Sorry about that. The transition to the host and servers is moving a little slowly (perfect storm of traffic right now - at least for a little guy for me. I'm hoping that somewhere within the next few hours everything will stabilize, but I have no guarantees.

Your reviews have always been good, but this is the best one yet! Congratulations on a job well done!
AlanF said:I was really excited about this lens and have put my 100-400L up for sale in anticipation of buying it. Now, I am very worried about the Tamron's performance at 600mm. Here are more of your crops at 600mm and f/6.3. For the first, I calculate the original to have been 1100x830 pixels, and the for the second, the duck's head, 1300x1300. Their quality has put me off the lens as I usually get very sharp images at those sizes.
For comparison, I have shown a sparrow of similar original crop taken with an SX50 at 1200mm equivalent (it's not the best quality) and a shoveler duck's head I took a week or so ago with a 70D and 600mm lens.

Is that a $12,000 lens you're comparing this $1k lens to? Not exactly a fair comparison. Plus, your statement doesn't really make sense...how this guy performs at 600mm should have no effect on you selling your 100-400m.
AlanF said:If you think the comparison with an expensive lens unfair, what do you think about a $300 SX50 giving better performance than the $1100 lens, with a whole camera for a third of the price?

This remains to be demonstrated.
I don't see the review, because the site seems to be down for me. But I do see that the pictures you are comparing to are shot with much more favorable lighting than the pictures you don't like.AlanF said:Albi86 said:AlanF said:If you think the comparison with an expensive lens unfair, what do you think about a $300 SX50 giving better performance than the $1100 lens, with a whole camera for a third of the price?

Based on the crops of the birds shown in this review, it has been demonstrated - just look at them, they are unacceptable (to me, but maybe they are acceptable to you).

But, if those photos are just very poor examples and the lens can do much better, then I will of course change my mind with enthusiasm and buy one.

how long do you take pictures?
noticed that your images with the SX50 are taken in bright harsh sunlight as it seems.
the one crop from him you showed not. seems like a dull overcast day to me the image was taken.
im still unable to read his review. now i get a blank hoster page yesterday it was 404.
but i will have a look at the review if possible.
fact is, who compares this tamron lens to a 600 f4 has much to learn.
people with a signature as long as yours should know what they can expect for 1000$
I have an SX-50. For what it is, it is insanely good and you can handhold it at the equivalent of 4800mm (50X optical Xoom plus 4x digital), it easily out resolves any lens I have on distant objects and it is very low cost. The autofocus is terrible, shutter lag is huge, and forget about having a burst rate..... I would not consider using it on a moving bird...AlanF said:Lichtgestalt said:AlanF said:I was really excited about this lens and have put my 100-400L up for sale in anticipation of buying it.

I was comparing it "with" another lens and not "to". And, it was not a 600mm f/4. The duck's head taken with the Tamron was in perfectly good light and you can see that it is soft, irrespective of any comparison..
Don Haines said:Funny you should say that.... I have a Snowy Owl hanging around and hope beyond all reasonable hope that by the time my lens (pre-ordered a month ago) arrives, that Snowy will still be around....TWI by Dustin Abbott said:TrabimanUK said:Cracking review! However, from my perspetive, I'm still interested in focussing on BIF when at 600mm. I'm not a birder, but if it is good for BIF, it'll be good for cheetah and other big cats running.
Just need someone to review that and if it's as good as the rest of Dustin's review, I might well get one.![]()
Unfortunately BIF is hard to do this time of year where I live in Canada. There just aren't hardly any birds around! There also isn't any open water right now that might attract waterfowl. I'm afraid someone else will have to provide that kind of testing.
Even funnier, as I am waiting for a LONG!!! lens for birding, I was wandering around yesterday shooting Chickadees at 24mm.... yet I use them as justification for 600mm....
