Need some help with my new CL

[back alley]

the cv 28/3.5 would be easier to find, new at least.
not too sure how they compare with the kobalux but on their own they have a great rep.

I'm not sure that's correct. I'm pretty new to this, so I could easily be wrong, but it looks like the meter is behind the lens. So it's getting whatever amound of light passes through the lens. So, by my logic, you can get to it's minimum effective range by closing down the apperture. But like I said, I'm new to this and I might not be understanding it correctly.

Glad it's working well. It sounds like the meter is working OK, but you sometimes reach its sensitivity limit. Naturally, a faster film will solve your problem in low light situations.

I did a google search on that kobalux 28mm and it seems like a really good fit for the light and small cl set I'm trying to build. I can't seem to find any for sale on ebay. Do you know if they're still being sold somewhere?

None are available new that I am aware of. Instead, I'll put in a good word for the Canon Serenar 28/3.5 lens. I just recently got one on extended loan and so far I'm loving it. The whole VF area on a CL covers the 28mm FOV quite well, I find, so I'm not using an external finder.

The only real issue is if you think you'll find f3.5 too slow. The faster 28's get to be many more pennies quite quickly... 😱

Hi Andrew

Hi Andrew

I think there is a possibility of this going on. Assuming the photo-electronics of the cds cell are working, the cell is on a mechanical stalk behind the lens, and could possibly get "less than designed" light readings at smaller apertures if it were not in the optimal designed position.

Not that I've owned one but surely the problem here is that unlike the meter on my Olympus SLR's the CL is not metering at full aperture but at taking aperture. So though f2.0@1/60 may be EV8 and read OK it won't work at EV8 if that is f8.0@1/4.

Or have I misunderstood it?

The CdS cell will measure whatever light falls on it. In some cameras, though, for example my Canon FTb, for every film speed there is a slowest shutter speed beyond which the camera shows a red flag. In cameras which take readings at the maximum aperture of a lens, there is usually a means of communicating to the circuitry both that aperture and the one which is set. Since no metering system can be called ideal, the cell-on-a-stalk of the CL (and the M5) can certainly be called less than optimal by some. However, Leitz are not known for making asses of themselves, so it seems likely that they chose the best compromise available. The stalk is of course inherently prone to failure and damage.
