heliconsoft.com/supported-cameras/ so for the SL it would be a Rail+stepper setup i guess ?

Thc879 Posted May 4, 2018 Author Share #8 Posted May 4, 2018 I would really like this for landscape photography. There are times when going to f16 or less just isn’t enough or the best way to get the best image. On the other hand I am sure there is a fixed amount of nonvolatile memory in the SL to store the firmware and don’t know if there would be enough available to add a fairly complex feature like focus stacking.

amoebahydra Posted May 10, 2018 Share #9 Posted May 10, 2018 I use Cognisys Stackshot for the purpose; however, camera control cable for Leica are not available and have to modify a Leica remote release cable in using the Stackshot.

Thc879 Posted May 10, 2018 Author Share #10 Posted May 10, 2018 I don’t know if Leica reads these posts or not, but it would be great if they would at least consider adding some support for focus stacking to the SL firmware. Quote Link to post Share on other sites More sharing options...

Lets hope they do. Maybe excuse would be that no dedicated L mount full frame AF macro lens exist yet. 1 Quote Link to post Share on other sites More sharing options...
Thc879 Posted May 10, 2018 Author Share #12 Posted May 10, 2018 Probably so, but I would like to use it for landscape photography using the 24-90mm or the 16-35mm (on order). Quote Link to post Share on other sites More sharing options...

What would be needed is {a] either change in Leica mind set or big market pressure, change in FW or [c] skip a & b and buy Nikon D850. It would be nice if Leica opened up the API for App development. This seems like a straightforward feature to implement in an iOS/Android app. Quote Link to post Share on other sites More sharing options...

Panasonic has post-focus and focus stacking using 4K. Leica does have access to the technology. Quote Link to post Share on other sites More sharing options...
HeinzX Posted May 12, 2018 Share #15 Posted May 12, 2018 (edited) I use a Cognisys system for focus stacking and the Helicon software afterwards. All these things were bought for a Canon camera together with Canon Macro lenses. And the workflow was very comfortable with all these things together. In case of need I can use all of them with my SL - the macro lenses are adapted with a novoflex adapter. But unfortunately there is one restriction. In contrary to Canon, Nikon and other systems there exists no cable for automatic releasing the shutter for the SL. Cognisys has told me, that because of technical reasons they are not able to deliver one. Therefore I have to release the shutter for each step - which ist possible - for every camera - including the Ms - but less comfortable. P.S. It is a shame, that Leica has no own native Macro lens for the SL - not even in the road map - at least according to my knowledge.

Then you can get all those lovely S lenses cheap since you have the adapter. It's a great setup. I also use the 100 APO-R in a pinch, such as needing to use the APO Elpro for 1:1 reproduction.

graeme_clarke Posted April 17, 2020 Share #17 Posted April 17, 2020 Here are a couple of shots made using Helicon. SL (601) and 100mm R f2.8 macro. Camera mounted on an ISHOOT macro focusing rail 150. The lens was set at f2.8 (to through as much of the background out of focus as possible) and a magnification ratio of 1:2. For both I images found the far and near points for sharp focus using the magnification facility in the viewfinder, and noted the position using the mm scale on the rail. They were about 40mm apart. This article gives a step calculator http://extreme-macro.co.uk/focus-stacking/ For f.2.8 it suggests a step of 0.091mm. As one rotation of the screw moves the whole camera and lens 1mm the closest I can get by hand is about 0.15mm interval by making 8 steps per revolution with an exposure each. Starting at one end using a remote control I made 352 exposures for the first image and 314 for the second. Stacked using Helicon Focus 7 then minor post processing adjustments in Lightroom and Photoshop to tone down some highlights and improve texture. The exposures were made in the evening when the wind had died and the flowers were still - any slight twitching in the wind leads to ghost edges in the stack. It is somewhat tedious and care and consistency are needed. What is crucial is the image must not move, which makes outdoor shots very difficult to accomplish. I've still got a lot of learning to do!!! Take care and stay well everyone, Graeme Welcome, dear visitor!

Pelu2010 Posted August 15, 2021 Share #18 Posted August 15, 2021 Hey, i just found out that the Leica sl2s has follow focus for video. to me it does not make any sense that the video mode can do this and the photo mode can’t. i Hope they introduce this feature. And by the way this does not clutter up the menu system. the other suggestion would be: make an advanced menu for people that need features that need them or think they need them. We can call it „pro“ oder „adv“menu. this menu would also be nice in the „photos“ app. For me as Timelapse photographer it’s limiting not be be able to bramp my timelapses. Yes I know Incan do this with other cameras and other software, but I want to do it with these lenses and this sensor. what do you think?

Bob Hartung Posted August 22, 2021 Share #19 Posted August 22, 2021 (edited) This is not only for macro work. It can become invaluable for landscape to have the near, mid, and distance zones all tack sharp. Coupled with sensor shifting this would kill the need for the Hasselblad X1d or the Fujifilm 100 Mpix bodies. Just may $0.02 The lack of this feature is the only thing preventing me from purchasing the SL2 now.

jaapv Posted August 22, 2021 Share #20 Posted August 22, 2021 What feature? Focus stacking is a photographic technique that can be applied with any digital camera. Obviously post-focus can make it easier, but the big drawback is that it is JPEG only. 1 Quote Link to post Share on other sites More sharing options...
