Is there any way to punch in (magnify) to get critical focus through the standard viewfinder or the extension?

 

The SRIII has a switch on the extension tube I believe. This would be really helpful!

I don't know of any, my SR book doesn't mention any such button or accessory.

Simple answer zoom in to focus or use a tape measure from the film plane. It's marked on the side and might have post to hold the tape measure.

Have your zoom lens tested thoroughly to make sure it holds focus throughout the zoom, especially if it has been adapted from another type of mount. If it has then this is the time honored and easiest method to get sharp focus on SRs with a zoom.

I do not use zoom lenses unfortunately! I use MKI Superspeed primes.

 

I ran my first couple of mags through camera and was able to pull focus hand held, walking etc with only a few a couple of fails. I favor wide angles so I was mostly on the 9mm which was pretty forgiving.

 

Slowly getting the hang of the viewfinder.

Are those extension tubes not interchangeable? You might benefit by having Bernie O'Doherty laserbrighten your ground glass.

There was an after market eyepiece marketed by Kish Optics that would provide greater magnification.

Might take a bit of searching to find.

Great ideas. The viewfinder is a bit foggy I think, I did not know it could be cleaned up.

It really depends on what is causing that fog. If it's just dirt or smudges on the outside glass elements then you can clean them just like lenses. Be careful because this glass scratches a lot easier than a coated lens. Often times on these old cameras, the viewfinder optics get scratched all to hell over the years by overzealous users in the field grinding grit and sand into the glass with their shirt tails, pocket handkerchiefs and whatnot. So that may be what is causing the haze, though hopefully not. If the haze is between elements or deep inside the optics then you'll have to send it out to a service technician to be professionally cleaned.

In my American Cinematographer Manual on page 186 there is a Depth of field calculator, that will help you determine what will be in focus. It looks like a 9.5mm lens at 5.6 with the focus set at 4ft, everything 1ft 10in to INF should be in focus.
