Choice of focusing screens on the 1DX
« on: January 11, 2014, 03:47:36 AM »
I know this has been debated elsewhere, but I got lost in all the threads.

My use of manual focus for the last years have been limited to tripod mounted tilt&shift or macro, primarily using live view. But since I got the Otus and now also the 15mm Zeiss, I need to improve my ability to focus manually through the view finder. I am also eagerly awaiting the next Otus family members, having seen the phenomenal quality for the 55/1.4, so manual focus may be more and more relevant for me.

I currently use the focus indicators, but that distracts me and shifts attention from motive to focus. I would therefore like to have a precision matte focusing screen for that purpose and I believe the Ec-S may be it. I thought Canon didn´t support that for the 1DX, but according to B&H they do.

So two questions;

1: Does anyone have experience using this focusing screen with the 1DX and is it any good?

2: Since I don´t want to swap focusing screens back and forth, is it still possible to use an f4 or f5.6 lens (like the 600 4L or 200-400 with the extender in) with the Ec-S in place or will the viewer be too dark and grainy?

An alternative could be to get a 1DsIII body for use with the Zeiss lenses, but I am not very tempted by that option.
5DIII, 1DX, 8-15/4L, 16-35 f4L IS, 24-70/2.8L II, 70-200/2.8L IS II, 70-300/4-5.6L IS, 200-400/4L IS 1.4x, Zeiss 15/2.8, 17/4L TS-E, Zeiss 21/2.8, 24/3.5L TS-E II, Sigma 35/1.4 Art, Zeiss Otus 55/1.4, 85/1.2L II, 100/2.8L IS Macro, Zeiss 135/2, 600/4L IS II

The Ec-S is physically compatible, the only issue is that there's no firmware support for it to correct for the altered metering. In theory, Canon could provide that with a firmware update.

I haven't used the Ec-S with my 1D X, but I used the Eg-S with my 5DII.  It was generally fine outdoors with f/5.6 lenses.  Indoors f/4 was ok, f/5.6 was a bit dark but usable in a pinch.

  • Great gear is good. Good technique is better.

You and I are probably the only ones wondering this haha.  I have a Ec-S on order, but my local shop doesn't have an ETA on the part   :(

I've been using LV for the time being.  Gotta tell you, so much better on the M haha

I am using EG-S on 6D, now I never change to normal focus screen. I have some F4 zoom, no problem but view finder is darker.
