bellyface Offline Buy and Sell: On Registered: Mar 17, 2003 Total Posts: 4162 Country: United States 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...? some examples: - - - - - - these are hi-res jpegs - - - - - - - - shot of "diet rite" soda can at f22 shot of cereal box F22 Edited by bellyface on Jan 11, 2005 at 03:45 PM GMT Edited by bellyface on Jan 11, 2005 at 03:46 PM GMT Jan 08, 2005 at 09:56 AM

mikekiwi Offline Image Upload: Off Registered: Jan 31, 2004 Total Posts: 35 Country: Netherlands Re: homemade macro solution @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 ?

bellyface Offline Buy and Sell: On Registered: Mar 17, 2003 Total Posts: 4162 Country: United States Re: homemade macro solution 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... Jan 09, 2005 at 04:52 PM

LOL 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! :) Jan 09, 2005 at 10:25 PM

kawter2 Offline Image Upload: Off Registered: Sep 11, 2004 Total Posts: 153 Country: N/A Re: homemade macro 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 Jan 09, 2005 at 10:49 PM

bellyface Offline Buy and Sell: On Registered: Mar 17, 2003 Total Posts: 4162 Country: United States Re: homemade macro solution little bit of CA too. Of course if you want more range you'll have to opt for a macro lens. Jan 09, 2005 at 10:57 PM

kawter2 Offline Image Upload: Off Registered: Sep 11, 2004 Total Posts: 153 Country: N/A Re: homemade macro solution I was pleased with these, havent been able to get light from flaring @ 90mm yet http://ericcotter.com/blog/index.php?showimage=62 http://ericcotter.com/blog/index.php?showimage=61 Jan 09, 2005 at 11:37 PM

bellyface Offline Buy and Sell: On Registered: Mar 17, 2003 Total Posts: 4162 Country: United States Re: homemade macro solution 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 :) Jan 09, 2005 at 11:46 PM

primedigital Offline Image Upload: On Registered: Sep 03, 2004 Total Posts: 394 Country: United States Re: homemade macro solution Hey bellyface. That's a pretty awesome discovery. You are full of surprises. I was surprised to run across a post from you. Thanks again for all the effort you put into saving my cf card. I just wish I had a cheap lens to tear apart and try this with. Best regards. :) Jan 12, 2005 at 02:51 AM

bellyface Offline Buy and Sell: On Registered: Mar 17, 2003 Total Posts: 4162 Country: United States Re: homemade macro solution Hey Glenn! No problem, I tend to think of this place like a relative's house... helping each other out... Now I'm not to familiar with the other 35-80... I'm guessing the lenses released with the first series rebels will probably work best. The way they snap apart on the front lens element. Maybe the 80-200 rebel lens will work best... not sure... but I'll find out :) Jan 12, 2005 at 03:32 AM

bellyface Offline Buy and Sell: On Registered: Mar 17, 2003 Total Posts: 4162 Country: United States Re: homemade macro solution found a trashed 35-80 III on ebay, again I can't confirm if the front element can come off as easily as the original 35-80 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=30033&item=3865381348&rd=1 the other thing I'd like to know is working distance... I have a theory that this kind of macro set up works best with wider zooms, so it might even work on an ef-s 18-55 kit lens. At the widest setting of course. It seems logical that the front element will extend focus distance out to infinity, so removing it will in essence "show you the raw picture" ...pardon my ramblin :twak: Jan 12, 2005 at 08:32 AM

bellyface Offline Buy and Sell: On Registered: Mar 17, 2003 Total Posts: 4162 Country: United States Re: homemade macro solution I found another (af not working 35-80) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4687&item=3865725114&rd=1 the max I'd pay for this fine specimen would be $10 - $15...
