Hi everyone, I've some questions that makes me thinking in a circle for a while, hope you can help me out.
1. Why is there so few wide lens that has a fix F2.8? Is it really so difficult to create a lens with a fixed apature?
2. I see that some wide lens have macro feature. So can a macro lens use as if a wide lens?
3. Are wide and macro 2 entire different thing even though the focal length remains the same?
4. How does focal length affects the DOV ? Let's assume 35mm@F2.8 and 70mm@F2.8?
Thanks for all the effort!!! :cheers:
