i finally finished and am happy with my conversion of the g28 into a rokkor helicoid, so i had to shoot some bench shots to properly inaugurate it.

Congratulations! Outstanding. I followed your progress, all the time wondering what was the resale value of the accumulated parts of the two lenses. I am in no way tempted to follow in your steps, but I admire your achievement all the more for just having thrown away a Minolta lens I had managed to impair beyond hope.

oh no! what happened to the minolta lens?

as far as resale value goes i spent $15 on the rokkor, a bit more than $300 for the g28, and about $10 for raw materials. the entire thing conversion was non-destructive so both lenses could be fully restored if i were ever inclined (anybody need a g28 body minus optics?).

here's a couple quick shots of the final lens:










i'll post some pics of how the aperture connection was made in the lens modification thread later.

and a couple non-bench shots with the lens:

Yea, that is sweet and I'm full up to the dome of my head with jealousy. Super nice work, Seb.

Did you take any in-the-process pics?

sebboh - lens looks great.I had the Contax 28 for a while and i agree a better focus throw will make it an awesome lens.

Great clarity on these shots. Amazing no one was killed. Different time of day and it could have been a much different story.

thanks, Partitura, it is your home city!
thanks also for the bridge collapse pictures, interesting to see, glad everyone is OK
and I really like the background blur from Sebboth, is your g28 mod a very fast lens?

ha, no it's still f/2.8 (actually the flower shot is at f/4.5). it's just capable of macro focusing now. the flower is quite tiny (less than 1cm in diameter), no idea what they're called though.

Great shots ebookman. I have been following this story with some interest, and the last shot of yours is the best shot I have seen on the internet for seeing what happened.
