We tested the lens on a Nikon D750 body. The lens balanced very well but those with smaller hands may find the combo a bit on the heavier side. In spite of the focus confi rmation dot in the camera’s viewfi nder, manual focus confi rmation was a bit diffi cult due to the super-wideangle’s extended depth of field (the infocus confi rmation dot can come ‘on’ even when the lens has not achieved perfect focus). But then this cannot be considered as a lens fault.
Autofocus was fast and accurate but please note that the camera body also plays an important part. Darkening of corners with the lens wide open at 15mm was negligible, which is very impressive.
The lens exhibited noticeable barrel distortion up to 20mm setting. At 24 and 30mm settings we did not notice any distortion. Flare was very well controlled and a negligible amount of chromatic aberration could be seen but only when we really tried to search for it. In terms of image sharpness, the Tamron SP 15-30mm f/2.8 Di VC USD impressed us. Images were sharp at all apertures and all focal length settings, with the usual slight drop in corner sharpness at the widest aperture. The sweet spot appeared to be around f/5.6. Overall, we were very impressed.
