Leave this lens alone! It's rubbish.

Hi-jack Ebay?

With this crew we can pirate some K20's

What you need to do is take some macro pics of something with 2 legs

OK, OK

Extension tubes are a great way of turning a lot of lenses into macro lenses. With a 50mm you can get really close, but the lens may shade the subject. 2 examples I took when trying my then new camera with my old kit.
Cosina 50mm with 65mm ext. tube kit:




Cosina 165mm with 65mm ext. tube kit




My little kit splits into three seperate tubes of 13mm 21mm 31mm which give 3 different amounts of magnification.
I bought them about 25 years ago and they were quite cheap.
I have just bought a Sigma 70mm macro which should arrive tomorrow, which I am hoping will be quicker and easier to use, but as for sharpness.....

WOW

My friend has bought an Olympus E410 cheap from Asda, and he has got 5 Pentax lenses sitting doing nothing And he can't understand how to work it, and he won't read the book of words. I don't go out with him if he suggests a trip to take some pictures. Victor Meldrew or what?

Moving from a pentaprism MX to a pentamirror K100 I didn't notice too much difference ( the only thing I really, really miss is the split prism focusing screen). What do you gain with the pentaprism?
