"The Tamron 70-300mm f/4-5.6 Di VC is surprisingly good optically. It is merely a little bit less sharp compared to my Nikon 300mm f/2.8 AF-S, stopped down to f/5.6."

"This new telephoto optic from Tamron has proven itself to be very capable indeed. It is capable of producing images with very good resolution across the image area at all focal lengths and optical aberrations such as colour fringing and distortions are kept well within acceptable thresholds."

Ok you finally persuaded me John
Just ordered one for the 50D as it's the last day of the £30 cashback.
Will let you know what it's like when it arrives.

I'm 100% certain that the DA*300 is capable of much better shots than the 55-300, but don't underestimate the sharpness that the zoom is capable of. Use it at around F8 with high-ish shutter speeds and you will be surprised just how good it is.
On your woodpecker shots, the only conclusive element is the colour rendition which is better on the DA*300.

You are of course quite right John! I should have gone for a much higher ISO - I have yet to come to terms with the noise suppression abilities of the K5...

I have posted a couple of self-explanatory shots of a woodpecker. I still think it reasonable to say the 300* is 'a bit' sharper than the 55-300 (at that range).

2. DA* 1.4x/1,7x SDM rear converter.
3. A DA 70-300 f/4-5.6 SDM with performance to match the Tamron 70-300 Di USD, with similar build to the DA 17-70.

Review here
Think I pretty much agree with it.
By 300mm, this lens delivers poor image quality across the frame (except on the far left side of the frame). Stopping down at 300mm helps, but even f/11 image quality is only marginal. If you consider this a 70-200mm lens, you will be more happy than if you are counting on getting great 300mm image quality.
