A quick test of the DA* 55/1.4 and the DFA* 50/1.4 - the first two are full frame no PP, the next two are crops of the first two with adjustments to highlights/shadows, exposure + CA adjustment - no sharpening. Focus is one the word "one" on the face-on pound coin. Click for larger versions on Flickr....
1. DFA* 50/1.4 @ f1.4:
2. DA* 55/1.4 @ f1.4:
3. DFA* 50/1.4 @ f1.4 - cropped and PP:
4. DA* 55/1.4 @ f1.4 - cropped and PP:
No particular reason for this test apart from showing the basic differences between these two Star series lenses without the usual processing we're used to seeing. The DA* is of course designed for APS-C, but this test doesn't aim to show edge to edge sharpness, just the quality wide open.
I'd say that the DFA*50/1.4 is sharper and more contrasty wide open, but the DA*55/1.4 is no slouch - it certainly doesn't need to be stopped down to f8 to compete (IMO)
These are the shots in a mini Flickr album if anyone wants to look closer...

Poor weather and other commitments mean I haven't had much chance to use mine as yet, but from the few shots I have taken it does look as though it has some lovely characteristics:
1. @ f1.4 (minimal PP (Default LR pluse shadow/highlight adjustments)
2. @ f1.4 (minimal PP (Default LR pluse shadow/highlight adjustments)
3. Same as shot above but with some extra clarity and sharpening

It'll be interesting to see what happens to the Second Hand market in "fast fifties" once the D-FA*50/1.4 touches down - over the past couple of years in the UK the K, M, F and FA 50/1.4's seem to have dropped in price, and the DA*55/1.4's have even been seen for around the £350 mark :eek: . I suspect the K and A 50/1.2's might drop a little as users divest their duplicates (not everyone is like us and keeps at least one copy of everything ;) ) - could be the right time for some bargains to be had :D
