    Two 50s on a G1, do you see a difference?

    I shot the same subject with two different 50s, a Minolta 50/1.4 & a Sears 50/2.0. I had too much light to shoot either wide open so both were shot @ f2.8, ISO 100 (lowest for my camera) & 1/4000s (fastest for my camera).

    1. Minolta 50/1.4 ($39 on eBay)





    2. Sears 50/2.0 ($11.50 on eBay)

    I love lens comparisons. The nerd inside me... I like the Minolta lens better thanks to its better (as in smoother) bokeh making the background a notch less distracting. How good the prices were not the other way round...

    i like the colors on the 2nd one more, but the first pic has better bokeh, overall i think i prefer the 2nd pic more. than again if you bought these to use wide open the story may change when you shoot them wide open
    NEX and some manual glass

    Minolta seems sharper & better bokeh.

    I agree with everyone so far that the Minolta's bokeh is better than that of the Sears. But it's certainly not 3.39 (39/11.5) times better.

    It's always like that for lenses: you never get twice the quality from a lens costing twice the price!

    I can't see much of a difference. Both are very good at this size. Perhaps at a pixel peeping level they might be different. Be interested to see a comparison with the 20/1.7. The more I use that lens the less I am interested in mounting anything else.

    Out of interest, what bayonet does the Minolta come in and what adapter do you use?

    I think the bokeh on the Minolta is much better for this type of shot.

    Yes, the Minolta is superior. The Sears (possibly a Ricoh?) is very good, but with one or two exceptions, all 50mm lenses are good. The additional performance by the Minolta and the wider aperture, particularly for portraiture, easily justify the price differential.

    That said, a cheap, throw away, lens is always useful, if there is a chance of damage, the smaller profile size and given the lesser weight, very much in keeping with the mobility profile of m4/3.

    Useful test, thanks!

    Perhaps when you have time, a faster aperture for both? A polarizing filter is almost as good as an ND for allowing wider aperture?

    The problem is about how to measure the quality and to asses that one is twice or just fifty percent more then the other one

    The Minolta is a MD mount on a RJ Camera adapter from this source:

    The Sears is a PK mount on an unknown adapter that was a gift.

    Thanks for the replys folks.

    I honestly did not see a difference but you folks obviously do. What a treat to have "too much light" after the native lenses being so damn slow.

    I have a 52mm neutral density filter that will fit the Sears but the Minolta is 49mm. I will check to see if I have a 49-52 adapter ring & try shooting both lenses wide open. I know I have a 52-58 but that is no help in this case.

    But, maybe it is 27.5$ better ????

    Mmm. Tempting, some of those 80s and 90s Minolta lenses were fantastic optics.

    Ron

    not as much as I saw between FD and OM both 50 1.8

    http://cjeastwd.blogspot.com/2009/06...d-fifties.html

    and definitely not as much as between the FD 1.8 and the 1.4 (even at 2.8)

    but you'll never get two lenses to look the same.

    This is of course the beauty of the digital cameras, you can compare lenses and get rid of more of the variables such as film stock variation and processing. Make sure you set the white balance manually or you'll see differences there too ... I've found that surprisingly noticeable just by changing the angle of view or the composition a tiny amount when checking out lenses.

    Thanks for that link pellicle, it was interesting indeed.

    The Minolta 50/1.4 has great reviews & that is why I bought it, the Sears 50/2.0 was cheap & that is why I bought it.

    I think there is a perception that if a lens is branded by a department store it is crap. Well, I am willing to take a chance for a few $ to find out. This is my third Sears lens & all cost me less than $25 including shipping (50/2.0, 135/2.8 & 80-200/4.0) & I do not regret purchasing any of them. Good fun.

    The Minolta certainly does seem a little sharper (more detailed) & does have better bokeh. Two good lenses and the Sears is certainly the bargain but considering you are getting a full stop faster lens with the Minolta, that too should be considered a bargain as that extra speed cost just $27.50. With new lenses of that focal lenght, you pay between $200 and $300 for that extra stop in speed.

    The first one...minolta...appears to be a bit nicer.
