I traveled for a wedding this last weekend. I took with me a DA17-70, a 28/2 and a DA40. I did use the wide end of the 17-70, but most of my photos at the wedding reception were taken at or near 70mm with the zoom and AF540. My DA17-70 works quite well at larger apertures, but I missed my FA77. Were it not for the walking around parts of the trip, a better and lighter combo would be to take the primes and leave the zoom. The 28/2 (mine is a Kiron) is a great indoor lens at just the wide side of "normal" and fast enough to use available light, and it has a nice DOF.

I love the DA* 16-50. It's a little weak at the wide end (16-18), but pretty strong everywhere else. I still use my FA 50 though. The whole point of primes is not necessarily image quality, but wider apertures and smaller size. I would only put the difference at one stop between the lenses (I seldom shoot less than 2.0 with the FA). The biggest problem with the 50 is that it is a little long for indoor shooting.

Hello everyone,

I have a Pentax 50 1.4f prime. The one that costs between $200-250.

I have been reading up on the 16-50 f2.8 DA* and have been very impressed by it. Do you think this DA* 2.8f lens can replace my prime? I have a kit lens for my K10 and this prime, but I'm thinking about selling both of these lenses to upgrade to the 16-50 2.8f DA* to replace both lenses. Can this work? I take lots of indoor photography and thought this DA* lens can relieve my lens changing.
I have both lenses and in my opinion they cannot be compared.
The 16-50mm is MUCH more versatile, the FA50mm 1.4 can be used with less light, however the shallow DOF can be a real problem then. Especially since autofocus is not that great in low light.
A good flash (indirect / and or dispenser) is sometimes a good alternative to go with the 16-50mm also. F50 is often too long indoors as well.

I'd say, make sure you own them both. No, don't sell your lenses. Hang on to them.

It mostly depends on whether you shoot indoors with or without flash. With flash, like with most digicams: 16-50 should be fine.

Without flash: the 50/1.4 is better.

Look at your shots and tell yourself what works for you best. The best solution is to save up an extra $200 and buy the 16-50, and keep the 50/1.4.
