As I mentioned in the previous post; if your shooting full frame 35mm then lens around 85mm are the traditional focal length for portraits, but one can go longer or wider.
For myself in general when in the studio if shooting 35mm full Frame it tends for me to be a 105mm portrait lens or a telephoto zoom, depending on how I am working that day. As I mentioned I do not currently a traditional portrait lens.
For my environmental portraits I often go wide, usually a 35mm lens but occasionally 24mm or 50mm.
Getting a more traditional focal length for my Leica has been on my purchase list for a few years now.
Its not been high on my list as a) Leica glass is expensive and b) for more traditional portrait focal lengths I am generally shooting with an SLR.
This month Leica have released a new 90mm portrait lens, the Leica Summilux-M 90 f/1.5 ASPH. As you can see, at 90mm and f/1.5 giving it an object lens of 60mm diameter as well as it having an aspherical lens element means that it will be good (well amazing) and also with this amount of technology its going to be expensive.
I have to admit that I even I was a little shocked at the price so I’ll be going back to look at second hand 75mm and 90mm Leica portrait lens but its good to see Leica pushing the envelope in what is possible in lens design.
