Yes the teleconverter seems pretty good when doing close up stuff but I must admit it is total pants when used for long shots, the photo seems to come out very hazy, almost cloudy tbh.

Took some photos with just the lens on its own today.

Very impressed with it.

If it is the APO version I did read somewhere that they can only be used with Sigma lenses, and only certain ones of those at that.
That's why I went for the Tamron 1.4X.

May be totally wrong though, it has been known

Edit reason : Missed an "F"

Now that my new Tamron SP f3.5 70-210mm is working with the PKA mount I decided to take it out for a trial this morning. Usual park in the local town of Guadamar where there are ducks and stuff.

Personally I think it did a much better job than the Sigma 135-400mm DG APO even with the cropping.

Unlocker has the Pentax version for sale in the appropriate section unless he has already put it on Ebay. (18-250mm)

Now that the Tamron PKA mount is fixed and working I have got the lens on the camera and having a play. Nothing special but these 2 were taken not long ago, both have the 2X 01f Tamron teleconverter attached and at maximum magnification.
First one is at 70mm (140mm) and second is at 200mm (400mm).
Im certainly not used to standing that far away when I do a macro shot but the results are not bad imo .. both uncropped.







And just a quick shot of the dog at 210mm with no teleconverter




I think I will enjoy using this lens

Arghhh, why have you done that.
I had resigned myself to waiting for the 60-250mm DA* and now you have me thinking again.

That looks better, a bit sharper to my eyes.

Yet you say above you are keeping the 24-90mm?
Anyway, I'm not bothered which brand you decide on, go for whatever makes you happy I always say but if you decide to offload the 100mm macro (and don't mind sending to Spain ) then please give me a shout first

Must admit I quite like the look of the D700 myself actually.

SORTED !!!!

After you pinted out the wear I had a closer look and then at the mount.
Went to Ebay and managed to find someone selling a PKA mount (expensive little buggers arent they) who had photographed both sides in a decent size.
From there I could see the actuator on mine was at a different angle so pushed it back at touch and it closed the iris a bit on the new lens, so then pushed it all the way back and now everything is working fine.

Many thanks for your time and effort Daniel.
Appreciate it

Well I didn't say it was a GOOD moon shot
