Hi! SP> Reading tests more and more in more places, I found them to be just SP> unreliable. For instance: SP> - according to Folorfoto MZ-S has one of the slowest AF among current SLR SP> bodies (just slightly faster than Dynax 404 and 505, and much slower than SP> MZ-3 and N*** F65...), the same test in FotoMagazine, and MZ-S has one of SP> the fastest AF (beting easily even F100, Dynax 7 and EOS3...) SP> - in FotoMagazin test MZ-S has quite poor matrix metering, in ColorFoto it SP> just got better - better than F100 or EOS-30 (which were far better in SP> former magazine tests...) SP> - standard zooms - according to ColorFoto FA 28-80/3.5-5.6 is far better SP> than FA 28-70/4 and what's more than FA* 28-70/2.8!!! SP> - long zooms - according to photodo, F 70-210/4-5.6 is undoubtly better SP> (3.4) than FA* 80-200/2.8... SP> ... and so on, and so on. SP> I am just tired of this "mish-mash". The best way is to make tests yourself SP> - if the lens or body proves to be better for you rather than for testmen SP> than just get it and be happy!
It has occurred to me reading the above, that the published lens or other equipment tests are much close to statistics than to anything else. Statistics is good with very big number of samples. Now, if you take ten or even twenty lenses of some kind and test them in some manner, you get twenty different samples of statistics for that lens. Given the number of variables involved, it literally means zilch - something like: There is a company called Pentax that happens to produce some zooms, one of which apparently in my hands used in such an such manner gives such and such results. Very well, who really cares? I mean, do you really shoot test subjects only? Even for M Reichmann test - I doubt any of you would travel all the way to Toronto in order to use your stuff on his (favorite) location. See, I've bought this Soligor 70-222/3.5 C/D zoom. Some months later I've been advised to shoot with this lens a newspaper attached to the wall. So I've discovered that on wide end it has some kind of distortion - the trees on the boundary of the frame are a little round - I don't know the name of that distortion. It really means very little, because I am yet to find a subject that would severely suffer from such distortion. Again, this is my shooting, yours may be different. I see only one thing that can be useful for tests - you read about the lens, you probably learn, you might get some conclusion if you happen to trust the tester, or if your needs are similar to those of the tester. Otherwise, tests are just a good technical reading, no more. Sometimes it may even give you a reason to chuckle ("FA 28-80/3.5-5.6 is far better than FA* 28-70/2.8!!!"), which is definitely a good thing. I totally agree with Sylwester here. --- Boris Liberman www.geocities.com/dunno57 www.photosig.com/viewuser.php?id=38625
