The preset Switar lenses on my H8RX4 are pretty fast, too; f 1.3, 1.4, 1.6 depending on the lens.
That's right. For many applications it isn't worth more money, except the 26mm and 75mm are preset macros (in 16mm) therefore can do extreme close ups.
It is handy. You can look at the light meter, set the lens at the correct F stop, and then open wide up to focus and get the subject in view. When you're ready, you just turn the lens while still looking through the viewfinder back to the f stop already set... it stops there automatically (it won't go further).
The knobs make the lense a little more bulky though, and the 26mm is a bit bigger than the 25mm non preset. Slighter faster too, as noted.
