- Engage the “Flex Zoom Lock” and thank me later.
Starting at the outer end of the lens, there’s a large, rubberised zoom ring that can move from 150mm to 500mm in a 75-degree twist. While there is a zoom lock switch on the side for 150mm, what you may not notice is the “Flex Zoom Lock.” By pulling out the zoom ring, you’re able to lock it at any focal length. On moving wildlife, this is a serious treat!
- Get in super close without losing (a lot) of your image quality.
I shot a lot on 500mm, as I love a tightly cropped shot (and knowing what my wildlife is thinking) and was pleasantly surprised to see how the sharpness fared. Especially on my birding shots which are a stressful shot at the best of times. (Have wings, will fly.) Although the sharpness and bokeh aren’t as impressive as a brighter prime lens, the distortion managed well, and at 500mm there was still a good blur.
Playing around with the macro shots I thought that the 150-500mm performed similarly at both the widest and longest focal lengths. Both centres were nice and sharp, even though the corners and edges had a bit of an obvious softness. While the sharpness is good at the centre (and is perhaps where I am most focussed on at this level of my photography game), I did learn that this lens requires higher ISOs. All in all, I battled to see the faults in my shots.
