The advantage  of using the Sony a7 R111 with a 35mm Leica M lens and a Novoflex adaptor on the  poodlewalks is that I can photograph handheld in low light situations. The high ISO capability is something that I needed not all the tech  features as I use the camera in manual mode, as if it were a film camera.  It was still photography not video that I was interested in,  since video requires  expensive editing  software and it is a whole other world.  

The disadvantage of the Sony with a Lecia M lens is that I cannot do closeups of the objects that I see when walking along the beach or amongst the granite rocks.  I find this  frustrating as a lot of what I find  interesting along the littoral zone these walks  is in the detail. Photographing the detail   requires using a macro lens, which I do not have.  Up to now I use an old compact digital camera (the  Olympus XZ-1),  but I find the small sensor (10 megapixels) too limiting in terms of dynamic range,  tonality and  for post processing. 

So I have decided to use my old Sony NEX 7 camera that is sitting in a cupboard with a Voigtlander VM/E Close Focus Adapter, which   allows me to use  my Leica M lenses on both full frame & APS-C  Sony E Mount Cameras. I have just ordered the adaptor  from Mainline Photographics in Sydney.  It's a basic digital camera but this  combination provides me with the capability to do some handheld macro photography in soft light using a Leica M lens.

The Sony NEX-7 has limited low light capabilities--it can only go to 800 ISO without  noise appearing in the shadows, but this is better than using 400 ASA film. The  NEX-7 does  have a 24 megapixel sensor, and  this gives me a better dynamic range  than  I am able to get using the Olympus XZ-1. 

The latter does work okay with some subject matter: 

But the highlights blow out very quickly and the whites  often have a muddy greyish tonality.  So I need something better without outlaying a small fortune.
