Canon LTM Canon RF 100mm F3.5 Lenshood Availability?

Canon M39 M39 screw mount bodies/lenses
Two years to buy a lens hood. Hopefully, you didn't get ripped off.

I never understood why some lens makers couldn't think ahead long enough to standardize filter sizes instead of screwing their customers and forcing them to buy new filters and hoods every time they developed a new lens.
 
They lens diameters are based on the design. The design and diameters determine the speed for example. They could not design a lens at different speeds to use the same hood. it's like saying why don't car manufacturers design all cars and trucks to have the same size wheels.

Hi Dexdog and others,

Back on line after a computer crash and getting around Window 7 among other things.

There are actually 6 (4 x 34mm, 1 x 36mm and 1 x 40mm) variations of hoods for the RF 100mm f/3.5 lenses.
  1. Series VI Serenar f : 3.5 100mm (recorded) 34mm screw-in
  2. Series V1 Canon Lens + f : 3.5 100mm (none recorded so unknown) 34mm screw-in
  3. Series VI Canon Lens 100mm f : 3.5 (recorded) 34mm screw-in
  4. Canon Lens 100mm f : 3.5 (recorded) early serif in Canon. 34mm screw-in
  5. Canon Lens 100mm f : 3.5 (recorded) late serif in Canon. 36mm clamp-on
  6. T-42 clamp-on style with thumb screw (recorded). 42mm clamp-on
The serif in the "C" as in the company name "Canon" changed sometime in 1957 and that and the size is the only difference between T4 and T5...just being a collector I suppose

I didn't actually indicate in the book what hood matched the lens you may have but indicated a "T#"for that hood. Basically the hood matches the same type of info that is on the lens.

This was done in case the user or collector wanted to match that lens with cameras and accessories to make a complete kit for that era it was produced.

It is something that has interested me while collecting and using some of my gear. Peter

FWIW, here is my copy of #5 (I think)

In practice, I like the clamp on hood since it's easy to revert (hood has felt on the inside).

Best,

Roland.
