It does look pretty good, even better than his previous post I would say.

Man I am getting itchy about getting this but I think I would have to sell my 70-200 f/4 and some other stuff to get it. Unless I can get a bonus from work.

Here's another of the Hamerkop (thanks for the ID, condyk) at 340mm and 1/400 @ f/9 with 100% crop.

ROFL

I am wary of close up zoom test shots. That is not the typical use of a megazoom like this lens. Tests of subjects 50ft or more away would be more realistic and this is usually where zoom lenses show how far off focus they are. When I take my lenses into nature or to the zoo, I am not shooting animals 10ft away (unless I have scaled the wall to get that close up of Fido the lion, in which case, I probably won't be back here to share any photos!). These closeup tests are good to show the IQ of the optics, but I am curious too as to how the lens is regarding front/back focusing.

Any chance you can set up your tripod and shoot something outside in the exact same controlled method?

Excellent, thank you. I am looking more at the detail of the blocks and grass around the box, then the text on the box. Looks pretty good. That flower to the left makes a great subject too.

Plus, now I have a craving for chips, thanks a whole bunch!

I have to say that im very happy with this lens and thanks to those asking for stopped down shots as it is something i rearlly do with my big primes Yet it shows how well the SIGGY can work by just going to F8 im use to high IQ lenses and although its not up to some of my primes it is more than exseptable for such a nice range of zoom .
Looking at some other results it hard to say if its the user or the lens after all in one of my shots it made the lens look not so good ( my fault ) but then when i did the shot again re Lightrules advice the lens showed just how good it is.
iv not had a lot of chance at BIF shots or Jets so still more test's to do, i have done a few BIF and they are promising that i can say
To me a Limit switch would have been great and worth £150 more as i will miss that feature But good use of pree focus will help in this respect.
This lens is going to be hard to beat for range and price i hope other's are as pleased as i am - with there's.
No more testing from me on static shots it does the job well

Got my first shot of BIF today with this lens. I am not too good this and hopefully with a bit of practice, will improve.

The shot looks great on your site but the linked version here degrades it a bit. Not bad for someone that is "not too good at this".

Yeah no kidding... I would love to be able to track properly and get a shot like that. Unfortunately the type of birds I have available are blackbirds, cardinals, and blue jays, and those stupid things are too fast for my poor panning skills.
