how about my ef-s 10-22 combo with prime like sigma 35mm f/1.4 & ef 50mm f/1.4. but i thought it become more challenging because i never use a prime before. i just use my 10-22mm for landscape & 18-135 for general
Primes are nice although I would suggest getting them one at time to see if it works for you. I currently use primes for the midrange and zooms for the wide and telephoto focal lengths.
