bags27 Posted August 12, 2018 Share #1 Posted August 12, 2018 Advertisement (gone after registration) From what I can tell, peak focusing remains fixed on a single plane even if you then change the aperture from f1.7 to f16. Ideally peak focusing should indicate the expanding or shrinking plane of focus. Unless I somehow have this wrong, that’s what I would wish for in an upgrade.

Advertisement Posted August 12, 2018 Posted August 12, 2018 Hi bags27, Take a look here Peak focusing and depth of field. I'm sure you'll find what you were looking for!
Leica Guy Posted August 12, 2018 Share #2 Posted August 12, 2018 I think you’re right. I don’t remember it changibg with aperture. It would be a nice feature. 1 Link to post Share on other sites More sharing options...
stuny Posted August 13, 2018 Share #3 Posted August 13, 2018 Perhaps not since peak will indicate the plane of best focus. Instead, include (menu option?) an indicator or depth of field along with the peak. 1 Link to post Share on other sites More sharing options...
jaapv Posted August 13, 2018 Share #4 Posted August 13, 2018 Actually peaking indicates the areas with the strongest steps in contrast. It will become more prominent with smaller apertures, making it necessary to find the "middle" of the peaking zone. 1 Link to post Share on other sites More sharing options...

Ideally peak focusing should indicate the expanding or shrinking plane of focus. Unless I somehow have this wrong, that’s what I would wish for in an upgrade. A plane can never expand or shrink There is only one plane of focus and it (ideally) remains in the same spot independent of aperture. You mean DOF, which is not a defined plane but a gradual transition from acceptable sharpness to unacceptable out of focus. 3 Link to post Share on other sites More sharing options...
01af Posted August 13, 2018 Share #6 Posted August 13, 2018 From what I can tell, peak focusing remains fixed on a single plane even if you then change the aperture from f/1.7 to f/16. Obviously the lens doesn't stop down as you select smaller apertures until you actually fire the shutter—similar to an SLR lens. So in order to see the effect on depth-of-field, you must explicitly close the aperture ... does the camera have a DOF preview button? 2 Link to post Share on other sites More sharing options...
jaapv Posted August 13, 2018 Share #7 Posted August 13, 2018 Advertisement (gone after registration) That is correct, Olaf. I didn't notice I was in the Q forum and thinking manual lenses Link to post Share on other sites More sharing options...
beez Posted August 13, 2018 Share #8 Posted August 13, 2018 (edited) does the camera have a DOF preview button? Yes, a half-press of the shutter release stops down the lens to the chosen aperture, and shows DOF in the viewfinder.
