Using manual lenses with the GH-1

[j1clark@ucsd.edu]

I recently got official 'permission' to use the Wife's equipment... it only to a couple of years... anyway...

Here's the problem.

I was testing her 17-35 f/2.8 Nikon lens, which with my adapter, seemed to work 'perfectly'... except for...

I can't recall how to enable the 'magnify' mode when depressing the shutter... which is in the manual... but since I'm asking...

But the 'real' problem is the fact that when I open the lens up to focus, f/2.8... the LCD is so blown out in normal lighting I can't focus worth a damn anyway.

I'd hate to have to have an ND filter on hand to just deal with focusing... is there some way to 'correct' the lcd display?

The manual focus assist does not work on manual lenses, you will need to use the other manual focussing aid ( i can't remember the name of it). When you press the left selection key, a small square appears, hit the menu key and the screen will zoom in, helping you to focus. Its essentially the same thing as you are trying to do, only it't not automatic.

I'll try that. What about blown out LCD when focusing with the aperture wide open.

It sounds like your image is over-exposed. If you are set on shooting at f2.8 then you will have to increase the shutter speed to lower the light. Either that, or get a nd filter or lower the light level in the location you are shooting. I don't know why you would have to open the lens up all the way to focus, though.

Uh?

Focusing is always done at 'wide open' even if it is hidden from you via Automagic focus.

I think I have figured things out... When in 'movie mode', the LCD/EVF seems represent what is going to be recorded, give then ISO and 'wide open' state of the aperture... which seems to be 'blasting'.... In Manual still mode the display is automagically adjsuted, and so the display is toned down from the scene light levels.

So, the method I'm using is switch to Manual Still mode, focus, then switch to movie mode, set the f-stop value, release shutter...

Why 'focus wide open'... because that is the point at which Depth of Field is at a minimum, for a given lens, and any apparent 'sharpness' due to DoF is also a minimum.

This would not have happened on a 'optical through the lens' camera, since the light levels would be exactly what the lens received, and passed 'wide open'.

On older cameras, there would be a button on the camera, or lens depending, which would force the lens to 'stop down' so one could check DoF more accurately...
