Currently using my QX1 with the SELP1650. I was eyeing the Sigma 19mm F2.8, cheap and wide enough for my usage. Another one in my consideration is the Sony 10-18mm F4 OSS. This one covers full frame as well at 14mm to 18mm, so it can do double duty together with my A7R and A7S. Other lenses I would consider is Sony CZ 24mm F1.8 ZA. Sold this off with my previous NEX7, it's the best lens period for the APS-C E mount.

So as per current, I got my needs covered, SELP1650, 24-70mm F4, 55mm F1.8, and 35mm F1.4 Summilux M mount with adapter. The lens other than that SELP1650 comes from the A7R I was using before I got my QX1.

IMO, don't bother with sports, the refresh rate and pan and zoom between the QX1 and the phone isnt fast enough to capture adequate sports photos. As for wide angle lenses, that SEL16F28 is dicey, lots of users reports saying the lens isn't uniformly sharp across. It sure is nice to have something that small with the QX1, but I'd go for the Sigma 19mm F2.8 or Sony's 10-18mm F4 OSS, even though they're larger. No comment on the zoom, I don't do a lot of zoomwork, plus they're slow for my taste.

For what I'm using for, it's great. For anything more serious, I'll take my A7S.

Video is secondary to me. Still shots first.

To me, the low light capability opens up possibilities not previously available because of the lack of lighting available. With the GH4, sure it has the best looking internal 4K recording out there, but if it's only usable up to 3200 ISO (from what I read), you're restricted to situations where it's well-lit. With the A7S I don't have to worry about lighting (not as much as the GH4 anyway), and I can now explore photography which was once forbidden and not available to me before due to the low light condition.

To each his own, I guess. I like the freedom of shooting at any kinds of lighting, and I don't do studio shoots or in situation with controlled lighting. Your situation may well differ from mine.

Yup, just got my LCS-QXA. Gonna test and see if it fits the 24-70mm F4 FE or not.

Thank you to DarkEmotion88 for the GP-VPT1 grip recommendation. Just got mine, and with features available to it, very useful! I may even use it with my other Sony cameras.

All the buttons work.

eBay as well. All I get are blank stares while searching for this a while back at the Sony Stores locally. A tripod that looks like a pistol with buttons that zoom and snaps photos?

This was advertised as working with the QX1 in one of the commercial videos of QX1. In that video, a skater was seen lining up his shot by looking at the AZ1. Reason why I didn't get this for my setup is because it is just a screen to line up your shot and rudimentary photo /video button to snap/record your footage. No way to change the camera setting on this. Plus I already have the VPT1 pistol grip tht does the same minus the live view.
