I was merely wondering if my 1200 some images over the past 7 months was sufficient usage.
How many images in total did you shoot over the past 7 months? And, how does your 16-35 mm usage compare to the rest of the lenses you use? That will answer the usage question but not the issue of sufficiency. Of the images you take with the 16-35 mm, what proportion of them could you have made with other lenses you own? Or, reverse that, and ask what proportion of images do you make with the 16-35 that you can ONLY make with that lens and how critical are those images to your work?
I have analyzed all that, I answered most of those questions before I bought it.
I was asking what usage others see.
How much do you use yours?
Last years usage was low due to my hand surgery, so the data is likely not all that useful after I bought the camera. Only about 7000 images since I've bought it. Hopefully, as my Carpal Tunnel heals, I'll be out using my camera a lot more.
I fo have a 15mm FE and a Tokina 17mm f/3.5 prime that are very good, but f/2.8 seems to be on the margin.
