While I generally agree with you, one area where a slower lens can’t compete, even in broad daylight, is the rendering. An f/5.6 lens will never look like an f/2.8 lens will in terms of isolating the subject.Yup.
I think there are some on the various forums that think ALL of the consumer/non-pro lenses are JUNK.
Maybe they have a 50 inch monitor to look at the images.But for many of us, the consumer zooms, when used within their limits, work just fine.
As I tell my students, you don't NEED a $3,000 pro lens to make a 2x3 INCH picture in the yearbook.
It is about matching the photographers needs (not wants) to the gear.
- If I am shooting a football game in broad daylight, I may want a pro 70-200/2.8, but I do NOT need it. A good consumer grade 70-300/4-5.6 would do just fine. There is PLENTY of sunlight for the slower lens.
- If I were shooting at night under lights or in the high school gym, that is a totally different story. Then I would NEED the faster f/2.8 lens, in order to not be shooting at ISO 12800 or 25600.
- Or a camera that has GOOD high ISO performance, in order to use the slow lenses.
- I told my high school AD, at night and in the gym, it IS about having the right equipment, for the LOW light level.
