70-200: Turbines and tripod collars

This evening there was a beautiful lavender sky, so I headed up to my local windfarm to try to make the most of it. What follows is a pair of shots taken with the Tamron 70-200mm f/2.8 SP Di VC USD. Both were tripod mounted, and the second shot was actually underexposed during shooting to maintain the shutter speed I wanted. You can see that even shooting full frame, there is no loss of sharpness at the edges of the frame.

On the subject of tripods, I’ve not mentioned the tripod collar before. It’s a removable, wrap-around design, with a large release knob. I’ve found that this is easy to use, and doesn’t have to be tightened all the way to give a good grip on the lens barrel. The foot itself is a wide-based unit, which sits very well in the hand if not on a tripod, and makes for easy adjustment of the manual focus ring. When used as it’s designed, the large surface area makes good contact with your choice of quick release plate. There is a non-stick pad on the inside of the collar, which made for easy rotation of the collar when straight out of the box. However, I have found that over time, the adhesive which holds this pad in place will work its way into the groove for the collar, and I’ve had to maintain smooth running with a little light oil.
