Why not get one of the 3rd party adapters (see the thread on shots with these) and put a 50mm k mount in your pocket to give you nearly 300mm 35mm equiv in case you see the odd bit of nice wildlife?

I've recently got the same Tamron version for the same reason as Vic. I'm quite impressed with it so far to be honest.

That is quite a good price for one in good condition. They generally go for about £25 - £30 on Ebay.

Not far from perfect taking everything into account. Impressive.

A glimpse of brightness today allowed me to get down to 1/400th sec and Iso 250 with the DA*300mm on F4. This was taken from inside my lounge with the patio door open. Naturally the Blackbird was undisturbed as I paced it later to be 20 metres away. This was cropped to only about 35% and got sharpened in down scaling although it was very sharp to start off with.
I am finding this quite astounding really - 1710mm at F4, quite a pricey lens I would think



Believe me it looks even more impressive unscaled at full screen!

Which make is yours John? Mine is the RJ one.

I read on the other forum that this model and probably others have a satin interior finish that caused some internal reflections. He said his results improved after doing this although I couldn't verify this. As it was so easy to do with a little tin of Wilkinsons water based matt black paint i went ahead.

Can I just bump this please?

Well mine arrived and I duly painted the inside matt black as recommended elsewhere. The sun has not been out once since it arrived but that of course is the norm when a new lens test is required. So - this is with the DA*300mm and Q, on a tripod with remote, about f5.6 and ISO 400, from about 30 feet. Virtually no cropping but usual adjustments I would do to any image, especially one taken in the gloom.
Not bad in my opinion.




Quite a few out of focus but wagtails don't stay still and only about 1/100th sec possible so to be expected.

First time when you were there you mean! Bad luck
