One camera with one lens for general photography, is the macro as good?
Conclusion... Unfortunately for general photography I think the standard 50mm f1.8 lens has a slight edge over the Nikon f2.8 macro lens (but only just). Its also slower and more bulky. What about the difference in the field between a 60mm and 100mm macro? I would go with the longer lens in most situations unless a wider field of view is essential.
Just a very quick lens test (1 hour total) to see how these 3 lenses compare in resolution, contrast and colour at f10. The first set are straight out of the camera. The 3 below the first set are whole images with slight curve adjustment.
Conclusion... They're all good lenses with similar results when used at optimum aperture in flat light.
The Zeiss ( f2 ) may have a slight edge in certain lighting conditions but only goes to half life size.
Slow growing and just out in leaf this week - Nothofagus gunnii - Fuscospora gunnii is very rarely seen in cultivation - It is the only deciduous tree in Tasmania. The name was changed in 2013 by some but not all have accepted it. See link to the plant list where it remains Nothofagus
