This function works great to check composition, expression, lighting, etc.

Thanks for the tip David.

Will try once my S2 will come back from Leica Portugal,…[Read more]

I'm curious what drew your attention to this post? I tried to make it attention getting but perhaps I could do better?

So now tell us your 35mm story please

Since I just bought a S2 ( I know, I know, not two years…[Read more]

Hahah yes the M is lovely if what you shoot can be captured by the manual focus or pre set focus.

I have access to an S2 at a no brainer price, not as no brainer as the D800E and that would certainly be a back up given I use Pentax lenses on the Nikon now. I was quite shocked at the lack of DR.

The Leaf and Phase seem to recover…[Read more]

But the big attraction to the S system is the S glass and I think that in the not too distance future Leica will add a…

I don't understand how the D800 has more dynamic range ?

There is about 20% more detail on the S file, which when blowing big is great. But the highlights in the sky are all but gone in about 50% of the sky on the S. the Nikon…

This is a brilliant post and thanks to who started it. The findings have pretty much made me decide to go S2 as soon a s I can dump Nikon gear.

Have a large number of Pentax 67 lenses only missing the 200mm. F4

Question I have is in the field is this camera usable at ISO 320-640 ?

Any update images since the original post…[Read more]

RVB thanks for the offer I would love to get the files will try from the link enclosed.

I think I am hearing what I need to here and yes adaptors are expensive but if they work then it's better than missing the shot and as you say I have an inexpensive entry into the S world.

Thanks for all the support I am now wondering what the…[Read more]

Actually, it has nothing to do with the viewfinder Doug. It is the back tethered to a computer using Phocus software. This is why…[Read more]
