Default Comments on Maxxum D7 spec



Well the spec is out and we are pleased. Of course the Canon 20D
now leads this segment of the market and it will probably take
Minolta a while to catch up ... if at all ... (the encouraging
note here is that the A1 went from 5 to 8 MP within months ...
but a different sensor size of course). The highs and lows a

The D7 (whether Maxxum or Dynax depending on where you live) has
a very strong spec. Using (we assume) the same Sony CCD sensor
as the Nikon D100/D70 and getting the same resolution and pixel
numbers with a 12 bit ADC. A fixed low pass filter is employed.

The high point wrt the sensor integration is that it will have a
slow sensitivity of ISO 100 and reach up to 3200.

The real bonus here is of course that the sensor is mounted on
the Anti-shake technology first deployed by Minolta on the A1 and
A2 SLR-like predecessors. This will give anti-shake margin of at
least 2 stops, 3 stops is claimed by K-M. So all my lenses will
benefit.

The system employs about all of the over achieving specifications
of the film Maxxum 7 with a few minor sacrifices (below).

Flash sync is a bit slow, with 1/160 (A-S off) and 1/125 with AS
on. This is a 1/3 stop margin between A-S on and off, so it
would seem in the studio that 1/125 with A-S on will result in
cleaner handheld studio shots than at 1/160 ...not accounting for
subject motion of course.

I'm disappointed, K-M should have had a quicker sync speed, at
least 1/200 and 1/300 from the Maxxum 9 would have been preferred.

The max shutter speed is 1/4000 which again is odd, as the Max 7
has a 1/8,000 shutter speed. In practical terms this is no real
problem.

The link above says "DOF" unknown. But previous releases
indicate that DOF preview is included. Let's hope that K-M have
not dropped this ball (the photos provided hide the position
where the DOF button is located).

Viewfinder: The spec says 95% and this has me perplexed. If
this is the Max 7 frame then with a 1.5X crop the viewfinder
should be something well in excess of 100%. I hope that K-M have
not crippled the VF as the spec here seems to indicate. (Could
be they just copied over the Max 7 spec without adjustment for
the sensor ... I hope so).

Flash covers all the bases from the built-in flash, wireless
flash and a PC sync terminal.

In a nutshell, a great first DSLR from K-M (Yeah I know it isn't
really the first one, but few people bought their expensive
kludge of a few years ago... the RD-175).

So, the two big questions remain:

WHEN? Maybe Photokina will reveal this...

HOW MUCH? as above...

The spec appears to have been rushed out to me and is possibly a
reaction to the release of the Pentax *ist DS announcemnt of a
couple days ago. K-M seem to continuously be in reaction mode.

Cheers,
Alan

There has been for some time. However, other such adapters are available at
better prices from other manufacturers -- the Minolta is most likely a OEM
unit anyway.

The 100 low limit means it's not the same sensor (most probably a variant
of it though). All cameras using the same architecture of the sensor has a
low limit of 200; the spec of the *ist DS is unknown WRT that however. It
may be a slightly revised Sony chip.

That, and the lack of a focus assist beam, clearly are cost-cutting
measures. The shutter disturbs me more than the focus assist beam, but with
HSS it's no biggie for me really.

Hey, don't badmouth my camera! It feels (as) bad as it is! ;-)

Rumours have been flying about a 15-17 sept announcement for weeks now.
It's no reaction.

It may be a revised v., may be the same (may be something else
entirely)... the ISO limits is a system integration issue ... how
you drive it and read it will have an effect on the sensitivity
limits.

Seems to show a focus assist beam xmiter below the blue logo.
(This may also be a pre-prod that is too close to the 7 and not
rep of the final).

Given the overall poor announcement quality and the poor state of
the website dedicated to the camera (lot's of place holder stuff,
very little meaningful detail) it seems reactionary. Their
marketing people are not being very sharp, IMO. It looks like
very poor prep prior to Photokina ... vice Pentax' first class
rollout of the *ist DS including a full review by Phil Askey on
dpreview.

As I understand it it's more of a register issue and thus directly related
to the sensor hardware. 3200 as max (the *ist D has it, the Nikons not) is
likely a design decision though; 3200 is too bad so they are not giving it
even as an option.

No, that is the final camera, and no, that's a self-timer led or maybe some
sort of IR remote release window. The D7D has AF illumination from the
built-in flash, or from an accessory flash.

Maybe they don't know themselves. The camera is finalized (some people have
review samples) but software might not be finalized -- sources (Minolta
officials!) says delivery by November. I certainly hope that's a
misunderstanding.
