The 40mm f2.8 verses a f2.8, 16/17/18-50mm, zoom advantage is going to be in AF speed. The 40mm is said to be one of the fastest focusing lenses on a Pentax DSLR.

The 35mm f2.8 macro buys you a 1:1 macro which will be better than the 1:3 - 1:4.7 of the zooms.

The 21mm is a hard one to justify without owning the 40mm and 70mm in my opinion. I personally would skip the 21mm and get the 15mm f4. Its claim to space in the bag being it is the smallest wide prime around. With the new Sigma 8-16mm lens doing so well in the reviews, I probably would skip the 15mm and go with the Sigma.

Thank you
Russell

Sell the zoom, then you will have to get the primes
Seriously, IMO each limited prime offers something that a zoom cannot.
I'm not sure what the quality of your 2.8 zoom is like, but I would say that most of the primes you are talking about will have better IQ.
They also have a metal body (sounds petty but I don't like plastic lenses!), and often are better in terms of CA and flare resistance than the closest zoom.
The wide angle primes often have less distortion than a zoom at that FL.
And yes, the DA35 also gives you macro AND incredible sharpness.

After some "heated" discussion, i think i obtained the approval to land a DA35 Ltd. I was only allowed just this prime at this stage until i can demonstrate that my photography skills is good enuf to earn another prime

That will be a tough test for me

The biggest benefit of primes to me is smaller size. The Da 16-50 is pretty big, while if I put a DA 35 or 40 on, suddenly the size of what I am carrying drops by 50 percent. Primes do have better bokeh as well.

Congrats on receiving approval. The things we do for love LOL!

When the lens comes, take some macros of her engagment ring in a well lit room with a dark shirt or fabric as background. Show her the best ones. This may help release "additional discretionary funds".

Enjoy, it's a great lens

Does your wife work for my HMO? Seems I've had almost that same conversation several times already in that context.

The key is to get yourself appointed Finance Minister. But that might require a coup, and you thought camera lenses were expensive. Plus, you may very well land in the gulag for crimes against the government. And no way will you get to keep your camera equipment.

For me, I do notice that I need to stop down a couple of stops to be tack sharp with just about any lens. I really appreciate a more narrow depth of field sometimes, so I like that my 50mm 1.7 gives me the ability to shoot tack sharp at 2.2, whereas my zoom 2.8 wants me to stop down to 3.5 for tack sharpness.

you can take a small prime and shoot all day, whereas a large zoom will feel heavy in a couple hours

didnt Canon used to make a 200mm f/1.8?

I would say it was best of both worlds.
Yep, but it was replaced by the 200mm f/2 IS. Pretty expensive lens at around $6000.
