So the adapter works positively with the sl? Theres no play in the mount?  I had issues with the leica m macro adapter to L mount before so im wary to use kipon again, but i always wanted to try g lenses.

I decided to go down this rabbit hole and have been very pleased so far with lens performance. 

Here are my findings...

Kipon adapter is built well and has no play.

45mm & 90mm work flawlessly. Incredibly Sharp. 

35mm exhibits corner smearing wide open and goes away around 5.6 / 8. Worst performing lens on digital sensors. Needs a PCX Filter.

28mm needs the tabs chopped off and works beautifully with the SL, no corner smearing or drastic color shifts compared to sony A7R. No need for a PCX Filter imo. Amazing lens.

Considering buying the legendary 21mm and chopping off the tabs as well. Another user has mentioned corner smearing when converted to M-mount. Hopefully this is not the case. The rear element does not protrude as much as the 28mm. Anyone have more insight or a copy for sale?

Late to the post. I found that you actually don’t need to remove the tab to fit g21/28 on SL body. The tabs will protrude into the rectangular opening in the body limiting the rotation of the lens-adapter assembly. The trick is to install the adapter on the camera first. G lenses actually don’t rotate when installed on the mount. I am only curious now if the rear group including the round tabs of  g35-70 fit into 36x24cm opening.

Can anyone comment on what the focusing experiencs is like with the Kipon adapter? I have some legacy Contax/Yashica lenses that I love and am adapting, but I'm drawn to the G adapter because of the much shorter flange focal distance of the G cameras, allowing the lens to sit much closer to the body.  I think this will be especially beneficial on the CL.  But I've some got some reservations anout manually-focusing an AF lens via an adapter.  Thanks.

You've gotta focus with the metal ring on the kipon adapter. It's stiff, and thin, so if you've got quite large/thick fingers it could be a pain. 

Takes a while to get used to it, but well worth it for the amazing lenses you get at this price/quality ratio. 

Remember the 21mm has quite prominent magenta vignetting and the 28mm ever so slightly (but still better than the sonys).
My favorite lenses on the SL are 28, 45, 90 !

I actually went ahead and ordered the adapter and just got it yesterday - great timing!

The focus rings is not the greatest feel, but I'm getting used to it.  It seemed to have a rough spot where it stick a little, but it feels like it's breaking in.  Not as nice feeling as a true manual focus lens, but it works.  I have the 28, 45, and 90 G lenses and feel like that's a pretty ideal spread and a relatively compact set.  I wish I could use them on my CL (which I prefer in many ways over the SL), but the crop factor of course turns the lenses into weird effective focal lengths, and I don't think the 28 is even useable without trimming, which I'm reluctant to do.

Did you also find you can adapt the 28 G to the SL camera without clipping the rear tabs on the 28 G? I am able to adapt the 28 G to Sony Emount with a flange distance of 18mm without any need to clip the tabs on the lens. I think the Lmount is a flange distance of 20mm.

The 28 fits on the SL but not as readily as the 45 or 90.  You have to give it just a little bit of extra push to engage the bayonet mount, which is a little nerve-wracking, but it seems to work okay once mounted.  I cannot get it to mount on the CL at all.  I think in both cases it would be easier if the tabs were trimmed, but I'm not 100% sure that the rea relement would clear the CL's sensor.
