I don't know about their SD cards but Crucial make great memory cards for computers. Stick "Crucial" in google and have a look at their website.

I was very undecided between the 105mm and the 70mm, but decided on the 70 as the best compromise. I still have my ext. tubes which I like to use with my 50 and 135, but the 70 sort of drops in the middle and is better for hand held outside work than setting up with tubes and the limited focusing distance that that brings. Even with the little time I have had to play it is easy to see how liberating a dedicated macro lens is. The 50 was too limiting for the use I want.

Thanks everyone, I am not considering AF as a buying point, I have found for most critical stuff I turn it off anyway. Your replies here and other comments elsewhere about there being no bad macro lenses has eased my minds so I have bought the 70mm. When the bugs arrive on the scene in spring I will (might) show you the results.

Thanks again.

Sigma state that the minimum focusing distance is 25cm. Surely that's OK.
Using a 135mm with 65mm worth of ext. tubes I can focus down to about 36cm which leaves more than enough room to be comfortable. What about the Sigma 105mm macro as an alternative (or anything else for that matter) ?

Does anyone have any opinions/experience of this lens? I have read a good review on it and can get one for £219 from a UK supplier.

I can look past the watermark and I don't blame you for including it. Some years ago was a keen flight simulater fan. During the period when Microsofts Combat Flight Simulaters 1&2 where current I produced many paint jobs for current and new add-on aircraft as well as aircraft flight characteristic files. I bought an aircraft add-on package from PC World to find when I got it home some of my work on the disc!!!! Needless to say I got nothing out of it, because the cost of going to court etc was prohibitive.
I did not do the work for money, but as a hobby, but there was about 200 hours of work on that disc that someone made a bundle on.

At least you did the right thing by giving him more than he asked.

At least we can look forward to going to work tomorrow

Next time I'm coming back as a bug in Clarky's back garden. And just as he shoots I'm going to jump out the way

Who mentioned Murphy? That has inspired me to get a few cans of the stuff and spend Sunday afternoon getting drunk, seeing as it's too late to go out and it's raining anyway now, so why not.
