I just got a Yashica ML 50mm f1.4 and I really don't like that it only has full stop aperture clicks. I want something that has at least one if not two clicks between f1.4 and f2, and f2 and f2.8 if possible. Anything of similar value/quality that I should look at? Any mount that works easy on my Canon 30D is fine.

My Topcon 58 1.4 and Revuenon 55 1.4 both have one click between 1.4-2.0 and 2.0-2.8.
Topcon maybe out of your price range, but you can get a Tomioka made 55 1.4 quite cheap these days.

My Minolta 50/1.4 jumps from 1.4 to 2 but there is one click between 2 & 2.8.

ALmost all the 35 mm manual focus lenses have a click between the apertures.
If you want that clicks, only one between the apertures is enough. They indicate 1/2 aperture setting. It is not necessary the 1/3 apperture click because between 1/2 and 1/3 of aperture, the difference is only 1/6 of aperture. Nothing in terms of exposure.

Now, having the F/1,4 and F/2 click indicators, do you need the F/1,7 ones too?

Why will you use the F/1,7 and not the F/1,4 or the F/2 ?

Compromise between exposure, depth of field and sharpness. I liked to use my 35mm f1.8G Nikkor at f2.2, simply because it was sharper than f2, but not much off f2.8.

On some lenses, it's probably quite possible to remove the aperture ring, and use a file or jeweler's saw to add more notches for click stops.

Or remove the ball bearing(s), makes diaphragm continuous no clicks.

CZJ PB 1,4/50 has two clicks between f1,4 and f2 and f2,8. It is not easy to confirm infinity with adapters on Canon. Try a Rikenon 1,4/55 (M42): there is one click but youn can easiliy stop beween the clicks.
