next PZ Lens Test Report - Zeiss ZA T* 24mm f/2 SSM

That does not really make that much sense though, Klaus...



So on one side we have lens A, doing everything well (Zeiss 24mm f2). On the other side, we have 2 lenses, B and C, doing exactly the same things equally well (Canon 24mm f1.4 L USM II and Nikon AF-S 24mm f1.4).



Lens A gets a higher score. Why? It is not about that the f1.4 lenses, B and C, are more expensive, as there is another rating for that.



No, It is because lens B and C offer something lens A does not offer.



So... we have lens A, B and C doing more or less equally well at f2, f2.8, f4, f8 and so on. Distortion, sharpness, vignetting, bokeh, they are all close.

B and C do more or less equally well at f1.4, where lens A totally fails.



No, it is not right to rate a lens less, just because it offers f1.4 extra, where the other lens stops at f2. If two lenses perform equally, at the same settings, they should get the same rating. Price gets rated in "Price/Performance".



I do understand that then the rating will not specifically be about f1.4. And that at f1.4 one would hesitate to give it 4 stars. But rating a lens better when its f1.4 performance is just... non-existent makes little sense. And no, I do not know how to solve this in your rating system, right now. But it is food for thought.

I dont agree often with BC but this time he is right.(Logic wise, I didnt compare the test results and assume it is as BC says.)



Anyhow, we should not waste too much time and effort discussion star ratings here. In the end no sensible person is going to base a buying decision on them. You need f/1.4, you dont buy an f/2 lens. You shoot Canon /Nikon, you dont give a shit about this sony lens, because you wont carry around another camera incompatible to all your lenses just to shoot this wonder. In any event your Canon /Nikon 24mm gives fully usable results at f/1.4 so why would you worry about another lensmakers slower lens? You shoot sony, you are happy and dont care about canon, or Nikon as long as your sony lens is bright enough.
