Basically, I want to put an old lens on a new camera. M54 would need an adapter. but as I have not or could not buy what fabriqué ..... but...HOW??
I show you how!!
Step 1: Dismounted
Remove the back of the 58mm. on the picture you can see a 300mm lens that dismounted the back so you can place IN the 58mm.
Step 2: Plastic rings
measured with caliper and see which gives us a measure of 1.18 mm. this means that we have to cut it after sanding and reduced to 1mm.
well! we already have our rings, now sanded. well sanded! (remember. .. each with 1mm)
Step 3: Lace and cut
the other ring cut into 3 parts so that we can create a lift and screw the adapter 300mm.
Step 4: Locking the diaphragm
we do this with an elastic band so that we can open and close the ciafragma manually later.
(this is because the anchor will be completely covered and we will not be able to work it from the command of the camera) is obvious! hahaha
then to lock it with a rubber band we get from the outside aperture control ring light we can have it in "semi-automatic mode" hahaha
Step 5: Glue
embedded and cut once, we will measure the position of the screws 300mm adapter and paste parts of ring cut into the other ring is positioned on the 58mm adapter.
