Focus peaking is nothing to do with electrical connections between lens and camera. I use it with legacy film lenses all the time. My A7R has it on all the time unless I switch it off it in the menu. I had to allocate a button on my EM-1.

Maybe I was too brief in what I wrote, so let me try again being a bit more thorough. I agree that the electrical connection should have nothing to do with it, but it does in that there is a difference in activating focus peaking when electrically turning on manual focus with an electrically connected lens versus all manual lenses (legacy glass or new all manual such as the Laowa). The Olympus EM1 MKII treats these cases differently.

With an autofocus m/43 lens, for example the Olympus 60mm macro, if I have focus peaking turned on in the menus the instant I go to manual focus focus, peaking turns on. Similarly, with all my other autofocus m4/3 lenses, I leave in on in the menus and it simply works by switching to MF. Having focus peaking on in the menus does not have the same result with all manual lenses such as the Laowa. With legacy glass it senses a lens is there, but you have to turn on focus peaking with a button. Trying to turn in on in the menus will not turn focus peaking on.

While I get your point in that the lens has nothing to do with where the data for focus peaking comes from, the fact is that legacy glass, or in this case a new all manual lens, requires a extra step. People looking at this lens who do not regularly use legacy glass might want to know that and how to access that feature. That is why I brought it up.

My last point was that it would be nice if there was a minimum electrical communication between the lens and the camera so it would record what the focal length and aperture is for meta data. Obviously one can correct that later on to some degree, but that is a nuisance. I was also wondering if there was electrical communication between the lens and camera we would not have to bother with having to separately dedicate a function button to turn on focus peaking. I.E. would it treat it like the case where MF is selected for an autofocus lens. Hope that helps to clarify.

Highly desirable indeed. Dream on!

As for turning on Focus Peaking, it is good to be able to turn it off in mid shot as it can be a nuisance, at least with macro lenses.

I don't know which camera you have, but with the GX8, focus peaking switches on when I switch to MF, regardless which lens is mounted, also those without any electrical contacts, and as long as it's turned on in the menu.

One piece of information that the camera actually records with lenses that have no contacts is the focal length, or at least Panasonic cameras with IS do, since the camera will ask for the focal length once you mount such a lens or switch the camera on with such a lens mounted. That would be very helpful, and I it's something that should be suggested to Panasonic.

That only happens if you set the FL in the menu. I have my EM-1 on 105mm, which is over-ridden but any fully-wired lens.

On Panasonic cameras with IS, you don't have to set it in the menu. The camera will always ask about the focal length when switched on with a non-wired lens mounted.

I have the new lens. It's a great lens. I've shot star trails and landscapes also. My EM-1 MKII "s focus peaking works perfect and I love this lens

I got mine a couple of days ago and have been shooting various things with it to try it out. Even at f/2 the quality is quite good and by f/2.8 about the same as the Panasonic 7-14 to the corners. No decentering noticeable. It's easy to correct the barrel distortion and vignetting in LR when required, and focussing with magnification works well also. I've tried it on my EM-1 Mkii but have been using it mostly on the GM5, and carrying it with the 12-32 and 35-100 f/4-5.6's. What a tiny kit!. I haven't used the filters much yet but they seem to be of decent quality.

As I have a lot of other cameras and many, many lenses I'm quite used to manual use on these cameras.

What an impressive achievement at the price and size. My Panasonic 7-14 isn't going to come with me much anymore.

Reversed onto m4/3 gives very good macro FOV 3mm x 4mm, working distance about 12mm.

Any samples yet? : ) This makes a GM5 look incredibly appealing for me.
