I find it very disappointing that the test doesn't take different focal-lengths in to account. Looking at 100% crops is very misleading when the focal-lengths vary from 26mm to 33mm. Naturally the...

APS-C is the leading system-camera sensor. Most units sold, and fastest developement. APS-C leads the curve when it comes to sensor technology, it usually takes a couple of years for said...

DPreview already covered this: "Sigma's choice of F1.8 as maximum aperture isn't a coincidence; it means that the lens will offer the same control over depth of field as an F2.8 zoom does on full...

Well, shutter-speeds won't be 1 1/3 faster for the same SNR, tonal-range or dynamic range. The bigger sensor will gather more light for any given f-stop, meaning that you can up the ISO and get...

One which is from 1998, the other from 1993. Look at the pricing of Canons refreshes to get an idea how much modern versions would cost. New lenses cost more, as they are better and they are not...

And you take pictures looking through the viewfinder, not at the top of the camera. And yet, you're not complaining about the position of the shutter-button. The record button is next to the...

There already was one, since 2010: http://www.dpreview.com/products/compare/side-by-side?products=nikon_d7000&products=pentax_k5iis

There are plenty of alternatives that can match the MBP Retina for weight and gamut. Even pixel pitch, but not in resolution. If you want the most lightweight alternative, that would mean a 13"...

And the same could be said about almost any comparison between any gear within the same class, be it lenses, cameras or flashes. Everything comes down to nuances, and all gear is capable of...

Do you have that comparison in a larger size? It's very hard to tell any difference when looking at such small pictures.
-
Hence you didn't understand what I was saying.
-
Yes, it does. The operative word being *commonly*.
-
This has nothing to do with the question at hand: You've shown no basis for why a lens that is visibly better at a CoC would be worse at another. The Zeiss paper you yourself linked to contradicts...
-
If the radius is large enough. But for that to be relevant to this discussion, the radius of the test scenario used by Lenstip would need to be so large as to hide differences. This of course isn't...
-
If you interpreted the non-homogenous inner circles as affecting the smoothes of bokeh, then no, you didn't interpret them correctly. Outlining is what governs that which is usually considered the...
-
Sure they do. Acroding to the Zeiss paper you linked to earlier, the amount of correction only affects the starting point of the thin-ring emphasis, not the progession. If you compare the circle of...
-
If you're asking if the Sigma 35mm will have as good a bokeh as the 135mm F/2, then the answer will be no. No 35mm will. However what you can see from those crops is that there is very little...
-
In a vacum, yes, slightly. Beside a better lens, without a doubt. And my main point was the second one, that the amount of correction only affects the starting point of the thin-ring emphasis, not...
-
I disagree. The difference between a overcorrected lens and a better corrected lens is visible in all regions of the OOF rendering given a problematic backgrond, not only when not far out of focus....
