This question already has an answer here:
I'm new to cameras with interchangeable lenses.
I'm looking at a 18-200mm zoom lens or a 55-210mm zoom lens.
I already have an 18-55mm lens.
Is it fair to say that an 18-55mm lens, combined with a 55-210mm zoom lens, will give me the same "zoom range" as the 18-200mm lens? (Ignore the fact that the first is 210mm, and assume it's a 55-200 for the same of this question).
To get the zoom % you would take 200/55 = 3.63 X Zoom 200/18 = 11.11 X Zoom
The first has a lower zoom ratio, but that's only because the lowest field of view is 55mm which would be the exact same field of view at the highest zoom of my 18-55mm. Meaning it picks up where the 18-55 left off.
So, an 18-55mm and a 55-200mm would provide the exact same field of view and zooming options than a single 18-200mm lens. The only difference is having to swap between the lenses.
Based on what I understand I believe this to be the case. Am I spot on? Is there anything else I should be considering or be aware of?
Both lenses are Sony and will be fitted on my new a6000.
