Are there any mirrorless cameras that provide exposure metering information while ISO is being set? Every mirrorless I have (P&S or ILC) will not meter during ISO adjustment, so if I want to set ISO last after aperture and shutter speed (which is what I usually prefer to do), I have to adjust blind, as sort of a sad throwback to film days.

Fortunately, my dSLRs don't have that problem, but I'll bet it's more because dSLR viewfinders are intrinsically so primitive compared to EVFs more than any forward-thinking on the part of the manufacturers. Whatever the reason, I'll take it in the dSLRs, but wish I could find a mirrorless that did it.

Because many people use their camera HEAVILY or like to print large and/or need to crop deep, and can use many of the features available in upper end cameras like weatherproofing, high MP sensors, multiple memory cards, faster and more accurate AF systems, external settings controls rather than menu based controls, much longer shutter life expectancy, and a plethora of lesser reasons. One needs to choose a camera that meets THEIR needs, not the needs of others. If a $300 camera will do the job for you, then by all means get it. If it won't do the job, then buy one that will. Simple.
