my experience not that super with it, it is essential for close focusing and helps with lenses that are very open, BUT the working is very temperamental, sometimes is ok, others is not. I had issues since day 1 and had it replaced, eventually same story. I am not implying that there is an issue with all of them, but worth giving it a try if you can in a shop as it is not cheap...

I've found it excellent for specific use cases: wide angle past what the frame lines can do, 135mm and up (some would say even 90mm and up), macro, waist-level or floor level shooting (pets, kids, navels....), and so forth...

I don't use it all that often but when I do I'm really glad it's there!

Visoflex is convenient for precise framing or shooting from an awkward position, but you need to take into account that when using it there is a very noticeable shutter lag: for example, I would not catch the correct step phase when shooting on the street using Visoflex, the lag will be about half a step at the normal speed of a calmly walking person.

Interesting indeed. I don't do street but i shoot my grandchildren with the Visoflex 2 and i've not noticed more shutter lag than with my other mirrorless cameras. Rather less so compared to my Sigma FPL. May i ask how you're setting auto review?

Precisely.  What's being described is not shutter lag.  EVFs don't operate in real time.  The image displayed is delayed due to the time required to process and display it.  A general problem with most, if not all, EVFs (this phenomenon is, I suspect, the origin of cell phones recording images up to the shutter release to overcome the display lag). Using the Viso In dynamic situations, one has to learn to anticipate a half beat ahead. 

This, BTW, is a key advantage of the M's dual finders. As I've noted many times each VF has strengths the other lacks.  One shouldn't think of the Viso as a replacement for the OVF, but rather a compliment to it.

As far as display lag is concerned i find the Visoflex 2's results more than good enough compared to my other mirrorless cameras, similar to the digital CL for instance but better than the Sigma FPL. It depends on the auto review setting the way i feel it but I did not meter the lags so i may be wrong.

Isn't it the same EVF as in the Q2, roughly?

I don't recall seeing the refresh rate for the Visoflex 2 but what is it for the Q2, is it 60 hz?

I don't recall being bothered by the refresh rate, but I'd reckon if there were issues it would depend upon subject matter.

Autoreview off.

It will be very easy for you to verify this. Ask your friend or grandchild to walk at normal walking speed. Press the shutter button at the widest amplitude of a person's step that you see in the Visoflex, and then watch the result. Do the same via OVF (!!turn off live view!!). Compare the result

Call it pseudo shutter lag if you like. It is important that this is noticeable enough (0.3-0.5 seconds) to ruin a photo that has dynamics. I’m not even talking about the dynamics of racing cars.

Therefore, Visoflex must be used with some caution, being aware of its limitations.

With Visoflex2 you generally get the same view as with the back screen when LiveView is set to on. It is then a question of your personal liking if this is fine for you in cases that you want control different settings (blown out sky or Perspective Control etc.). But the Visioflex offers you more: As you can turn it upwards you get a finder that is useful for perspectives near the ground or for Macros. I like such perspectives a lot. With the Q3 or the new SL you have the tilt screen which is very helpful. 

Once you have a Visoflex2 you need it 😊. My normal configuration is 28mm mith Visoflex mounted.

I have just ordered a used one as I found it at a good price in Italy. My 21 SEM is en route, so I thought the visoflex might be a good add-on to get the field of view right in more critical applications. Additionally I like the rotating function, which is nice, since the M has no tilt-screen. Thirdly as the M11 has no IBIS (the one thing I really miss and hope the M12 gets it) having the camera up to the eye, when I would need to use the screen otherwise, is more stable as more points of contact.
