S 006 focus error

EVF cameras will at some point surely be the major product - it is cheaper to produce and maintain and at some point will mature and loose most of it's current down falls no doubt.

For high end SLR cameras (such as the Leica S or pro grade Canon/Nikon cameras) there is absolutely no contest today about the superiority of OVF. EVF simply are too slow, too low in resolution, too eye tiring, too finicky in their implementation on todays cameras that I refuse to use them.

 

Sure it is a bad example, but when I recently (unwillingly) upgraded my MM to the newer model, I also bought out of curiosity a EVF to go with it, just to see how that old tech worked - well it exactly (very precisely really) enforced all my doubts and critics about the EVF technology. Granted the Leica EVF for the M10 generation bodies is ancient tech by now but that is the prime example about everything that is wrong with EVF.

 

Regarding the ability to focus fast lenses: I do use custom made Canon OEM full matte bright screens in my Nikon bodies (no split screen and very sensitive for fast lenses) these work fantastic and truly precise for fast lenses as my Noct Nikkor or lenses like a 105/1.8 AiS - no argument there that an OTUS could not be focussed precisely as of a lack of available tech with OVF.

I had to precisely shim these focus screens on the D800E though (shims are supplied in the kit), to get the perfect precision.

 

Now there are no faster lenses then f2 lenses for the S system (and highly unlikely ever will) the available manual focus screen in the Leica S is by itself perfectly capable of precisely focussing manual focus fast medium format lenses - in the current S it is just a lack of body design that doesn't allow of the user to finely calibrate that focus screen to what really happens at the sensor (with the same resolution Nikon D800E the focus screen mechanism is engineered to be shimmed by design).

 

The last point about this though is a very important one (if one is honest, even a point that speaks against EVF in terms of focussing precision):

With 35mm or medium format systems, the most critical factor in determining perfect focus with very fast lenses is not wether EVF or OVF technology is more capable of displaying focus errors precisely enough.

It is in fact the photographers themselves who are the cause of missed focus.

 

When shooting a portrait with a 58/1.2 Noct-Nikkor on a D800E or doing the same with a Leica S and 80/2 Planar or using a 100/2 Summicron, the impact of just slightly swaying your upper body back or forward, or the sitter breathing and ever so slightly (a few millimeters really) moving their face has such a much bigger impact on technically accurate focus then a tiny misalignment in a focussing screen.

Now the OVF has a slight advantage - the photographer can see truly life, when this occurs and can time the shot on good camera bodies with almost no delay.

EVF cameras of today do have a longer delay between what you see and what really happens. That deal can be critical.

 

I admit, that the Leica M accessory EVF has atrociously bad delay from when one presses the shutter release until when the camera finally will have decided to maybe inform the shutter to please release if convenient.

Also the Leica S2 isn't the best example as of it's rather very long delay between pressing the shutter release and actual exposure (you can really nicely compare this by shooting an old S2 a digital M, a modern Nikon DSLR and then a camera like a Nikon F3 or a Leica M6 and those old film cameras will truly shine - true life view, no delay whatsoever).

 

OVF all the way! You see a pattern here ? ;-)

 

The pattern is clear. hehehe

 

Oh well, at the moment, all these OVF is inadequate, hence all these new tech of overlaying electrical information data on OVF to make use of best of both world. Be interested to see what Canon is going to do with their new patent technology for electrical ovf in their future camera.

Now that would be of course beautiful - retain the advantages of an excellent OVF like the one from the Leica S (really, who was not positively surprised when looking the first time through a Leica S camera ?), and add useful features from an electronic overlay - even allowing for a live view projection into the finder in an optional mode (it should not always be on, as live view mandates an open shutter  to work, adding shutter lag to the exposure as the shutter has to close first again).

I could really see the use of this technology in a Leica S.

I think the best situation is that the new S will be a mirror-less camera, no mirror slap, electronic shutter incorporated, so it's truly silent mode, the size of an SL, with a 4mp viewfinder EVF (I know you will disagree) that has 1.0x magnification, and at least 300 over focus point that cover at least 75% of the sensor ala A7r2 that will allow you to even do eye focus accurately....

 

Wishful thinking I know...

With or without mirror: OVF is important for me. The best solution for current S bodys is adjustment: finally I can report that after the second travel of my S kit to Leica Germany focus seems to be perfect.

 

Summarize: after countless trips to Germany both my M240 and v1 Mono focus fine with my 21/28/35/50 lenses. For longer than 50mm work I switched to a 006 which finally also nails focus with my 70mm and 180mm.

 

In any case of further issues I will let you know...

Dirk, this technique/techno used by nikon D5 seems to be the answer to what we are all looking for!!!!

An automated inbody adjustment to sync the Phase detect module using the Contrast detect AF on sensor!!!! 007 should be able to do that!!!! of course, we are talking about leica, so, you know....

Yes Kim, I read about that newly introduced procedure of automated AF fine tuning on the D5.

 

It has it's shortcomings too as I hear (read on the Nikon D5 blog of Thom Hogan's site - he is quite the Nikon guy).

 

No worries, Leica will eventually introduce this tech in a few decades ;-)
