Zone focus on 35mm skopar 2.5

[Moogie77]

Hi KO and Press[ass,

Thanks again for the interesting and helpful comments.

Anyway I am now still in China, a colleagues brings my "new" purchased LTM and RF camera with him in 1.5 weeks, returning from holiday.

Then I can first try the LTM on film and I am already pretty much looking forward to it.
Presspass exactly how you described it, is the technique I want to practise and learn.
I realise now it might be a good idea to stick to the LTM and use it till I learnt how to use it properly. Attach it to a digital camera is another story again? Only because of the crop factor or any other limitations?

Cheers, Miguel

Knob, nipple, pin - you will often use two fingers, to hold it in between and move guick. Concave - you'll just need one for quick street photography. Two will works as well 🙂
Depends how smooth focus ring is.

Digital is no difference if on Leica M or Epson R-D1. If on Fuji, Sony... I'm not expert on these and what I see from experts is not for me.

I think you've got the basics, but take it one step further by feel;

I tend to get to know where 0.7m, 2m, and 5m is on the focus tab (0.7m and 5m are about equal movement either side of straight down). At f/8 it's not often I need any more accuracy than that and I can quickly grab anything. I find it easier to judge distance as 0.7m is arms length; 2m is where my head would hit if I fell; and 5m at f/8 covers so much ground I use it for "far but not infinity". For a long way away I can jam it to infinity.

So this question was from 2013. Oh well.

For the new question that dug up the thread, concave is my preference. I find it easier to move either way without moving my finger to the other side of the know.

But for the same reason you prefer the concave I prefer the convex tab of my version 4 Summicron 50. With the concave tab on my v 4 35 Summicron I don't have the same control with my finger at the only possible angle in the depths of that concavity so I am using the two ends of the dip and find it's slower changing direction. I am coming around to the Zeiss 'bumps'.

As to DOF I came to the central finding of The Ins and Outs of Focus intuitively, particularly focussing on infinity. If I have a wider aperture and want an object in focus I have learnt to determine the distance pretty well and go there quickly with focus tab feel when there's a hurry. I am rarely using hyperfocal distance focussing therefore.

Hi KO,

Yes, I will just try it out and see how it works.

Currently I still try the same with my EOS M3 and the 22 mm prime.
Without success, I always need a tree or something to pre-focus on the distance I want.
Also the focus ring seems to be kind of digitally adjusted. After switch off and on it changed completely...
But coming back to the original topic, with adapter ring I also want to give the LTM a try on the EOS M3. Let's also see how this goes.
