Great series Lester.

Thanks Peter.

Your shots are amazing, specially like the kingfisher.

Thanks for the 'well come'

This doesn't sound normal at all. I have an early lens which was paired with a 7D and even before the FW adjustment it never did anything like that. I don't recall seeing that issue mentioned either.

The typical freeze was easily overcome by manually adjusting focus so the lens had something to grab onto. Mainly it happened at the longer end while going from one extreme of focal distance to the other.

The only time I had something like you're describing happen was when I'd set the focus limiting switch on. That required a personal software reboot lol.

No experiences but some thoughts...

It's very easy to introduce vibrations with this lens, perhaps the real world excitement? wind? ground vibrations? Something you're much more likely to notice in rcontrolled situations.

Nonetheless, VC seems to be a double edged sword on this beast.

Good morning all.
I have a problem with my 3 week old Tammy and was wondering if anyone had a similar experience.
While out shooting BIF yesterday I lost AF and had to reboot the camera so to speak then AF worked fine.
Is this something I'm going to have to live with or should it be sent back?
Any help is appreciated
Thanks
Tim

I had a very similar occurrence with this lens the first day out with it. Immediately attached a different lens to the camera, and it worked fine. Re-attached the Tamron and it still didn't work. Went back to the car, removed and replaced the Tamron on the camera, and it worked fine. I have not had this happen since. Clearly it must have been something with attaching it to the camera, but it has never happened before or with any other lens. Thankfully it hasn't happened since, and I have no idea what caused it then.

The firmware update was only at the start of production, probably a year ago. Unless this was a secondhand lens or old stock it should already have the update.

Has this happened more than once.?

Thanks Lester it's the first time it happened and not old stock as it was ordered from B&H almost 3 weeks ago and they assured me it was the latest as all old stock was returned. I'll try cleaning the contacts if it happens again.
Thank you.

Interesting I'll have to monitor it closely if it happens again and YES I may have had the limiter on 15m to infinity so I wouldnt miss focus on the BIF's and I think thats where I made my mistake

Thanks everyone for the help and now I have something to chew on and as said maybe I need a reboot lol . Still in the learning phase with the Tammy as well.

Hi Guys,
After Looking at photo's and Reading of the first 100 post I was already in love with this lens And I started
Saving for it. On Sat I pick her up and when I got back home went out for a test run The Weather was pretty bad very overcast and about
to rain (which did 45min later) Here are 2 photo's that I took, I'm pretty happy with them Sp since the light pretty bad and I was shooting
handheld too Enjoy.

That sure is the beauty of 500+mm

Nice capture - my little city get GBH but have never seen a nest... to capture one (find one!) is on my bucket list

TBH I never use the limiter switch on this lens.

If your problem was due to the limiter then this is a feature of limiter switched lenses because it has been reported on other lens, including if I remember correctly, the 300 f4 IS which has a much more useful limiter range.
