Focussing with the LCD and/or EVF

I see a lot of comments about focussing difficulties with the LCD and especially the EVF. I was a TV cameraman for a while as well as a sound mixer so here's my take.

Practice, practice, practice.TV studio cameras have no focussing aids at all, just a small monitor perched on top of the camera and focus doesn't seem to be a problem.

I don't seem to have focussing problems myself but prior experience has helped.

So practice. It works.

What f stop do they shot at in studio?

practice is always a good idea- if you want to improve at a given task...

 

but focus aids would also be good- if they worked.. I just noticed in the M240 user manual- in the section about focus peaking - there is a highly misleading image of the LCD screen showing objects in focus framed in red. I challenge any Leica M user to replicate that image or anything close to it: it is impossible to see such red frames on the lcd without magnification- and probably even with magnification. Especially so with a wide aperture- which ironically is the situation where critical focus is most important- and an aid to achieving it most desirable...

 

so I guess your advice is doubly good: practice or be damned.

Historically, the main complaint about video cameras has been that they show far too much depth of field. If you've ever watched a sporting event on TV, especially in high definition (e.g. European or American football), you've seen this. Everything is in focus, indiscriminately. There's even an argument that this has changed how people appreciate/respond to moving images.

 

In other words, video cameras don't have the "film look". This is the principal reason why DSLR video became of interest. DSLRs overcame the "problem" with video depth of field, although there are now adapters for video cameras that can kind of correct this "problem".

 

If one is a fan of Citizen Kane, a film noted for unusually deep apparent depth of field, one might have a less black and white view of the issue.

 

Regardless, the bottom line is that M 240 focusing and video camera focusing are not the same thing. The former is a lot more like focusing a film cine camera, which a video camera is most decidedly not. And yes, it's about sensor size.

You seem to refer to an illustration which I personally think is clearly recognizable as a schematic drawing. However, it might have been wiser to include an actual shot of the screen.

it is not a schematic- it is a drawing of how the red edge focus aid supposedly works. As such it is completely misleading. I don't think they could have used a picture of the actual screen as if they had: they would have realised that what they were suggesting the camera could do: is actually impossible. :eek: Perhaps they did realise this: and hence the drawing.

In my experience the focus peaking does exactly what that drawing shows on the LCD without magnification although it is easier to see with the 5x or 10x magnification. The red lines are easier to see if you have the camera set to BW film so tht the preview is BW. If you have Focus Aid set to manual you must push the front button to activate it of course.

I think it is somewhat dependant on the light levels and subject though. I wouldn't take the drawing as a literal example since it shows a person shape if you like. It works with edge contrast.

 

My view is that it is a possible aid and for some applications (long teles, macro etc) liveview and focus peaking are the only option. Experimenting with my M lenses wide open and otherwise, I find it gives an acceptable range perhaps (of focus ring movement) but nothing like the precision of the RF for critical applications.

I know that I've got an (Oly) EVF squirreled away somewhere since my camera was unavaillable for 3 months but darned if I can find it again yet to experiment more :o
