Cheers! I've managed to sort it and catch in focus now works ! The paint on those tubes is definitely tough though.

Time to test it out.

Thanks again.

Welcome, go Pentax !

SRS Microsystems is an excellent company if you choose to buy from them - I bought my camera from them and they are a great in all aspects, fast delivery and prompt replies if you email them.

There is the classifieds here too, I think there is a used K-5 up for sale at the moment.

Best of luck.

Those are very good.

Presumably these aren't cropped, then, or you would have left the legs in! Just reduce the number of tubes to lower the magnification. You will still be able to crop if you need to without any loss of detail.

As for catch in focus with the tubes you might need to check the mounting plate of the tube to make sure it's connecting properly. I have a set of Vivitar tubes which were coated in a nice coat of matt black paint. Neither the stop down metering or the catch in focus worked until I cleaned the paint away from the contact point. It's a common problem and the most likely cause if catch in focus works o.k. with the lens on it's own. I have a Pentax branded 50mm tube with a nice shiny plate which worked fine immediately.
Cheers mate . I cropped a little bit but only a couple of mm.

I'll try that next time, I really wanted the whole spider in the image, but I needed just that little bit more room - I probably should have swapped the 20mm for the 12mm. Nonetheless I know for the future pictures.

That's exactly what mine is like, its fully coated in a thin layer of black paint...Is it safe to lightly sand it down? As the 50mm on its own does work with the catch in focus.

Thanks again!

I wanted to try out lower ISO and f16-22...So I just went out in the dark with 3 lights and got these, pretty happy now ! Only thing I'm a little disappointed with is the legs being cut out of the picture.

Hmm I just tried to use catch in focus but it wont work with my tubes .

I do have another old lens which I picked up the other week, so I might give that a try next...Its pretty heavy in comparison to the 50mm though haha.

Cheers mate. I'm actually not quite sure I left the ISO on so high, I think I'll give it another go with the ISO on 200 like you .

I love how sharp your image is...Poor fly too haha!

I'm using the K20D with f1.7 M and Vivitar tubes x3 for 68mm.

Arghh I forgot that my camera had catch in focus, I'll have to use that too !

First attempt at using a manual 50mm with extension tubes. Its not very good and I left the ISO too high though ...I think it might be wise for me to use a tripod next time too.

This guy attacked my lens which was great to watch!
