Focusing

Hi

I’m pretty much sold on getting an M camera with a 35mm prime lens.

I like to take landscape images but have the versatility of a 35mm lens for street photography etc.

Rather than using the ‘patch’ for focusing on landscapes am I able to achieve perfect crisp focus at F8 from say 3m / 4m to infinity by turning the lens marker to the middle of the infinity symbol ?

This would be an advantage for me.

Thanks.

Adam.

But why would you not use the focusing patch? You paid a not inconsiderable amount of money to have one. Remember: zone focusing is the zone of acceptable UNsharpness which tapers off from the plane of focus. The image is only really sharp in the plane of focus.  It is mostly used for street photography, not for landscape or portrait, etc. 

On the M11 the zone of acceptable focus will be rather thin, maybe two stops down from the lens markings, depending on your level of tolerance of unsharpness and magnification throughout the imaging chain. The lens markings date from a time that one used film and for a print size of 10x15 cm.

If you want a deep zone of real sharp focus in a landscape, consider using focus stacking.

There are other programs, or you can do it manually in Photoshop.
