M10 monochrom - filters?

I recently shot about 200 images in Joshua Tree Nat'l Park, about half of which were with my 28mm fitted with a #25 red filter and the rest with my 50mm fitted with an orange filter. I had no discernable sharpness problems.

Never needed one and don’t usually see them.  Technique satisfies; same with RF viewing and focusing.  Practice.

Also depending on resolution and expectations. And physical ability too.

And just to complete this, today, my Visoflex EVF arrived and from what I did so far, I can strongly recommend this when using filters, especially the dark red. No unsharp pics anymore. Problem solved.

I've just done a few more tests myself and it seems that I was over-compensating in my earlier trials with the Leitz Red filter. Near-focussing just a fraction - literally turning the focus-ring 0.5mm - sharpened up the image for a subject placed at infinity when shot at f8. Different amount of focus-adjustment needed for wider apertures. Different amount of focus-adjustment needed for closer-up subject matter...etc..etc...etc...

The amount of adjustment varies with both distance and aperture; there is not one hypothetical 'index mark' which can be used as a catch-all.

As I don't have the option of Live-View on either of my M bodies I guess I'll skip using the Red. It's been an education!

I have noticed this too on my M10M. There is significant focus shift when using B+W yellow, orange and red filters. Plainly obvious. I was surprised to see that much shift, even with the yellow. The RF on my M10M is dead-on with a UV or nothing. But with the filters normally used for black and white, the EVF is the only way to achieve accurate focus.

Year old thread, but most all here don’t experience significant shift using yellow (or even orange) filter.  Red is different.  I have no issue using yellow on my M9 Monochrom.

And with the lens used - with an APO lens there will be no shift, with a Summilux 50 asph very little, for instance.

AFAIK, there'll be no focus shift against 8-elements and Rigid while applied Red/Yellow/Orange filters either on the M10-M or M10-P according to recent field test result.

No problem at all form my side when suing yellow filter. I’m planning to get an orange one in the near future so hopefully it’s fine while using RF as well

Sorry for the delay, you are right with the 50 Summilux, which also delivers the best overall results so far. Will check with the APO-Summicron 75 later.
