In meinen Sony-Blog-Kommentaren vom 2007-08-07 finden sich auch noch ein paar Punkte, die ich hier mal reinziehe:
http://news.sel.sony.com/electronicsblog/?...howallcomment=1
ZITATEnsure full backward compatibility with 3rd party lenses. I know, the compatibility problems are not your fault in the first place, but still, any old lens being usable on the new bodies will enforce the system "as is". The very matter of a "system" is to maintain the maximum forward and backward compatibility achieveable. If predictive AF, honeycomb metering or AS were impossible to use with such lenses, then switch them off or fall back to less complex algorithms under these circumstances (f.e. the Minolta 9000 AF was slow, but is still able to autofocus even with all the lenses newer bodies will not work with).
Ensure, that the AF indicators in the viewfinder are not switched off for MF-only lenses such as the Minolta/Sony STF 2.8/135 [T4.5], the Voigtländer Macro Apo-Lanthar 2.5/125 SL, the Sigma 8/600 mirror tele or Sigmas old "auto-program" series of AF-mount MF-only lenses. Particularly, I want to use the old Sigma 1.6x AF Multi-Converter to seamlessly use Minolta MD (and Nikon Ai) glass on Minolta AF bodies with full aperture control and autofocus in all camera modes - it works like a charm on the Minolta 9000 AF, so there is no technically reason, why it should not work on newer bodies as well - if you need one of these gems for testing, I would be willing to lend you my sample ;-)
Allow the focus indicators to work with ROM-less lenses as well - you could provide user-configurable lens data profiles for them (similar to Nikon). There are some unique lens designs amongst these old M42 or T2 lenses, and it would add to the system, if they could be used with as little hassle as possible on the new bodies. Pentax, Nikon and Canon all allow old MF lenses to be used on at least some bodies with focus indicators enabled - so this is not a technical problem, but rather a question of policy.[/quote]
Wurde oben schon erwähnt.
ZITATUser-exchangeable focusing screens, with and without split images and microprism collars ("PM". There are still alot of applications, where these manual focusing aids are very useful, if not essential. Don’t forget to offer the great "M" and "ML" screens as well, or even a "PML". There is a significant market for them, you’d see.
Reintroduce STF emulation mode (as in Dynax 7) in new bodies.
Reintroduce depth-of-field preview display (as in Dynax 7) in the new bodies.[/quote]
Wurde oben schon erwähnt.
ZITATReintroduce true stop-down-metering mode in the new bodies. (The Minolta 9000 AF was, unfortunately, the only body featuring this - if you ticked the aperture preview button, it would stop down, but still continued to meter as usual, whereas newer models freeze the meter while in stopped-down-mode. Very useful at times.)[/quote]
Wurde im Verbesserungsideen-Thread schon mal erwähnt.
ZITATIntroduce a user-selectable toggle behaviour of the DOF preview button. And allow to change the aperture while stopped down (some new bodies allow this, but not all).
If the DOF button is pressed while there is no (or a ROM-less) lens attached, the aperture hooking mechanism in the bajonet should stop down to the minimum possible value. This would allow to produce mechanical adapters with auto-stop-down preset apertures - useful for bellows, for example. It worked this way with the 9000 AF, but later bodies simply ignored any requests to stop down when the camera did not detect a ROM lens. I think, it is never a good idea to overrule a photographer's creative intentions.
Introduce a focus trap function, where the camera will release when a subject runs into a previously set distance.[/quote]
Oben bereits erwähnt.
ZITATReintroduce comprehensive timing and intervalometer functions at least as good as found in the Program Back Super 90 / Long Film Back EB-90 of the 9000 AF.
Reintroduce user-selectable multi-spot metering and selectable average, center, highlight, shadow and possibly other strategies as useful on digital cameras.
Reintroduce external flash/ambient light metering with remote data transmission into the body (as found on the 9000 AF in conjunction with the Flash Meter IV and the Data Receiver DR-1000). Using today’s technology, this could be made much more easy and flexible to use than it was 1986.[/quote]
Aus dem Verbesserungsideen-Thread.
ZITATReintroduce individual honeycomb metering cell display (as in the Dynax 7) in new bodies.[/quote]
Oben bereits erwähnt.
ZITATMake the directional characteristics of the metering cells compatible with shift/swing/tilt lenses again. (The 9000 AF, again, could meter correctly even with shift lenses in the most extreme shifted positions with an error of less than -0,5EV, the 9xi had an error of up to -1,5EV, the 9 even an error of -2,5EV here. This makes it unneccesarily complicated to use such lenses on newer bodies…[/quote]
Schon mehrmals hier im Forum erwähnt.
