For a while I have been contemplating some macro photography...

I have looked a few lenses and seen some of the prices

I was wondering if it's worth getting some macro extension tubes and have a play with them first? (Not sure on how they work neither as never played with them so tips would also be much appreciated!)

Cheers,
Ian

I actually agree...

I have another version on my website on the Motorsport gallery!

Is this any better?

I echo Johns sentiments...

I use a Sigma 500mm mirror on a K ring and its a great little bit of kit. Can't remember how much it was as I have had it for years.

It was actually taken in portrait orientation with it in the vertical. It was being lazy when I did my online portfolio because I wanted them all in the same orientation and have the same size to keep it neat!

A few have voiced they don't like it but most do and more importantly so do the team! I try and shoot some different perspectives compaired to other motorsport shooters. Most of the time they only use landscape and keep the images in the horizontal frame. It's nice to try something different!

I use the Sigma 150-500mm and I use the full length of it but most of the time I am using 150 to 400 mark. It depends on the cars/trucks and the speeds they are travelling at as to what shutter sped I use.

I rarely if ever go above 1/400th. I am normally hovering in the 1/200th to the 1/320th mark. The only time I normally jump up to the 1/400th mark is if it's a fast class that I am getting a head on shot of.

PS... I have even hand held this lens down to 1/90th at about the 250mm'ish mark!

Some have you have probably read about me banging on about panning and shooting racing....

So I have decided to put a few of my shots up for you guys to have a look at.

Hope you like them!

ON the K20D you can adjust for front/back focusing lenses.

I don't know if you can on the K10 but have a look in the manual or menu on the camera and check.

If you go HERE and have a read and download the chart!

It may help some.

Yes it's HSM!

I did say in the post you put about the lens

Clarky... The bugger is heavy! The difference between the two is pretty negligible... the 150-500 is just under 1.8kg and the 50-500 is just over it.

It can knacker you out lumping it about because with the camera on it weighs not far off 3kg!!! I've taken it off after spending a day walking round a race track and it feels like someone has got off my shoulders!

I only hand hold it as using a monopod or tripod is to restrictive when I am panning.

It does come with a great sling that keeps the camera in a great place to just grab hold of it.

ok come on....

admit it, who thru up on the camera?
