Fuji in-camera focus stacking

[Will]

Anyone on here using a Fuji with in-camera stacking for macro?

Nice shot. How does the camera alter focus with that lens?

[bobfriedman]

there are several ways without stepping through the focus plane in-camera, the easiest is to use a focusing rail such as the stackshot rail and controller. I used a Combo Ultima XL35 with a stepper motor on the rear standard to adjust focus.

Wili, I interpreted your question to be about in-camera focus stacking, as in Olympus, Panasonic, and some Nikon cameras, that change the lens focus automatically and take pictures at each focus step. I think Bob's solution, while beautiful, does not produce equivalent results, because the perspective changes with each step.

There are manual methods for doing true focus bracketing even with manual lenses. These involve geared cine "follow-focus" attachments like this:

I have used this method successfully for low-m stacking. But an automatic camera-controlled solution like that of my Olympus camera is a million times better. I know nothing about the Fuji system so can't help you there.

I notice that Bob says "with a stepper motor on the rear standard to adjust focus." [emphasis added]

Focus stepping by rear standard does not change perspective with each step. The perspective remains perfectly fixed while the camera sensor moves through the light field behind the lens. This is the ideal solution for low-mag stacking. It is the column labeled "Bellows Rear" at https://zerenesystems.com/cms/stacker/d ... versusrail .

Yep, I missed the "rear standard" part! Must be getting old (-er).

I am still not sure it is the ideal solution. Complex lenses with floating elements could give better results by actually refocusing the lens at each step.

Yes I mean in-camera Focus stacking with Fuji lenses. I’m not interested in stepper motor setups etc at the moment.

Sure, that's always a possibility. I was using "ideal" only in the sense of absolutely no change in perspective. That's the way it's used in the table at the link I provided. Bellows Rear is the only such focusing method listed in that table. The table does not exhaust all possibilities, of course. I expect that physics allows a lens with no focus breathing (no change in angle of view with focus), no change in perspective (no movement of the entrance pupil), no change in exposure (fixed effective f-number), and no significant aberrations (diffraction limited). The best lenses designed for videography may come close to that standard.

Wow, I love that photo up there. Vibrant colours, impeccably stacked.

another example with the 50R, with the stepper motor on the rear standard

Very beautiful.

Lovely images, good discussion, but, um, pretty far from what the OP originally asked:

[bobfriedman]

quite right.. I have to admit that I missed the "in-camera" piece.. my apologies to the original poster

[Lou Jost]

Nevertheless it was very nice to see your photos.