ZITATIf you introduce SSM lenses, then introduce a dual AF mechanism (as Pentax did), so that those lenses could still be used on non-SSM-enabled bodies with AF enabled. I can only speak for myself, but whilst I would be willing to spend quite some money on new Sony/Carl Zeiss glass, I won’t buy any lenses I could not fully take advantage of on my film bodies. Introduce SSM only for lens designs, where it really makes sense (e.g. large telephoto lenses with huge moveable masses, complicated multi-floating elements in zooms, macro bellows/retro mounts, shift/tilt lenses).[/quote]
Aus dem Verbesserungsideen-Thread.
ZITATI want the knobs back! :-) Don’t step back to function-overloaded push-button interfaces - that’s just not very ergonomical. One easy distinguishable control element for every function rules. Ideally, the controls would resemble classical controls, IMHO. The Dynax 9 and 9000 AF were almost perfect in this respect (although different in concept), whilst the Dynax 9xi was horrible to use for anything but mainstream applications.
Built-in flash even in the flagship model - similar to the Dynax 9. As it looks now, the flagship model may not come with a built-in flash, which would be a bad move, IMHO.[/quote]
Oben schon erwähnt.
ZITATHave user preset profiles "1″, "2″, "3″ also on the flagship model, right next to "P", "A", "S", "M" (but no "subject programs", please ;-).
Have a look at the Pentax K10D, which features a number of interesting new automatic modes such as an ISO automatic.
Possibly introduce a depth-of-field "assist" mode for the "P", "A" and "M" modes, where you would point at two subjects in different distances, and the camera would preselect an aperture so that these two subjects will be inside the depth-of-field. Sure, the photographer should be able to override this later on, just as in the normal modes (hence an assist mode on top of the regular modes, not a seperate new mode).[/quote]
Neu.
ZITATWeather-proof body and lens design.[/quote]
Erfüllt.
ZITAT(Near) full format sensor size - I understand, that APS-C may be a necessary but hopefully only temporary compromise for price constraints, however, personally, I’m not at all interested in significantly smaller sensor sizes then 24×36, and I would just (and happily) continue to shoot on film then.
Live-preview, but without giving up a bright and large 100% high-eyepoint optical viewfinder similar to the one found in the Dynax 9. EVF designs would be a reason to stay away from the camera for me. I’m not a videographer - and don’t want to become one.[/quote]
Schon erwähnt.
ZITATAF similar to Dynax 9 autofocus performance again, please.[/quote]
Offenbar fast erfüllt.
ZITATReliable flash exposure (similar to Dynax 9 or Dynax 7 performance, not as found on the DSLRs)[/quote]
Unbekannt.
ZITATSupport of the DNG file format. Fully documenting the RAW file formats used in your cameras will help you to build up trust, as serious photographers willing to use your DSLRs will depend on the availablilty of converter support for many decades to come. There’s not much point shooting digitally (except for point-and-shoot) until this issue has been resolved.
Support for Compact Flash cards, SD cards and USB sticks. Support for two storage media at the same time in order to create redundancy in case of a media fault. In other scenarios, it may be useful to temporarily "double" the capacity or exchange one media while the other is still being written to - this will help reduce idle times to a minimum.[/quote]
Oben schon erwähnt.
ZITATNo dangling (and easy-to-break-off) "rubber caps" for interface connections, such as USB etc. Use real (weather sealed) spring-loaded plastic doors as used in previous models such as Dynax 9.
No non-user-serviceable backup batteries inside the body - all backup batteries should be changeable by mere mortals. Unfortuntely, the Dynax 7 and 7D have built-in batteries - this was not a good idea at all. Noone should have to depend on the service department in order to change backup batteries in 5 or 10 years time.[/quote]
Schon mehrmals hier im Forum erwähnt. Der zweite Punkt auch im Verbesserungsideen-Thread.
ZITATProvide options to use NC & NiMH rechargeable AA cells or primary cells (even at reduced speed). I would not want to trust on LithIon or LithPolymer batteries as the solely available power supply option. These batteries will die after 2 - 3 years, even if not used and just stored away. (This is not a Sony problem, but a matter of this battery technology in general.) While this is not a problem now, it will be one in ten years time, as it will be impossible to find replacement parts by then. Even if I may use a newer camera then, I still want to be able to use my older cameras if I’m in the right mood. If I cannot be sure in advance, I won’t buy it at all.[/quote]
Oben schon erwähnt.
