Choose between DA 40mm ultra v. SMCP-FA 50mm F1.4

'Lo all,

I am looking into upgrading my lens and am trying to choose between the DA 40mm pancake and the SMC-P FA 50mm F1.4. The prices are relatively similar, especially with the recent $50 rebate offered by Pentax. Does anyone out there have an opinion one way or another? I would use this for general photos, indoor photos under marginal light, etc.

Thanks in advance!!

As good as the 40 is, under marginal light, you may find it to be to slow. The 50 as a f1.4 lens offers 2 stop advantage. There is also the 43mm f1.8 limited, which is also superb.

Marginal Light=50mm f/1.4! I believe the only advantages of the 40mm pancake is the size and the quick-shift focus. Two stops of light is alot to give up...

FA 50mm f1.4 hands down, no contest, it's the better buy!

Ditto!! Da 40mm seems pointless in the current market of lens variety ...

I own both lenses. The DA 40mm is a superb walk around lense. IQ is wonderful and the weight advantage of mounting it on the lightweight K100D are obvious. Additionally, CA on this lense is quite low. This is my preferred lense for the times I pack the camera in the suitcase for business travel.

The FA 50mm is also a favorite of mine. I love the low light abilities of the lense and the softness of the images when it is opened up in very low light. It weighs somewhat more than the 40mm Ltd but still is not a burden when mounted on the K100D. I might also note from lense tests found on the web that CA is much higher on this lense than the DA 40mm.

While the focal lengths are similar, I have very different uses for each lense.

Agreed, in difficult high contrast situations I would have thought the 40mm would have the advantage as it really has little tendency to show CA..

Thanks!

I found that most of the pics taken with the old 50mm prime have been indoors and in situations where my P.O.S P. and S. woul d have erased most of the color from the intended target. I really like the natural light ability of SLRs and capable glass. However, for walking around, sometimes the 50mm is a bit closer that I would like - hence looking for something that is a bit wider. While the DA is a solid piece of glass, I'm not sure it isn't more of a novelty item compared to a functional lens. I suspect I'll wind up with the FA 50mm in the near future. Thanks for putting up with the noob-question and all of the replies!

The 50/1.4 is the best bang for the buck in terms of image quality for the money, bar none. That said, I finally sold mine because while it is indeed a great lens, it just felt cheap and plasticky next to the DA and FA limiteds. It may be twice as much as the FA 50, but I'd go for the FA 43. That's next on my LBA list, anyway...

Have you considered the FA 35 f2.0? Supposedly very sharp and nice.
