Hi Don,
It's really not about being able to see, it's about being able to see well enough to do things like fine focus and so on with bright sunlight behind us and under conditions where actually "no" LCD can do the job.
When you are older or visually challenged (which happens to most with aging) it's difficult to use an LCD to focus. You can compose well enough with an LCD, but even the highest resolution LCD, indeed even a top-notch big screen notebook LCD is too washed out with direct sunlight on it to really see what you are doing.
The Xtend-a-View gives a 2x magnification and completely shields the LCD from the sun providing the equivalent of the next best thing to an optical viewfinder with magnification. Even those of us with less than optimal eyesight can easily see very plainly on virtually any LCD with such a device.
I often shoot with my little Nikon CP990 attached to one of my high quality telescopes at up to focal length of 6,000 mm. It's imperative that I get perfect focus to make a decent image. Even with my full frame dSLR and the very "best" optical prism viewfinder, I can't focus as precisely as with the little Xtend-a-View and the very old and technically inferior LCD on my Nikon CP990 or CP4500!
This really isn't the time or place to launch into an off-topic tirade about the LCD quality of the DP1 or DP2. Actually, it's irrelevant to the subject of this post. If the LCD on the DP1 were the very best available in the electronic industry and had the highest available resolution, one would still need something like the Xtend-a-View to be able to see well enough to do what is desired.
It's an imperfect world and we must deal with imperfect equipment. If Sigma had provided an Xtend-a-View with the DP1 and DP2 then some people would still complain because they had to use it.
Let's not go off-topic here, O.K.?
Best regards,
Lin
How rediculous is this that we have to search and pay extra to see! When did this become our problem instead of the manufacturers? What fools we have become. A lousy LCD should not be acceptable to anyone today period!.
