One year retrospectives (tech camera)

Agreed! f8-f11 is ideal, F16 is a noticeable step down. F22 is unusable IMO.
For my SK 43 XL, I do not get past f/11. According to Rodney, he got post processing skill to take care of of loss of resolution in the field. Rodney's prints proves that.

His work looks fabulous, although hard judge "sharpness" from website images. Of course, subject matter will have much to do with what aperture you want to shoot as well. Curious as to what PP techniques could be used to salvage diffraction related sharpness loss though

To a large degree diffraction softness can be fixed or at least greatly improved using deconvolution sharpening. Personally I use Piccure+ but then again I have plenty of time and processing power on my hands for those images that need it (it's glacially slow but can dramatically fix certain images).

I would also caution the degree that you consider an image with slight diffraction at 100% in Photoshop vs a fully processed PRINT with the appropriate levels of micro contrast and output sharpening applied and viewed at normal print viewing distance. They can be vastly different.

TBH I'm as guilty as any other tech cam shooter and try to use the optimum aperture for my lenses but that can sometimes produce optically perfect but ultimately boring images. If I need to open up or stop down for DoF purposes then I don't hesitate to do so.
 
So I think the electronic parts could survive quite long in such a camera body.
We can't even be sure whether we will be able to purchase new batteries for the ALPA 12 FPS in 20 years' time. The ALPA 12 SWA is still functional today, about to celebrate its 20th birthday quite soon.

What's the story with the supply of Copal shutters now? Does anyone have any news about a replacement? Like Anders, I have a Linhof Techno and am a little worried about how this one will pan out.

As I understand the situation Copal shutters have ceased production but the likes of Rodenstock still have stock (I just bought new 32/70HRs with Copal 0 new from the factory without any problems). There are plenty out there but ultimately new stock will dwindle.

Also, there are plenty of repair shops that will always be able to service the many thousands of mechanical shutters out in the wild. However, I recently tried to purchase a replacement sync post part for a Copal 0 shutter and the web dealer who specialised in spares had just had his entire stock of spare parts bought up ... I ended up getting the part fitted by a local repair shop but bits are getting more expensive ($25 for a sync post for example).
