yes you are right, unfortunately the next dealer who could have arca equipment on stock is about 1000km/621miles awayBTW, this is one of those things that needs to be experienced first-hand to see if it fits your style and needs. You really should work with a dealer and get a full demo of a unit.
There is a micro SD card that your dealer can reprogram for new lenses. As far as I understand, you swap the SD when you get the new lens. I would still prefer a proper user updatable USB solution, but this sounds quite workable.It is my understanding that it is best if the eModule Cloud you order comes factory set for your specific lens kit. I would not think one would want to send the eModule back each time they added a new lens; so, it may be a good idea to have a clear vision of your final lens kit when you order.
Even ideal live view (i.e. 5D3 on a big monitor) cannot do as precise/repeatable a job of hyperfocal focusing as the Arca can (by sheer accuracy and tensility of the helical mount). With the eModule indicating hyperfocal in real time and with the same precision/reliability this is now arbitrarily easy (once you or a dealer dial everything in calibration wise).In 5 or 10 years down the line, if/when live-view is just as good as (or better than) current pro DSLRs, I think this e-module will likely become obsolete. But, if A-S adds VarioFinder functionality (with parallax adjustment) and in-viewfinder focus confirmation, then I'm not so sure
Thanks Rod - I think this is the bit that I struggle with. I was attempting to manually focus the Mamiya 300mm f/2.8 on a Phase One AF recently (quite close to minimum focus distance) and found it really tough - even with the focus confirmation, I had to shoot and then fine-tune manually based on what I saw from the focus mask and then zooming in 100%.Gerald, et al,
You focus as you would if looking through a telescope. It is telephoto allowing you to look at less than the whole image you will be photographing in most setups. It is a multi-coated lens so has excellent contrast and even in low light is quite easy to focus.
To do what you suggest, you would use it as a range finder first, hand held, and determine your distances for, say, near and farthest items you wanted to be sharp. Then connect the module to the camera and set focus so that DOF covers the distances of the objects selected at the appropriate Aperture.Rod,
thanks for the explanation. Much clearer now but I still don't understand it completely:
Can you 'swing' the eModule while it's attached to the camera body or how does it work if, within your chosen frame, you want to focus on something else? It seems to me that it's firmly attached to the body but in this case one would have to select the new point of focus by moving the camera and hence changing the setup.

You mean basically like every other focusing camera on the market?It seems to me that it's firmly attached to the body but in this case one would have to select the new point of focus by moving the camera and hence changing the setup.
I think this statement depends on the level of accuracy that you require. If you are shooting a general landscape with wide angle lenses, then what you say here is probably true in most cases. However, if you really need to have a specific plane of focus to be its sharpest (for example, to extract all the nuances of micro-texture within a facade) or in situations with longer focal length lenses, then there is no substitute for a laser like the Disto, which is accurate to within 2mm out to distances of 200m.The cloud negates the need for say a Disto rangefinder as it both can do the RF's job and then can be used to set the camera's focus.
On the contrary David, I think Torger has a very valid point.Torger, what you say above is simply not true.
