Regarding the zoom position locking switch, it actually locks at any of marked positions on the lens barrel (150mm, 180mm, 200mm, 250mm, etc). I use mine for astrophotography, so being able to lock the lens at a desired focal length is extremely useful when the lens may spend several hours pointing straight up at the stars. Really a tremendous lens at its price point.

Thank you for taking the time to review this lens. As I am in the progress of buying this type of lens, it will make a difference in my choice!

If you have a canon two times extender, it will work or EF mount on a canon and double your distance you have to account for your lighting and also auto focus does not work when you add the two times extender

Alot of people who have reviewed this beautiful glass have all said that it's hand holdable... I disagree with them (and agree with you!) Holding this lens and trying to get a perfect shot without cranking up the shutter speed is extremely difficult. I do agree that it's comfortable in the hands but I think it should have been made to "push / pull" for quicker zoom.

Thank you. I bought it in Italy after seeing your review! All works really well on my Z6 II. Thanks again.

Loving the panning sound effect, Bob! XD

I have the Z7II and have been looking for a review like this. Thank you! I bought one and was anxious that it wouldn't work.

Love mine... I shoot at 600mm handheld and get some great bird images...

6:30 , The end section of the lens is actually designed for push and pull

I appreciate this 1st look . Love to know about using this for video.... Thanks for the wide product range as well

Great presentation , just purchased this lens and for the price it is superb 👍

The Sports version is a lot heavier, has full weather sealing and a 105mm filter thread as opposed to 95mm on the contemporary version

I'm relieved after seeing this video because I just ordered this lens, but then I was worried it wouldn't work with the FTZ mount and my Z6. I assume it worked fine with your Z6?

Great review Bob!

we did a shoot with Moe Notanis !

Nice panting sound great review

Nicely done but several instances of incorrect/incomplete info. Maybe research first, video later? Good presentation except for the factual lapses.

Good vid

Lens is slow and fuzzy

Thanks for an interesting first look at this lens. Your video would be more enjoyable without the swear words.
