All my lenses (Nikon F2.8 FX Pro Gold band lenses ) and on either D7000, D7200, D750 & D810....and they still have slop...but then I was at one time used to dealing with ± .001 & ±.0001 tolerances...so to me anything loose is slop.

with that size of lens, and if it is noticeably moving while attached to the camera body, it will eventually bend or break at the contacts.
If the lens is supported properly, it will not bend or break at the contact point.

I agree! When you get to lenses of that size you mount the camera to the well supported lens not the other way around!

I have and use that Sigma 150-600S lens on Canon bodies with no issues at all.
How tight is your boy on other (lighter) lenses?
I strongly recommend NEVER handling any heavy lens like the one in question by holding only the body. The tripod mount is there because cameras and camera mounts are just not strong enough for heavy long lenses with long lever arms to boot..

That is not uncommon, nor is it limited to third party lenses, and unless there's a lot of play it won't effect images and cannot possibly damage your camera or lens unless the locking mechanism is bad and comes unlatched.
If it bothers you, send the lens in to Sigma (assuming it's under warranty) to have it fixed. They should be able to shim the bayonet mount to reduce the play to a minimum. However, once that's done the lens focus will likely need to be re-calibrated (which, because it's a modern Sigma lens you might be able to do with the USB dock... but I'd expect Sigma to do it anyway, since they are working on the lens).

I've been thinking about that lens for use on my Nikon D810. My other option is the Nikon 200-500 F5.6. The Sigma is more expensive so it isn't a question of saving money. It gets very good reviews.
I have been using the Nikon 200-500 MM about 6 days a week for the past 5 months. I have since put away my Nikon 300 2.8 and my 200-400 f4 cause the new 200-500 is that sharp (and more importantly is way lighter to carry around cause I don't use a tripod or mono pod cause they get in my way). I reverse the tripod collar and use it an a carrying handle. I use GROUP AUTO FOCUS on the center spot, continuous shooting. My keep rate is about 97% on sharpness. Trust me, you will not be disappointed in this lens. I have been using F6.3 and it seems to be my sweet spot. I photograph a LOT of moving birds and the lens tracks beautifully. Well, I guess I track them but the lens does what I expect it to, it DELIVERS.

It is completely NORMAL. Most bodies and lens combinations are built that way. It's just more noticeable with lather lenses.

Yea, the lens is built like a brick out house excuse my wording. I like it's quality build. Maybe on the heavy side but that's to be expected with the sturdier build. The pictures are better than I expected. But sometimes I notice a variation in light quality of a picture with the same settings in use. I associate it may be from loss of contact of the lens and camera contacts. Unless someone can change my mind. Does anyone understand this may be happening? Where the contacts are not contacting solid or are crossing each other when the lens moves on the camera. Could this be possible?

Someone suggested I contact Sigma support to get their take. I want to keep the lens or get a replacement. thanks for your input. Your verification of having no problem with slop makes me feel better.

I contacted Sigma while back concerning the slight amount of rotational play, and they said it is normal, and more noticeable with larger lenses. I have it in mine and the lens performs excellently.

Lou, Can you quantify the movement? 1/4 of an inch?1/2 Inch, 1/8? or just a very slight movement?

Yes, I've noticed same thing with my Nikkor 28-300mm with prior Nikon D610 and now also with 610 replacement, Nikon D750. It never adversely affected quality or anything else. I do "not" notice this with my D750 and other lenses such as Tamron 150-600mm, Sigma 15mm fisheye, and Nikkor 60mm macro. From what most other hogs are saying, it appears you and I have nothing to worry about. I love this forum so we can ask and share this type of info.
