Seems to be 12MP CMOS (same as D300)
5fps
ISO100-3200
CF & the unspeakable.

In cam IS w 4stops for normal lenses or wider and 2.5stops for teles (of unspecified FL).
New 11pt AF w 1 cross sensor
1400Euros body only.
1500 Euros kit
2100 Euros w zeiss 16-80 and other accessories (as yet unidentified).

Opinions?

So is this an admission that sensor-based IS works better on shorter focal lengths?

Currently, it sure works better at 10mm I guess than a lens based IS system...

;-)

Cheers,

Curious where did you get the price?

And is that VAT inclusive? lol

Clint is on holiday! Soon to return! ;-)
 
Or doesn't work as well on tele's as has always been assumed. Pretty much a me-too offering as far as I can tell. I think the winner this round has to be Nikon.

Well, yeah, but I was trying to state it in the positive, not negative sense. :-)

As we already knew.

However 4 stops is a lot - for nothing - on any lens you want... inc exotics...

2.5 stops is pretty good - for nothing - on any tele you want... inc 3rd party...

I think we need a graph showing IS effectiveness vs focal length. That would clear things up nicely. Let's have it.

No, it was the poster's own comment, nothing to do with Sony.

In my experience of the Sony Alpha 100, I can shoot at about 1/20sec at 135mm or 1/10sec at 50mm. The effectiveness gets less at very close distance.

My guestimate for the Sony Alpha 100's effectiveness is thus:
  • 3.5stops for 100 to 500mm AND at a good distance
  • 2stops for 50mm or shorter OR at a very close distance

It offers features that compete with the Canon 40D, and it is priced accordingly.

Stats comparison between A700 vs 40D:
  • 12MP (5.5 µm) vs. 10MP (5.7 µm pixel pitch)
  • ISO 6400 vs. ISO 3200
  • 640x480px LCD vs. 320x240px LCD
  • anti-shake vs. liveview
  • 0.9x vf @ 1.5x crop vs. 0.95x vf @ 1.6x crop
  • 5fps (unlimited) vs. 6.5fps (75 frames)
  • full weathersealing vs. partial weathersealing
  • 11 AF points incl double cross-hair vs. 9 cross-hair AF points

I agree with the views so far.

A700 seems ok. I love the in-cam IS, but it's not as important to me as speed and AF.

Nikon won this round already.

Looking forward to Sony's 'flagship' if it turns out to be real.

I did also note that apparently Sony are now aiming to be a clear 3rd in the DSLR market! That's a world away from being 2nd considering the top two. Seems even Sony have decided that the DSLR business might be harder than they first thought.

The most interesting thing for me is Sony's apparent partnership with Tamron. This 8could* be good for all users as Tamron are surely getting a good boost from this relationship.

On the other hand, Sony may now have some influence over what Tamron produces. Meaning they will prioritise lenses that Sony wants (needs for the line-up) at the expense of lenses that might have a wider appeal - or at the expense of more specialised lenses that Sony don't think their user base will want.

That could go on for years effectively removing Tamron as a lens innovator for the rest of us.

And as for Sony's Tamron lenses, why on earth would someone buy the Sony version of a Tamron lens when they will surely have to pay extra for the priviledge? Surely, you'd have to be ignorant or snobbish?

Is this not tantamount to Sony just saying to customers: "Sorry, no new lenses from us. But there are a couple of good 3rd party suppliers you can use!"

Oh well.

Not a bad cam. Better than 40D on paper imho due to D300 sensor and in-cam IS. But not up to the v impressive (and more expensive) D300.

A700 seems a little pricey considering the overall Sony package (inc lenses, etc).

Was really hoping (dreaming - as I knew it was just that - a dream) that Sony might release this at a v special price seeing as they needed to become #2 in the DSLR market in next to no time. Should have known that they'd just change the target rather than release anything that wasn't carrying a 'Sony premium'.

Eagerly awaiting benchmarks on all the above cams.

Maybe a little disappointed in the new A700 due to lack of important lenses (esp from Zeiss), speed, lack of live-view, no mega AF, and as already mentioned - the price.

Canon's center sensor is a cross/X type. A first for them on digital. It is my understanding that KM had one or more of these in it's last high end film SLR.

No significant difference in stops improvement between 70mm and 300mm, 2-4 stops stabilization on an a100.
