What can it do that a Nikon F5 or F6 cannot do?


Sorry for my delayed answer. Here I'll only give a few hints; details (including images) will be published on artaphot.

I'll compare the Minolta Dynax 9 (less sophisticated than the Dynax 7, but a professional SLR) with the Nikon F5. Basically the two cameras have a similar performance:
* P-A-S-M mode
* EV range: 0-20 (Dynax 9 and F5, matrix metering)
* Shutter 30s - 1/12'000 (Dynax 9) vs 30s - 1/8'000 (F5)
* flash sync 1/300 (D9) vs 1/250 (F5); high speed sync 1/12000 (D9) and 1/8000 (F5)
* Flash metering: 14 segment (Dynax 9) vs 5 segment (F5)
* frame rate 5.5 fps (D9) vs 8 fps (F5)
* AF speed (with 1.4/50mm, S AF mode): similar for both cameras. AF C mode: probably better on F5 (five vs three AF sensors)
* AF range (EV): -1 - 18 (Dynax 9), -1 - 19 (F5)
* Body material: stainless steel (Dynax 9), aluminium (F5)

There are a few substantial differences:
* integrated viewfinder (Dynax 9) vs changeable viewfinder (F5)
* changeable battery pack / grip (D9) vs integrated battery / grip (F5)
* built-in flash (D9) vs no flash (F5)

The main differencs between the Minolta Dynax 7 / 9 and the Nikon F5 / F6 is the user interface (ergonomics). Simply said, the Minoltas are miles ahead for two reasons: 1) much better vertical grip, and 2) direct access to a vast number of functions (separate dials for all these function, no awkward "open the cover - press the button - turn the wheel" sequences, just a simple and direct straight access).

Here's the details wher the Dynax 7 and Dynax 9 are better:
* P-S-A-M mode directly accessible. Selected mode visible also when camera is off (even at night due to fluorescent letter!!)
* shutter speed / aperture control: front wheel is angled at about 50° and therefore much easier to use than the wheel of the F5 / F6. Not the cheapest solution to build, worth the trouble!
* Frame rate: Direct access for "Single" and "Continuos" (as in F5), but in addition also direct access for Bracketing (S and L) and multiple exposure (ME)
* AEL / AF buttons have a reasonable size (much too small on F5, improved on F6)
* AEL button induces "slow sync flash" when a flash is used. Extremely useful for reportage / marriages / concerts, especiially with the built-in flash of both the D7 and the D9 !!
* large double wheel for A) exposure compensation and B) flash exposure control (direct access!). Extremely useful.
* built in flash (guide number 12, angle sufficient for 24mm wide lens): Extremely useful for slide and color negative film - remember these were the times when ISO 400 was "high sensitivity". Gives well balanced color slides when used in artificial light with 5500K films.
* much better ergonomics in portrait format: A) reasonably shaped grip (the F5 grip is ridiculous) and B) both control wheels doubled for portrait format (no wheels on F5 grip!!) and C) AEL and EF buttons doubled (no such buttons on F5 grip)
* eye start for AF (AF activates as soon as you A) touch the main grip and B) look through the viefinder). Can be turned off - yes! - without going into menues!
* direct control (not via menu) of flash modes (normal - rear sync - red eye reduction - wireless)
* Camera directly controls the wireless flash mode (no "master flash" needed)
* much easier mirror lock up mode: 2s self timer is combined with MLU (retains AE mode which makes it much easier to use)

In addition - and here comes the "most sophisticated SLR" - the Dynax 7 has a few gimmicks that usually can be found only on DSLRs:

* large rear LCD screen
* nine AF sensors
* menu in different languages
* data back integrated in the camera
* memory module to save the data of about 1000 images (early EXIF system)
* 30 custom functions directly accessible via screen (no user manual needed!)
* sophisticated thumb control wheel on rear side (much more functions than on F5)
* Nice AF/MF button (no need to fiddle with the murky small selector on the F5), in addition to the traditional AF selector of course
* selector for the AF area (large [9 sensors], variable [any of the nine sensors quickly selectable], lock [one of the nine sensors permanently selected]


All that said - the mirrox box of the F5 is vastly superior to the mirror box of the Minolta Dynax 9: faster, less noise, and less vibration. And it was very well protected by Nikons patents, thus blocking the pathway for Minolt / Sony to create an equally fast "Minolta Dynax 9D" (aka Sony Alpha 900). To circumvent this, Sony had to give up the mirror. The rest is history ...

