Reddit mentions of Meike MK-X1EM Metal Bracket Hand Grip for Sony A9 A7MIII a7RIII a7RII a7II a7SII Camera

It sure is. It's a little less ridiculous if you get one of those grip extenders for the bottom of the camera. The LA-EA4 is pretty magical as far as letting you use so many old lenses.

I don't really see why people are so into that particular lens, though - it's not awful but I feel like there are better longish zoom options. The 28-135, I think, is pretty deserving of its reputation though, at least for those of us who can't shell out crazy amounts of cash for a modern zoom. Especially combined with good correction profiles it really holds its own.

If anyone is still not in love with the Ergo of their Sony A7III Im here to let you know the Meike grip extender / tripod mount is decent.

Here

Its aluminum with a plastic leather texture insert, so not high quality, but I think its a better option then the Sony one based solely off the fact that it has a built in Arca Swiss style mount and also has another screw hole for a mount if your tripod has a different style mount.

I also ordered a thumb up grip to try out, though I may return it if it makes the AF ON button hard to press.

The grip extender however on its own has completely changed how comfortable the camera is to handhold for me at least, I have fairly large hands.

It's as the others have mentioned, but I'd like to add that you can get a third-party one for half the price like this Meike. I bought one for my X-T10 and it's good quality. As a bonus, it's also a Arca-Swiss quick release plate if you have a compatible tripod. Only downside is that you'll have to keep the supplied allen wrench with you to take off the plate to change batteries.

I got the grip as well. Love it! I still shoot my Nikons still, but less and less now days. You are going to be very happy. I would also recommend the Meike Hand Grip it is very comfortable and has a built in Arca Swiss compatible plate built in.

I said one of many grip extenders. There are many options ranging from 15-60 dollars.

(was $50)

I use the L bracket grip extender. Two in one solution for landscape photographers. A Canon EOS-R will be much bigger when you add an L bracket, and the Canon EOS-R will have the not so hidden costs of having camera & video specs from 2014 at the retail price of $2,300, a bigger body that cannot be made smaller for smaller setups

When I do video work I prefer a much smaller and lighter camera for gimble work, same when I use my smaller MF Zeiss lenses or small 1.8 or f2 prime lenses when I want to travel light and small. When I use my huge 2.8 GM zoom lenses or huge 1.4 lenses, I use a battery grip or grip extender. Best of both worlds when you start off with a smaller camera.
