p.1 #1 · homemade macro solution


This is a funny thing... just recently I purchased an eos 630 which came with the 1st generation rebel lens, 35-80 3.5-5.6, truly a POS (all plastic but optically OK)

I removed the front element, and now at the 35mm setting, got myself an extreme macro lens, well, I have to be real close to the subject, say 8", so as far as working room, none at all.

I just thought it was interesting that by destroying the lens, it may function as something else. Certainly not to replace any dedicated macro lens that goes from infinty to 1:1... the interesting thing also is aperture is controled electronically like any EF lens, in the shots below you'll see the images were shot at F22, 20 & 30 sec.

What do you folks think of the prospects of turning this lens into a "lensbaby" type lens? What type of lens should I use? Enlarger? Focal length...?

try reverse mount your 50 to the 85... you will be surprise how close you can get to.. a 58-58 coupler is about $10 at B&H

I have one! I never tried going from the 50 to the 85... guess I was afraid of the weight on the front element..

I tried the reverse mounting, only works from mounted 85mm to 50mm. Pretty much the same effect.

oh well.

@bellyface, how much DOF you have on F4 Accidentally yesterday I got hold of an EOS 1000 with this lens and it might be interesting for me to test this too.. But for me it's mostly flowers but butterflies as well and for the butterflies I need F4 of F5.6 to have some reasonable shutterspeeds...

can you tell me how to remove the front element ?

pretty simple, there's a small box like gap between the the lens filter ring and the lens designation (where it reads 35-80 F4 - 5.6) that whole ring comes off, then I think move the lens element counter clockwise, or clockwise, and the darn thing comes off!

as far as depth of field, the shots I took were taken at f22.... I'm pretty certain the DOF is very shallow. You'll also need to shoot at the widest zoom. And of course theAF switch needs to be put on MF...

Haha! That's great! I could never convince myself to get a decent macro, because I thought it's "too specialized" and I wouldn't use it enough.
This might be THE solution!

I have tried this with my old elan kit lens that had the AF break


I am AMAZED at the results. The only thing you have to watch out for is some lens flare...


Thanks for the idea

little bit of CA too. Of course if you want more range you'll have to opt for a macro lens.

WOW!!

I bet the 28-90 has better range, and better working space than the 35-80... how far were you from the pennies and coffee beans?

And you shot at 52mm... mhh... I think I may look into one of these...

kudos to site design too
