I ordered a 100-400L on Black Friday (used from LensAuthority) and it just arrived today. I can't wait to get out and shoot with it. Unfortunately the weather isn't going to cooperate this week where I'm at (up in Minnesota).

Quick question about the lens:
Is it normal for the zoom-tightening ring to turn the manual focus ring as well?

It doesn't seem like a problem and as I examined the lens it looks like this is inevitable based on the design. I just wanted to check, since I have a 3-day inspection period. Since I got it from LensAuthority, I trust that it was well examined before being sold. Everything else seems to be in good working order.

Thanks for the feedback.

I dont have that Lens but I think that it has a Push and Pull zoom not a Turn Ring .

When I had that lens mine did that. To tighten it i just held the mf ring in place so it didn't twist.

I don't have one either but David is correct. There is no ring to turn for the focal length adjustment (zoom).

Since you guys didn't own the lens you are misunderstanding. There is a "zoom tightening ring" to lock the lens in place at any focal length.

Thanks for that. I usually learn something new every day.

Yes, it is normal. Hold the focus ring when adjusting the tension ring; I do it with a kind of "pinching" motion. Cradle the lens in your left hand, with your thumb on the tension ring and middle finger on the focus ring; then roll your thumb down to loosen or up to tighten, while using your middle finger to keep the focus ring stationary.

That's what I've been doing. Thanks for the feedback. It looks like it's normal. Once the tightening ring is loose enough I don't have that problem, it's just when it's on the extreme ends of tightening or loosening.

Normal. I hold the focus ring while adjusting the zoom-tightness-thingy.

950. The glass is pristine. There are a few nicks on the body and there's a small piece missing where the lens hood attaches, but it took me a while to even find it. It doesn't affect the hood's attachment or anything. All in all, I'm pretty pleased. I was a little hesitant at first since it was previously a rental, but the people at LensRentals/LensAuthor​ity really seem to test their gear and make sure everything is good to go. Plus it came with a 90-day warranty.
