Well on mine, Oly installed 1.3 and it totally knackered the autofocus. It's back with them - presumably they'll stick 1.4 on. Hopefully it'll get back to where it was under 1.2, which was perfectly acceptable autofocus.

If this is your success criteria then I am sorry to tell you that the S-AF under 1.4 is incomparable with that under 1.2. I can't comment on C-AF yet as I haven't got appropriate test criteria.

I dont know why we bother with these firmware updates! They seem to be so hit or miss!(although I had no problem with this 1.4)

1.4 went in fine for me too, took awhile longer than the 2 minutes suggested after it had downloaded.

I haven't as yet seen any reason to move from 1.2, am I missing anything?..

Serious request.

as I posted in the original 1.4 post in the E3 forum my personal view would be a resounding yes.

taking known 'difficulties' even within 1.2 - normal S-AF mode

my sigma 30/ 1.4 would miss focus frequently, but tell me it was in focus (only lens that did it) - both in good light and bad.

my 50/ 2 would miss then hunt in many situations, but never actually release the shutter without focus. in lower light and low contrast it would judder as little back and forward - the latter as many describe the 14-35/ 2's behaviour.

v1.3 had no noticable impact (either way) on these issues for me. It did however make a marked improvement in the deliniation between S and N sensitivity with N being increased and S decreased - bringing them more in line with the documented sizes in the manual. However C-AF now struggled to get it's initial lock for me, although once it got one it held it a bit better (subjective assesment)

then came v1.4 which some are already dubbing 'the phoenix firmware'. For me the instant xcheck of the above 2 lenses was a revelation - and further testing (with them) has so far 'blown me away.

here's one such test I devised as I started to push the (my) boundaries -

Whilst the resulting image may not look to tough at first glance

a. it's shot with the 30/1.4 at 1.4, normally my most difficult when things are pushed.
b. the subject is reflective
c. er there wasn't any light.......... 10 sec exposure at F1.4 iso 160. No doubt someone can convert that to an ev value. I really really couldn't see anything in the viewfinder to even frame on, so I mounted the camera on a tripod, shot to line up the target and AF point then switched off and on before taking the shot.

I even gave it s-t-d, so it could have 'grabbed' the washing basket in the upper area but it didn't, it saw something in the dead centre and grabbed that everytime.

5 shots taken after reset to infinity - 100% as this.

anecdotally others are shouting positives about the C-AF performance but I haven't had the opportunity to test it at all - yet.

Ah well, that's good news. I look forward to getting the thing back now, although the E-1's still great to use.
