It's a very thin lens, something like 1/3 of the already small 50mm F2.0.
The optical formula is 5 elements in 4 groups.

| Pentax MX and the 40mm pancake |
The lens is very sharp when stopped down and acceptable wide open. Not the sharpest lens from Pentax if you plan to use on digital, but perfectly adequate for film.
Not the best lens but it's outrageously small and light (110 g), making it a good option when you need to keep thins at a minimum weight.
The new Pentax DA 40mm for digital has nothing to do with this lens, besides the size and look.
