I am considering to spend more time on macro photography of everyday items, centimeter sized, in most cases larger, say 5 cm and up. (No tiny ladybugs etc). Photography authorities say a macro lens is required.
But maybe a sigma dp3 quattro can be used?
According to the specs and some reviewers, it has a manual focus mode, the minimum focus distance is ~22 cm, it is a tele lens.
Possible drawbacks are: There are no ring flashes (made by Sigma) for this camera. The sigmas are notorious for being noisy at ISO values > 100, and many macro shots require a lot of light (or high ISO).
Note that I know this camera is not marketed, and not even designed for this purpose. It is more a point and shoot camera for the slow, conscious photographer. But I like to hack and tweak things.
An obvious alternative would be to buy the dedicated macro lens for my main camera. But I have already a portrait telephoto prime-lens with a similar focal length. So buying the macro would be redundant.
