It's been almost two years since Konica Minolta pulled out of the photo business and transferred its entire camera division to Sony, and well over a year since the first Sony DSLR (the DSLR-A100) was announced. Two years is a long time in the digital SLR market, but the three years Minolta (latterly Konica Minolta, now Sony) SLR users have been waiting for a high end model to replace the innovative Maxxum (Dynax) 7D must have felt like a lifetime. But, finally, it's here, and it looks very much like the mockup shown earlier in the year.
Like the A100, the new camera still wears its Konica Minolta heritage very much on its sleeve, and when you start to look a little more closely at the specification it's obvious that there's still an awful lot of Konica Minolta DNA in the A700. This is hardly surprising given that the circumstances behind its development.
And, just as the A100 was obviously based on - and designed to be a successor to - the KM 5D, the A700 follows on from the 7D, and - despite lots of Sony touches and an attractive new design - 7D users are likely to find using the new model reassuringly familiar.
But of course Sony doesn't only have existing system users in its cross hairs; the A700 is designed to go head to head with the latest 'prosumer' models from Nikon, Canon and Pentax. Whether the A700 offers enough to really put Sony on the DSLR map will be decided when we get to look properly at the image quality, but on specification, features and handling it certainly seems to have what it takes to play with the big boys.
Interestingly the one thing the A700 doesn't have is any form of live view; when we spoke to Sony about this the answer was simple; they believe that the compromises involved in current systems are satisfactory, and they won't implement live view until they can 'get it right'. Whether the lack of live view has any real relevance in a camera at this level remains to be seen; we doubt it.
The A700 shares many technologies with earlier Konica Minolta models (including, naturally, the lens mount), plus all those introduced in the A100 - though virtually all have been uprated or upgraded in one way or another (we've been told the A100 and A700 share virtually no components). From the sensor to the construction of the body to the GUI to the extensive feature set, this is a very different camera to the entry-level A100 (more of which later in this review). We'll start by looking at what's specifically new to this model:
What's new (highlights)
 |  |
12.2 megapixel APS-C 'Exmor' CMOS | Bionz Image Processor |
 |  |
| New AF Sensor The A700 features an 11 point focus system with a newly developed Center Double Cross AF sensor, claimed to offer 'the highest precision AD ever in a D-SLR'. The center focus point has two horizontal and two vertical sensors plus a new high precision (horizontal) sensor in the middle. This sensor has a baseline that is about twice as long as earlier AF sensors, enabling in theory, twice the focusing accuracy with lenses with a maximum aperture of F2.8 or larger. | |
 |  |
| Faster focusing Sony has also redesigned the focus mechanics, AF algorithm and microprocessor to offer faster AF. The target, apparently, was the fastest AF in any SLR, and to match Minolta's Maxxum 7 film SLR. | New High Speed shutter |
 |  |
| Anti-Blur Refinements to the Super SteadyShot CCD-shift stabilization system are now claimed to deliver up to 4 stops advantage. | Optical Pentaprism |
 |  |
Aluminum chassis/Magnesium body | Environmental Sealing |
 |  |
| X-Fine 3.0" LCD One of the first things you notice about the A700 is the stunning 3.0 screen. With 922,000 (well, 640 x 480 x RGB) pixels it has a resolution of 267ppi, plus high contrast and a wide viewing angle. A new high resolution GUI takes full advantage of the new screen. | Full 1080 HD output |
 |  |
| Wireless remote control The A700 includes a wireless remote control offering a fairly comprehensive set of controls (though all but the shutter release only work when the camera is attached to a TV). | Dual Storage Formats |
 |  |
| New kit lens Along with the A700 comes a new compact wide range bundle lens, the DT 16-105mm F3.5-5.6. The lens covers a range equivalent to 24 to 160mm and has internal focusing (though not zooming). | New Vertical Grip |
Other new / upgraded features of note:
- New advanced Dynamic Range optimizer functions (also supported in RAW)
- New software bundle with all-new raw converter
- Dedicated AF illuminator (red LED)
- New Creative Styles (expansion of color modes function on A100)
- 0.3 EV steps (or 0.5 EV if you prefer)
- ISO 3200-6400 expanded range
- Compressed Raw mode and X-Fine JPEG mode
- High ISO noise reduction control
- Grip sensor (optional trigger for eye control)
- RGB histograms
- New 'Quick Navi' control system
3 years on: A700 vs Konica Minolta Maxxum (Dynax) 7D
Before we look at the A700 and how it compares to Sony's first DSLR (the A100) and the rest of the market it's worth having a quick look at how it compares with the Konica Minolta 7D. Our first impression of the A700 was that in spirit (and very much in reality when you look closely) it is the successor to KM's first (and only) high-end digital SLR, introduced almost exactly 3 years ago at PMA 2004. it's obvious that the A700 contains a lot of Minolta DNA (there are elements of the D7D and the Maxxum/Dynax 7 film SLR in its design and control layout) and it's fair to say that - for users of Minolta's lens system - it can be considered a (long awaited) successor.