A few days ago I found a rather early "Miranda T" SLR, shown below. According to 1992 McKeowns it's the second only of the numerous Miranda SLR models, produced in the 1950s. The first version of the "Miranda T" (which distinguishes itself from the second model only by its "Miranda Camera Co" instead of the original "Orion Camera") was the first Japanese SLR with exchangeable prism finder - certainly a kind of milestone for Japanese camera history.



The shutter is a bit limited, going only from 1/30s to 1/500s. The camera is quite well made - maybe not as refined as a contemporary (early) Pentax, but certainly not much inferior. The viewfinder is surprisingly bright for a SLR from the 1950s (in daylight certainly much brighter than the rather dim EVFs we got used to during the last few years).

An interesting find indeed!

Good suggestion - however the shutter has some bugs. The 1/30 actually acts as "T", the 1/60 and 1/125mm seem to be working, the 1/500 opens only partly, and probably the 1/250 is inaccurate. Pretty limiting - would result in approximatly f11 in daylight. Which means I could use any camera ... nothing specific or particular to be found in the images, I guess ...

Therefore I'd better go out with my late war Contax III which has been painstakingly restored by Henry Scherer (zeisscamera.com). Or with the rare "Linhof 220" 6x7 rangfinder camera ... which is really a strange camera, though probably an excellent one. Everything seems in fully working order, but I've never actually been using it. The fancy grip below the camera reminds of contemporary 16mm film cameras of course, but the whole setup feels rather shaky when shooting. It probably was developed as a replacement for the large fromat press cameras (such as the Graflex), but too late to make an impact. The Nikon F was the way to go.



The Contax III certainly isn't a small camera (comparable in size to a good SLR), but the Linhof 220 rangefinder is huge.

A heavy sucker but an absolute joy to use... especially with some nice Zeiss and Yashica glass such as the 21/3.5!!

A little late with this one.





Fairly pristine late run chrome F2.
Seller said he bought it for using in his high school photo club,
then gave up the whole idea after a matter of weeks.
He said he had put 5 or 6 rolls of b&w film through it,
and then it sat in storage for 43 years.




The pre-AI "K" 50mm f-2 is a nice lens I like it a lot.




It also came with a 200mm f-4 "Q.C." that I have yet to use.
Compared to my black "beater" F2, there's a huge difference.
Film advance is almost equal in smoothness to my F3.
My black F2 goes "Flap" (mirror up) and "clack" (shutter trip)
The new to me chrome version is more of "ping and ting" affair, and a bit quieter.
The only mark I can find on it is a tiny scratch in the chrome of the top plate at the front,
and it's barely discernible...

I am quite impressed with this!
The factory leather strap is still quite pliable after all this time.

What a beautiful XE!! Looks like new indeed!

And the Minolta 600si classic is a milestone in the Minolta Dynax lineage. After all these "computerized" user interfaces the "classic" user interface of the 600si was the beginning of a new aera. The Dynax 9 (and later the Dynax 7D and the Sony A900 which in reality was the "Dynax 9D") would become the culmination and terminus for those expensive and labor-intensive user interafces.

Thanks Steve. Not new but has had very little use during it's life. I replaced the light seals and the meter is accurate.
I have a chrome version too in pretty much the same condition.

Probably better than the digital back SB-90S for the Minolta 9000 (1986):

0.38 MP on a 2/3 inch CCD sensor! But hey, 1986 !!

A few days ago this little black Minolta AF-C caught my attention (she was in the waste bin of our local photo store awaiting destruction) - so I saved her Wink. Back in its days (1982) the AF-C was pretty expensive - around 500 DM or half the price of a Minolta X-700 SLR including 1.7/50mm normal lens!

