35mm full frame lenses for Sony E-mount

introduction

  • one of the reasons for shooting full frame instead of the more compact Micro Four Thirds system is to gain better background blurring and subject isolation with wide angle lenses which is more difficult to achieve on cropped sensor cameras without resorting to f/0.9 lenses
  • in this regard, the Sony 35mm f/2.8 lens does not make very good sense, particularly at the price - you may as well use a much more affordable and jacket pocketable system such as an Olympus OM-D with 17mm f/1.8 lens and shoot this at f/4 to gain the street photographer's desired DOF (they would shoot f/8 on full frame with a 35mm lens) - but if you don't want to own two systems then the f/2.8 lens may be attractive as a compact albeit over-priced option
  • the Sigma 35mm f/1.4 ART lens is one of the best 35mm lenses ever made and is highly regarded but it is large and heavy and not great to carry around on streets all day - it is more appropriate for wedding photographers and fashion photographers who appreciate its shallower DOF, sharpness and bokeh and don't mind the weight BUT it seems not everyone loves the bokeh - see http://www.diyphotography.net/sigma-art-lenses-great-glass-shitty-bokeh/
  • another alternative if you are hunting bokeh is the, bigger, heavier, weathersealed Canon EF 35mm f/1.4L II although this is $AU2650!
  • a compact alternative is the $AU800 Canon EF 35mm f/2.0 IS but the IS would only work on Sony with the Metabones adapter
  • an even more compact options is the $AU199 Canon EF 40mm f/2.8 STM pancake lens

bokeh reasonably nice edges but mod. onion ring and cat's eye at edges “excellent”, but some onion ring cat's eye shape as vignetting, severe onion rings, busy
long. CA some
coma need to stop down to at least f/4 to reduce
comments can use on Canon dSLRs too, best bang for bucks but heavy heavy, expensive almost pocketable on an a7II, a nice street lens, but may as well shoot with Micro Four Thirds system
other like most recent Sony lenses, focuses stopped down at your selected aperture. This means that autofocus performance steadily drops as you stop down, since smaller apertures mean less light, and more depth-of-field (less phase difference) for the autofocus system to work with. By F9, phase-detect fails altogether, and you'll experience significant hunting in AF-C. faster AF than the Sony 35mm
