Hello to all...
Thank you for the information Mr Laing, I will be waiting this analysis...
I expressed that of the analysis of Sony 50mm f/1.4 in view that I have at the moment a Minolta AF 50mm f/1.4 (original version, 1985-1986) and it works "well" in A100.
I have listened very good references of this lens, but to part of this Minolta 50mm f/1.4, also exists the 50mm f/1.7 (original version of the same year) and two "new" versions of these lenses denominated RS, in total they are 4 lenses that apparently alone they differ as for the diameter, 49mm for the original versions and 55mm for RS. To this it would be necessary to add the Minolta 50mm f/2.8 Macro with relationship 1:1 (with several versions) and Minolta AF 50mm f/3.5 Macro with relationship 1:2.
Therefore we are speaking of more than 6 models of lenses Minolta 50mm and two reissue Sony (similar to Minolta f/1.4 RS and to the Macro f/2.8 D version) and here I think about the dilemma.
I have not had good experience with my Minolta AF 50mm f/1.4, in the occasions that I have used it I consider that I have been presented a phenomenon of back focus and lack of sharpen when making an amplification in PS, although apparently, the first thing that I indicated, is caused by the camera, Sony AF 100mm f/2.8 Macro works very well without this problem (and with an AF quicker), but they informed me that apparently some lenses Minolta could have some defect that caused this problem, for what I have thought about to substitute it for other 50mm but in this case a Sony 50mm and although I already have a Macro (Sony 100mm) the price difference as for Sony f/1.4 and f/2.8 Macro it is of hardly $150 (to the change of the Venezuelan currency).
Would it be worthwhile 2 steps more than diaphragm with Sony f/1.4 that to take advantage of the focal same distance but in a lens Macro?
How will the image quality it will be in both for portrait?
Will the quality of f/1.4 of Sony have improved with relationship to the previous versions Minolta in view that this built one thought of a digital reflex?
Excuse so much to write and my English, but these are my doubts...
