I just purchased the neatest Technikardan camera from Kumar for a reasonable price on the LF site. (See photos.) Until his listing, I'd never seen one of these cameras. They are slick! All movements are very smooth, the camera is relatively short vertically, and it will just fit collapsed (1st photo) in my somewhat oversized MEI backpack.
There's so many things that I like about this camera. I can adjust rear rise/fall in back with one hand, versus two. (I will raise the front more than needed, so that I can home in on the desired rise using the rear standard.) It fits directly on my D4, Arca Swiss tripod head without having to add any kind of quick-release plate, allowing me to easily center the camera on the head. It's a one step process.
I like both the wide-angle and the standard, double tapered bellows that can be used with this camera. However, as Kumar advised, the standard bellows was riddled with pinholes. (I didn't know a bellows could have so many pinholes.) So, this standard bellows is currently on its way to Custom Bellows in the UK for repair. ($200+shipping.) In fact, I've asked Keith there to make it in the best way possible with durable materials and possibly wider pleats, versus in the way likely needed for the collapsable rail on a 45 or 45s. While I was impressed with the 45 and 45s Technikardans for the design and the smoothness and convenience of the controls, I largely ignored the camera because of its collapsible rail. (This rail causes multiple problems.) On the other hand, the rail on this camera is super-durable and solid. At 15" unextended (up to 19" lenses when extended), it's also a bit long. But, it'll just fit in my backpack. I've ordered the compendium lens hood for short lenses on EBay and will likely use the Lee compendium for longer lenses. Sweet.
I've been a fan of my Arca Swiss 4x5, since I purchased a Classic F in 1994 for $450 at a swap meet. But before long, all my Arca 4x5 equipment will be sold and gone. Though, I still have my very nice Arca Metric 6x9 camera for MF.
When I receive the extra gear that I've ordered for this camera, I'll post (better quality) photos in a subsequent thread.
