Sun Wide Zoom 24-40mm 3.5 Macro

Price pair 2017 --> 20 euros

What a good surprise !
This lens became one of my favorite. Soft in the corner, sharp in the center, perfect for me.

Construction is perfect, feel heavy and solid, a nice piece of craft.

Why I decide to make this mod ?
because lenses are very cheap, and I saw samples test before and I found them astomishing, see by yourself :

The problem, you found many lenses with element separation, this is not a big problem, this is purelly aesthetic, there is little to no impact on the final image.






This MOD is for Zeiss Ikon Contaflex III and IV, other model are possible but outer lens diameter are different so you will have to figure out how to do it.

Contaflex super I think vs contaflex III - Back view different diameter




Contaflex IV




The rear lens element is bond to the camera, we need to remove it.




Disassembling is easy, just unscrew all what you see



















The MOD



1. Lens
2. 55mm female - 52mm male
3. Helicoid  M52 female - M42 male 17-31mm focusing ring
4. Slim M42 ro NEX



SHUTTER DISABLE
No need to open the lens there is a simple way to do it.
Just glue the shutter gear, cut it when it is permanently bond.






Turn the gear to activate the shutter, realease while holding it.
Once you ear the clic sound from the shutter, still hold the gear
go back a little, stop when you see the aperture blade (f8 is best) barely move.

Hold until it is bond. trust me, this is a permanent bond very very strong, I glue broken tripod with Penlock GTI, it is so so strong...

You can decide to cut the gear, or not, I didn't cut it, I may paint it in black.







Trim the inside thread of the 55mm part, you only need a blade cutter
it will perfectly match the outer diameter of the lens.





Then screw to Helicoid, adjust, triple check, cement, enjoy.



WHEW, Final assy Awesome, smooth focus, with that helicoid.
