Jeffrey Friedl's most recent post was about a French photographer and author, Stéphane Barbery, who borrowed Jeffrey's camera for a while because he wanted to enjoy 'a thin depth of field with my Nikkor 85mm f/1.4 that his current camera can't match.' That's even less of depth-of-field, or more selective sharpness, than f/2.8, especially with Jeffrey's full-frame camera! By halving the aperture number, the selectivity of sharpness is doubled--as a figure of speech.
Are those lenses more affordable in Japan, where he lives, or is he just fanatic about maximum light and miminum depth-of-field? Anyway, it makes me jealous--not because of the price or the weight (both must be tremendous), but because of the photographic possibilities it gives.
What also makes me jealous is how this Stéphane Barbery has a very different sense of photographic beauty. Friedl discusses a 'throw-away test shot' that Barbery made and that he finds beautiful. So did I. Have a look here; it also gives links to Barbery's web site--worht a look too!
