The 90/3.5 close focus is very small and sharp, unique, beautiful image
quality, nice build. Overpriced for Nikon mount though, I got a Leica
screw mount version for much less though it only works around 0.5x focus
range. Should be useful on micro-4/3. Then I got a 125/2.5 macro with
Pentax screw mount that I mounted to focus from 20 feet to a bit more
than 1:1 (also overpriced for Nikon mount). I just ordered a 40/2
pancake to replace my stolen Nikon 45/2.8. I'm sure it'll come in handy.

For example?

Worthless for any camera with a changeable lens.

Do you have the slightest clue why people would be interested in a range
finder Dcam? Or a range finder camera of any type rather than an SLR?
Obviously not.

Just because -you- are happy with your latest choice (for this week)
doesn't mean everyone else on the planet would be.

The ones you snipped. Especially the point that you can integrate the laser
with the viewfinder, so you'd know exactly where it's trying to focus.

Well, that's how they work. Go pick up a Leica M or Mamiya & or Bronica R645
some time. Those are all interchangeable lens rangefinder cameras, which is
what this thread is about, I thought.

Every Nikon and Canon midrange or higher flash does it. Do you hear a lot of
complaints?
