Originally posted by causey I had the 40mm, and I plan to get it again. It's a wonderful lens, tiny and relatively inexpensive. I know its bokeh is better than that of the DA L 35mm. However, I find the 40mm to be a bit too long in many everyday/street contexts. It's too nice a lens not to have (and I'm not interested in macro, so I don't need to spend $500+ to get the DA ltd.). I suppose the DA L 35mm will be around $170 in less than a year, which is cheap enough to get it for the situations in which the 40mm becomes restrictive (although I use a Tak 35mm, and I find it very nice). The DA L is 'optional for me--it depends on how cheap it can get.
OK, since you know you want the DA 40 (good choice, I tried not to be too pushy), I would suggest something complementary. I really see the 35 being too close to the 40.
Give your kit lens a go at 28mm. It's a really nice focal length on digital (a loose normal), and is much more forgiving in tight quarters than 35mm.
The 28mm gives me a really natural look. It's very close to the FOV of the FA 43 on film, which is what the FA 43 was designed for. The A 28mm 2.8 has rather desaturated colours, but it is very sharp if you nail focus.
I'm just saying that it makes sense to space your primes out so you have a series of specific tools. I can make the 40mm work indoors, but when I can't, I know 35mm wouldn't work either but 28mm might get me there.
The 28mm is the "other bargain"... there are other lenses that are wider, but much more expensive. The 28mm is an outright steal if you are ok with manual focus... the FA 28mm is less tempting, but still a more useful focal length paired with a 40 than the 35.
EDIT: You already have the 28! The 40 is a no-brainer (in my little brain!).
