My technique to focusing in extreme low light

I just zoom in focus it and then zoom out to my original frame like i use to do when i was a tv cameraman. Does anybody does that to make sure your k20d is in perfect focus?

Vic,

I do that with my K100D.
I did that with my Canon T90.
I did it with my Canon Ftb.
Also with my Exakta VX IIa.

There is nothing new under the sun.

Someone ELSE used to own an Exakta?!?!
Wish I could remember the exact model (no pun intended).
Great little camera that I "cut my teeth on" photographically speaking!

With some of my lenses this works (the DA* 50-135 for sure), but with others, the focus needs to be adjusted differently at different focal lengths.

The only problem with zooming in under low light conditions comes if your zoom is not a constant aperture. If it is a variable aperture you're actually making your viewfinder darker when you zoom in.

I sometimes put a small LED penlight next to my subject, focus on it, and retrieve it before shooting. If the subject is close enough I just shine it on the subject while focusing.

Used to? You guys don't still have one? I do (a VX) and you can quite literally cut yourself on that beast.

For me:

Zoom = a slow autofocus lens I wouldn't even try to use in low light

My low light lenses are all primes - and mostly manual focus. So I have to admit I scratched my head a moment before figure out what the OP meant :-)

I tried this with a 16-50 when I found that I could not see to manually focus on infinity whether in poor light or sunlight. Of course it didn't work;the point of sharpest focus varied from 16mm to 50mm . At 16 mm the cursor had to be set between the lemniscus and the 7m mark to obtain sharp focus whist at the other end it was set on the second lobe of the lemniscus. Other settings were: 20mm,first lobe,28mm and 35mm dead centre.Departures from these settings produced noticeable degradation in focus . And so any point of focus towards the wider end can be a little hit- or- miss. But then those of us who have come to know (and love) the foibles of our 16-50's,know this already.

You have to be careful with that technique if you have a one touch zoom focus ring, the pull a twist gremlin is alive and well.

I still have my Exakta VX IIa that I purchased new in 1957.

I still think it is an outstanding camera.
