Personal Preference to be honest.
If you like bokeh & super shallow depths of field, primes will give you WONDERFUL results. It's tough to get versatility for pleasure. I'd love to see a zoom @ 1.4 but it'd probably be about +/- 5lb's for say a 24-70.
Zooms on the other hand ARE wonderful tools. You're not locked to moving around like a banshee when stuck in certain places where you are quite restricted.
The primes will give you amazing IQ & Bokeh / DOF
The zooms will give you amazing versatility but gain a lot of weight.
Zooms
- 70-200mm f/2.8L IS II - 3 1/4lb - $2,499.00
- 24-70mm f/2.8 - 2.1lb - $1,499.00
Total = 5.35Lbs - $4,000.00
Primes- 35mm f/1.4L - 1.28lb - $1,399.00
- 85mm f/1.2L - 2.26lb - $2,199.00
- 135mm f/2 - 1.65lb - $1,039.00
Total = 5.19Lbs - $4,640.00
Both not too far off from each other in weight & price.
Ask yourself a few questions.1.Do you have 2 bodies?
A.If only 1, is it FF? (If only one body, in most instances I'd suggest a zoom for versatility)
B.If 2, are they both crop, FF or a split? (Nice because you can strap 2 lens' up and only switch the use of ea camera)
2.Do I shoot wide open a lot?
A.Do I NEED the bokeh / shallow DOF? (into bokehlicious dishes? haha)
3.Do I shoot low lighting situations? (Weddings? Basketball Games? Concerts?)
4.Is this going to generate some sort of income?
