Q: 5. What is 35mm aperture equivalent?

A: If I understand your question you are not asking about the field of view, which is 35mm equivalent, but the aperture. If I am not incorrect, a f/3.5 is a f3.5, it requires the same amount of light as a 35mm lens, stopped down to 3.5. But the DOF is not the same. I never thought about it and couldn't find examples, so I played with a DOF simulator using the X1D vs 5DmkIII since I think it represents a standard full frame, and I found:This 45mm at f3.5 on a medium format camera gives the same DOF as a 35mm at 2.5 on a full frame camera (based on my research). So I guess it's not like a 1.2, but I have used it a lot and I can tell you, it's a stunning lens, you won't find people asking if you can get a shallower DOF, they will just remark on how amazing the photos look. The 90mm 3.2 is also an amazing lens.

A: the DCR 250 is great way to explore the world of macro if you're on a limited budget, The Raynox DCR-250 is not a dedicated lensmeaning you cant attach it directly to your camera. Youll have to clip it to a lens with a filter size between 52mm to 67mm. The clips grab on to the internal ring on the front lens element. if your sense is smaller than 52 mm you'll need a step down ring. also check that you can add a filter to the lens. What is so great about the Raynox DCR-250 is that you can easily clip it to most lenses and instantly increase your magnification power
