I would be happy if I could just program it to a button so I didn't have to dive into the menu to switch it.

I checked awhile ago to see if it could be programmed. That would be nice, but "auto" would be even nicer for those of us who forget the occasional extra step like this!

The negative optical effects of enabling the Electronic Front Curtain Shutter (EFCS) at high shutter speeds has previously been discussed on here to some length, especially with fast lenses with a maximum aperture of f/1.4 or more. However, I was curious to what extent the "harsh" bokeh of the Loxia 2/35 could be improved by disabling EFCS.

All images were taken with a tripod-mounted A7rII, where shutter speed and ISO were balanced to give even exposure. The lens was focused at minimum focusing distance with out-of-focus areas containing specular highlights and foliage.

EFCS does have an impact on f/2 lenses but it's much less noticeable than when compared to faster ones.
A more noticeably impact can be seeing when stopping the Loxia 35/2's aperture down to f/2.5.

Shot in silent shutter (Same effect as EFCS turned OFF)
Starting at f/2.5, rendering is much smoother and focused area has already high contrast.

OOF rendering difference between f/2 and f/2.5 for the Loxia 35

I've Loxia 21, 35 and 50 and love it, I primarily use these for landscape and love the depth and sharpness.

p.3 #4 · p.3 #4 · Loxia 35 revisited

just got one some weeks ago. i am very surprised with this lens.

how do you shoot it in general to maximize colors and contrast? i got the impression this peaks quite open like maybe 2.8? in spite of resolution deficit, rendering is very very interesting not wide open, but close to it

any advice?

Local Church. Spring. Slightly imperfect focus stacking if you look closely.

But it does show the nice bokeh even at f8 when you are up close, and good close focus performance.

A good copy is optimal at about f6.3; stopping down further may give you better corners on some copies at the expense of slight diffraction dulling.

But really choose you settings for your photographic intent rather than optimising! If you need f2.5 your intended DOF or bokeh look, who cares if resolution is better stopped down? If you need f8 for depth, who cares if micro contrast is a touch better at f5?

But for landscape where there are non infinity and infinity components, focus stacking of f6.3 frames in my approach.

I came from both 35mm Zeiss Biogons for film. I actually preferred the f/2.8 'c' version, which was small and quite good micro-contrast. I purchased the Loxia the minute it was available. The film Biogons never performed on the Sonys. The Loxia was better in every way, so I guess it is a matter of perspective., but it definitely isn't a modern lens. The F/1.4 ZM is probably a technically better lens, especially at wider apertures, but the Loxia gets more use.

Do the corners ever get sharp on the Loxia Biogon 35/2? They never did on a digital Leica with the copy of the Biogon ZM 32/2 that I purchased in the hope that it might save me from having to get both the C Biogon ZM 35/2.8 and the Distagon ZM 35/1.4. I should have realised that the Biogon 35/2 would have to have been incredibly great to replace two lenses, each of which is stellar in its own way. I returned the 35/2, shelled out for the C Biogon and the Distagon, and have never been even vaguely tempted by any of Leica’s 35mm offerings.

Hi,

thanks for the answer. I do not care much at this stage about resolution. certainly the aperture should be take regarding the artistic value of the photograph and not optimization. That is why i am asking about color/contrast because if you want to go in the direction of "graphims" maybe in bw, then this is significant

c biogon looks extremely atractive. are you shooting leica? how does it perform in the sony camera?

Optimal at 6.3 meant optimal - not just optimal resolution; so best colour and contrast as well.
But of course getting the right DOF or bokeh look will matter,more than colour and contrast.

The C Biogon ZM 28/2.8 is superb on a Leica M camera and terrible on a stock Sony full-frame body. It probably performs well on a Kolari-modified thin stack Sony body though I have no experience with this. Another solution is to use a PCX filter as described in this link
https://phillipreeve.net/blog/rangefinder-wide-angle-lenses-on-a7-cameras-problems-and-solutions/#Zeiss_ZM_28mm_28_Biogon
but achieving infinity focus requires a shorter than standard adapter and/or the removal of shims.
