No doubt the best build quality of the trio, but probably the weakest optically:

you'd want to fix the model name in the final evaluation... it's still "24" <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />

Thanks Markus! You've confirmed what the (precious few) other reviews of this lens are suggesting:

Oops, sorry. Fixed, thanks for the hint.

It would be interesting, how the trio (20/1.8, 24/1.8, 28/1.8) performs on APS-C. For the 20/1.8 there is a test on Canon, which could indicate a better performance ( http://www.opticallimits.com/canon-eos/2...ew?start=1 ). As an alternative to additional tests on APS-C, one could include MTF measurements at the corresponding APS-C borders in other full frame reviews in the future. Unfortunately, there are still systems with neither fast prime wide angles nor full frame cameras like Pentax.

Most of the lenses reviewed on the D3x will also be tested on the D7000. This includes the 3 Sigma primes.
