The only reason I would choose the Pentax over the others is for the Quick Shift which imo would come in very handy on a macro lens.

Apart from that I would say there isn't a duff macro lens out there.
My favourite and the one I use most is a 30 year old 100mm 1:1 Vivitar f2.8 and I seem to get pretty good results with it.

I also have an older Tamron 90mm f2.8 1:1 Adaptall 2 macro which is again excellent, much lighter and easier to focus than the Vivitar but doesn't seem to give the same quality of colours and bokeh.

I have a 50mm Sigma macro lens as well as a Vivitar 100mm and Tamron 90mm.
To be honest I never use the 50mm as it is just too short for most things, if you want it for bugs and insects then something in the 100mm range would be far better but if you are wanting a lens more for the wide aspect with that added advantage of macro then the 35mm would be the one.

As for the Sigma 17-70mm is is a nice lens but is not 1:1 like the others so you are not getting a true macro lens.

Best night is usually a Sunday evening around 8pm, that is when I used to finish all my mobile phones as Friday, Saturday most people are out and a lot do not look on weekdays.
Sunday evening is pretty quiet for TV as well so a lot of people go looking through Ebay for something to do.

At the moment I suggest not between 8-9pm because Top Gear is on

My 2 screens arrived this morning and all I can say is WOW!
After getting finger prints and dust on my old screen while trying a cheap chinese split jobbie some 5 months ago I have to say its funny what you get used to.

Its nice to be able to see the world again ...

I will try it when I get back to Spain as the 360 is over there.

Mine arrived this morning, looks a bit better than my AF-360.

Will the £100 cashback also be available on the GPS version?

Thanks.

Ahhhhhh .... Thanks to all, especially Unlocker for the link.
Worked like a charm ... now to try out the tubes attached to bellow with a 50mm 1:1 macro lens attached.

Actually, that will have to wait until I get back as well.

Matt.
Have tried all 3 tubes on their own and still the same, the F is no longer flashing and they work fine in manual mode.
Still getting F--- though so cannot set aperture via camera body.

I will upload a couple of pictures of them when I get back to Spain, cannot do any from here as the laptop I am using is older than the ark.

They have the electrical contacts.

Custom function is already set for my "M" 50mm macro and K mount 300mm f4
