i really want to get a macro
but until i save up the money
and find one
i did a macro the cheap way
reversing a 28mm lens on my 50mm lens
the flower would be about 5mm across
i need to practise a bit more
and choose a lighter time a of day too i think

john,
you'll find it a lot easier in all respects if you just use the 50mm reversed by itself. you can make an adapter using a body cap and a step up/down ring. it's a piece of cake. ask if you need directions. i've done the two lens thing and can assure you the sigle lens setup is the best. well, for me..

have you thought about screw on close up filter kit? I got these of the ebay for under $25 cad.

istDS Pentax SMC FA 28-200 f3.8-5.6 1/[email protected] f4.5 iso200 @ 50mm +4 filter used.

of course, there's a lot of distortion inherent with these filters.

thanks Robar
i tried just reversing the 50 on the camera directly
but it didnt get as close

i am just playing around with this at the moment
and need to work out the best way to go about things

i had another go today with the 28 reversed on the 50


this is the full frame


i do have diopter lenses too
but this was more fun
lol

Why don't you use an extension tube set? You'll get closer images and won't lose any optical quality like you will with close-up rings, and you'll have more versatility than just reversing the lens.

I just created an automatic extension tube (no AF but preserves the auto exposure modes) by removing the lenses from a mediocre Takumar-A 2X teleconverter. Since I have had the DL the limitations of this teleconverter have been far too obvious, so I haven't been using it. However, as an extension tube used with either my M50mm f1.7 or even the A 70-210mm f4, it may find a new usefullness.

Don't worry Roy, as soon as I try it with the zoom I will post results.
