Sigma 60-600mm - Performance from a calibration view point
What were we expecting?
- Well, to start with greater consistency as in not having to dial in to the dock such large correction numbers (auto focus micro adjustment values) especially at 600mm.
- The ability to calibrate at additional focal lengths as in 300mm and 500mm.
- The lack of “wobble” at 400mm.
- Greater and/or additional lens functionality that can be applied to C1 and C2 settings.
- But most importantly not having to convert your calculated AFMA correction figure to their system used in Sigma USB dock software So all in all a big ask, how did this new superzoom deliver?
So, all in all a big ask. So how did this new superzoom deliver? – Read on for our initial evaluation.
Our first surprise….On opening the Focus settings menu (this is where you add the calculated AFMA values for focal lengths) we were surprised to see the lack of focal lengths supported, in this case a huge gap between the 200mm and 600mm
So with the 60-600mm there is no support for 400mm, let alone 300mm or 500mm.
Our second surprise...
was the lack of additional functionality with regards the C1 and C2 lens settings, these were the same for both lenses, Sigma perhaps missed a trick here.
We would have liked to have seen additional stabilisation in the lens, past the claimed 4 stops, to rival the best “in body” stabilisation systems, but we can always dream…
The one improvement....
we were pleased to see though was the fact that with this new lens, unlike others in the Sigma range, it was not necessary to convert the calculated values from Reikan’s Focal software / Canon’s af micro adjustment / Nikon’s AF Fine Tune menu before entering the numbers into the Focus settings menu*
We also found that this particular example needed less in terms of correction, especially at the 600mm end than the 150-600’s that we see. This of course could be a one off and a more accurate assessment can only be made over time and with more examples.
To be brutally frank we were disappointed. Obviously we approach a review from a different angle to most. Some decent examples a linked below. It offers a phenomenal focal range for the price and this should not be undervalued. However when Sigma hold approximately a third of the lens market they should really have pushed harder with this one. Less focal point that can be calibrated is really a step back. So whilst we do see many 150-600mm lenses needing calibration
*Calculated AFMA values must be converted in order to maximise lens front / back focus correction when using the Sigma dock.
