As zooms cover around 90% of my shooting, therefore I use a D-Xenon 12-24 + DA 17-70 + DA*60-250, I do find the overlap useful. I've only recently added the 12-24, so I'm getting to know it and how to best use the wider FOV.
I only find prime
macros useful as they combine the best IQ
and close focussing ability, therefore I have the FA 50/2.8 & D-Xenon 100/2.8. They cover pretty much all of my portrait, flower and bug shots! I sold off all my other primes as I got fed up with continual lens swapping and I never found shallow DOF useful. I did have decent primes, an FA*24, FA 35 and FA*300 f4.5, the FA*300 was probably my most used prime. I also spent 3 months working with the 21, 40 and 70 pancakes and I've never regretted my decision.
I still have a strange hankering for the 10-17 FE though!
