Transforming Canon EF 35-80mm f/4-5.6 lens into very sharp macro lens, preserving full AF functionality.
Did you ever wanted to shoot macro past 1x magnification with AF but didn’t want to pay astronomic prices? There are several solutions, including screw mount magnification filters, extension tubes (AF only with electric contacts) and of course bellows (without AF). Here is however super cheap and super easy solution that you might consider!
All you need is this lens:
The dirt cheap canon EF 35-80mm f/4-5.6. To convert it to macro lense you need to remove its front lens group.
It might sound complicated, but it is not. The front lens group is held on by three small Phillips screws.
Now after removing the three screws the front of the lens is loose and you can pull it out easily.
This is how the lens looks like without the front lens group
You can test the lens on something small, like those three screws. (It’s good idea to put the screws in the plastic bag, together with removed parts and write the name of the lens on the bag.)
Now you can enjoy your new macro AF zoom lens with magnification larger than 1:1
If you have any related questions, don’t hesitate to ask.

any idea how to open the canon 35-80 with the ring and no screws?
Unfortunately we don’t have that version of the lens, but try to remove front ring with the signs, either by screwing it (wit some rubber (sticky) tool, or by lifting it with a screwdriver (it might be glued only). If it was screwed in, it might release front element, if it is just a glued mask, you’ll probably find screw ring bellow.
Cheers,

Can you mount this to sony A7 with a converter?
I didn’t try it, but it should be possible
Does autofocus still work?
