Mac,

An interesting article:

In a word, yes.

I wouldn't say all Sigma lenses are bad; there are clearly some pretty good ones.

However, I would say that using Pentax lenses gives:

a A guarantee that the lens will work as intended. This is not always true of Sigma lenses on non-Sigma bodies.

b A guarantee of at least a reasonable level of mechanical quality. Sigma lenses can be dire.

c The best lens coating available. Try pointing similar Pentax and Sigma lenses at the sun.

d Consistent colour rendition.

e Consistent operation - focussing rings turn the same way, etc.

f Truly wonderful quality when you buy good Pentax glass (which means all but the common consumer zooms) .

e That smug feeling you get when you know you haven't compromised on quality in order to save a little money.

Well, you got something right!

I have only one DA lens, the 12-24mm. I have no complaints with it, but to my eyes it is in no way better than the 31mm Ltd.

The whole business of digitally-enhanced lenses is over-hyped in my view, especially when applied to smaller sensors. Full-frame 35mm may be another matter, but that doesn't concern Pentax users.

The fact that DA lenses are generally pretty good is, I believe, because they are modern designs produced on powerful computers with sophisticated software, not a chap at a desk with a pencil and paper.

I've just realised that when Spirit of Will mentioned selliing a 31mm to "young" George, he was referring to me.

I can only say that in all other respects his descriptions have been totally accurate.

At this rate, the 77 Ltd is going to be the commonest lens around. But so what - it deserves to be.

Enjoy them, chaps.

G

The golden rule is: If in doubt, buy the 77.

Far better quality, and much faster, than the 80-320 zoom.

The Super A takes winder ME2, but not winder ME.

It also takes Motor Drive A, which is what you are thinking of. Faster, and scarcer.

G

The Super A is really a development of the ME Super, and offers the same plus full AE (program), shutter priority AE, and TTL flash. It uses the same accessories (eg winder, etc), plus a motor-drive.

It has a very simple and easy to use interface. I have had many Pentax bodies, and the Super A is my favourite.
