ctz,
- even though the arTec was designed mainly for architecture/landscape/location photography, it has IMO also its place and interest in studios. However, its longest accepted lens is the 135mm.
- this being said, and since your main work is studio stills and products, I would only consider the "live video" option, certainly not a sliding back with ground glass to make the precise settings needed for those kind of shots (although the sliding adapter can be used together with live video).
- I can't comment on the price comparison with the Linhof, but a p2-p3 conversion costs roughly a 1/3 of a new p3.
Coming to the p3 advantages and features:
- 100% yaw-free camera, as the p2, EVEN for combined tilt and swing (since we were speaking about "yaw-free")
- micrometric geared driven knobs allowing for precise adjustments of either focus, tilt & swing movement or H & V shifts with self-locking drives (no locking of the knobs needed)
- the p3 can be used in different configuration, starting with the Sinar m controlling automatically the CAB lenses via eXposure software (integrated electrical couplings ---> no cables)
- absolute vibration-free exposure with CAB and CMV lenses, due to their integrated between-the-lens electronically controlled shutter (especially important when using multishot like 4- or 16-shot modes)
- can be either used with a sliding adapter or with the back on the Sinar m
- fully integrated in the Sinar modular system (accessories of older Sinar cameras like the p/p2, etc ... can be used with the p3
etc ... ---> a complete and exhaustive description of the Sinar p3 can be found here:
http://www.sinarcameras.com/site/index__ga...72-50-1893.htmlBut what makes the p3 unique, IMO, is what you are asking: yes, the tilt and swing axis ARE inside the sensor area, respectively IN the sensor plane, in an assymetrical way like on the p2.
And the reason why I said that I would use Live Video rather than a sliding adapter is because those tilt and swing axis are very nicely displayed in the live image, allowing the Scheimpflug settings the very same way as it was done on a p2 on the ground-glass (2-point assymetric tilt and swing): nothing can "beat" the easiness, convenience and accuracy of this method when it comes to set the sharpness plane and the focus and eventually the DoF.
Best regards,
Thierry
PS and BTW: the tilt & swing axis could as well be in the sensor plane with the Sinar p2, by using to so-called "Carrier Frame Wide" (not longer available, but could possibly be found second-hand somewhere).
thierry: thanks for input. much appreciated, especially coming from a man who knows the sinar system inside and out.
i cannot regard artec as an appropriate camera for product shots or still life.
it is indeed a perfect tool for architecture and all rainer's and sinar's efforts are showing, indeed, beautiful.
probably this kind of approach will be suited in developing future backs dedicated to this type of studio work. the war is going to be lost to nikon/canons on the fashion/portrait front, eventually, but still it will be a lot easier to defend the product shots view camera front. adding some tilt-shifts lenses to a dslr is not really an alternative to having a proper view camera. and a still-life shooter care less about high iso and fast fps, but still needs a lot better live preview and lens cast corrections.
from what i recall, converting p2 to p3, plus adding a proper head, like an arca cube is not a lot cheaper than having a linhof 679cs in the first place.
i'll be grateful if you can elaborate more on some advantages of p3 vs 679. also it is not clear to me if by converting p2 to p3 you will have the tilt/shift axis inside the sensor area. not having is, imho, a big minus.
