Please excuse me for being terribly rude, but are you people stupid?
Rangefinders don't need bright lenses beacuse you do not focus through the lens.
Lenses that are fast are bigger and heavier.
Slower lenses are not as 'unsharp' wide open as fast lenses are. Shooting a modern f2.8 lens at f5.6 or an f4 lens at f5.6 will give the same sharpness (or close enough).
Do portrait lenses need to be sharp as hell anyway? You probably won't be putting your camera on a tripod...
You're the only one using the word "bright," so perhaps your namecalling is misdirected? Maybe you're not so "bright" after all.
It has nothing to do with focusing through the lens. It has everything to do with limiting a 'portrait'-length telephoto lens to 'non-portrait' apertures. This would probably be the slowest of contemporary primes. The discussion is about whether that makes sense, and to whom this lens might be directed. I don't think you're educating anyone here about the principles of photography.
Whether or not this is a smaller lens than others in its focal length is another matter for discussion. It doesn't look appreciably smaller. Whatever. I'm not sure how small you need your lenses to be anyway. I routinely see petite girls carrying SLRs, while the rangefinder crowd whines about tiny RF lenses.
Your comparison of max apertures is sorta moot since you're not really talking about max apertures. We shall see if this f4 lens performs as well at f4 as it does at 5.6 and smaller, and also whether it performs as well as an f1.4, f2, or f2.8 lens does at f4. Whatever the results, f4 is still too limiting for my purposes.
Yes, for my purposes, "portrait lenses" do have to be sharp as hell. I don't like Olan Mills/Sears/Strip Mall portraits. I don't always shoot 'mature' women. And, again, there is also the 'added benefit' of a lens that opens wider, if the wider performance is less than when closed down. Shoot at wider/softer apertures for less harsh results. With your theoretical lenses that are consistent from 4-64, you have no such choice.