While the AF-C feels pretty cheap (it was made mainly from lightweight plastics), technologically it was top level: A miniaturized AF module, AF-Lock, program mode from 1/8s @ f2.8 to 1/500s @ f16, LEDs in the viewfinder, and - last but not least - a high quality 2.8/35mm [6/6] lens with rear focus (!).

Today, at the same shop, another AF-C was in the waste - this time a white one with its original flash. What a funny coincindence ... Wink

Even more impressive, a digital back from the 1986! It's a pity the page does not show test shots taken with it.

Here's another one - a quite common Minolta X-500 with the no-so-common MD 2/135mm lens:



I always felt the X-500 is more "professional" than the X-700, even though the X-700 officially was the higher rated camera, of course. The X-500 has no program mode (just A mode and M mode) which feels "cleaner", and its manual mode metering is better engineered (LED show both the recommended / measured shutter time and the time manually chosen on the camera). In addition the X-700 doesn't allow slow flash sync when using dedicated (TTL) flashes, even in manual mode the camera insists to have 1/60 s ... With the X-500 you can use slow sync combined with TTL measuring, at least in manual mode. This feature is quite important when shooting events, concerts and weddings.

Here are the X-500 (with MD 1.2/50mm) and the X-700 (with MD 2/135mm) together:



The viewfinder of these SLR is among the best (=brightest and largest) I know - by far larger than the OVF of the Nikon F5 or the Nikon D3, for instance. It's a real pity Minolta didn't put all that engineering of the X-700 into a rugged metal body, combining it with the metal shutter of the XD-7 (which went up to 1/2300s even though it was officially only 1/1000) and selling it as X-900 ...!!

There are similar (un-substantiated) claims made for the shutter of the Nikon F-3, which I take with a healthy pinch of salt over the left shoulder.
I've been un-able to force my version to 1/4000th sec in "A" mode, no matter how hard I try. Wink
I still prefer the viewfinder of the F-2 over all others. It is the only finder that I am able to focus off the ground glass with, despite it's slight dimness.
The "E" screen in the F-3 comes close, but no cigar.
I suppose I have become some-what set in my ways over the years, but I really don't mind.

My claim about the XD shutter is not un-substatiated, but substantiated.

Measurements done by Josef Scheibel ("Applikationstechnische Labor J. Scheibel") have resulted in 1/2300s in A-mode. Josef Scheibel is the most respected German expert on classical Minolta SLRs. For years (I would say at least 1970-2000) he's been a technical expert for Minolta Europe in Germany, and he has published countless books on the SRT, XM, XE, XD, XG, 7000/9000, and Dynax 7/9/7D, but also on the Minolta history. Since he's an engineer who was working for and at Minolta, I completely trust him. He writes about the XD-7 in A-mode:

"Der Verschluss bildet Schlitzbreiten bis minimal 1.5mm (ca. 1/2300 sec) und läuft niemals total geschlossen ab. Dadurch werden auch kürzere Verschlusszieten als der offizielle Grenzwert 1/1000s wirksam ..."
(source: Josef Scheibel: Minolta XD - XG, page 42. Published 1982 at Heering (Ringier) Verlag München, ISBN 3-7763341-2)

"The minimal slot with of the shutter [of the XD] is 1.5mm (which corresponds to about 1/2300 sec); it never fires totally closed [i. e. with a slot of 0 mm]. Therefore shorter exposures than just 1/1000 sec are feasible ..."

This, however, works only in A-mode!!

I've just compared the F2 and the X-700 wviewfinder with the corresponding AiS and MD 2/135mm lenses attached - not much difference when it comes to size and brightness, indeed. The F2 is 100% of course, the X-700 isn't.

The claims I referred to are for the F-3, and not the Minolta.

I thought I was fairly clear with that point, but I suppose not. Wink

The top 1/2000 sec speed is impressive for the F-3's horizontally travelling shutter, and realistic expectations for it may have it a few 1/100 sec faster in A mode, but not a full stop faster in that vintage.

Hope this clears things up.
