So, a lot of these uses discussed should be tripod mounted.

K5 on have beautifully soft & well dampened shutters.

I've never had a mirror slap or shutter reverb problem since the KX.

I use microscope lenses on a K3 and have all the time blurred pictures due to vibrations. Remedy are exposures over 5 seconds or using shorttime flash light.

PLEASE Pentax make us EFC available.
 
... maybe to be fixed by a firmware upgrade? If it´s availiable in pixelsshift mode, why not as an option for "normal" live-view mode? What do you think, is it possible to do?
 
OK obviously a special need Lotham. It never has been a problem for my macros etc.

No Mike this just gets the mirror up the mechanical shutter still fires.
 
That's what they are suggesting, not sure if it can be done.

Does make sense for LV etc to just use an ECS, seems the 810 does it.

Yes we are talking extremes here but an interesting discussion though.
 
A proper EFC shutter requires a programmable line reset timing behaviour to emulate the effect of a mechanical shutter curtain. Without, you are limited to slow read-out speeds risking the famous jello-effect and alike. Obviously not an issue with pixel shift but otherwise, it would be.

So, you need sensor support. The D810 has it, the D800E does not have it.

From everything I read, the K-1 and D800E sensors are identical or almost so. Which explains the affordability, but also slow read-out, and lack of ISO 50, lack of 4k and lack of EFC shutter.

Still, like the D800E, the K-1 is an excellent camera.

One of the great advantages of an electronic shutter (IMO) is that it's possible to get really fast flash sync. For example, it's very useful for fill-flash on a bright sunny day when I don't want to be forced to use 1/180 or even 1/250 shutter.

could you use a 2 or 12 second timer?

`that makes no difference, it is the shake of the shutter not of the mirror. The high magnification with microscope lenses also magnify vibrations.

interesting...But how about Sony A7r? ...I thought that it has the same 36mp FF sensor than Nikon D800E, Sony A7r has EFCS, or whether Sony A7r actually has it? ...

Ari, you spread false information which is a bad thing.

The A7r has no EFC shutter.

Which would be compatible with the assumption that D800 and A7r share the same sensor although AFAIK this is no verified fact.
