At Twycross Zoo With A Teleconverter

At Twycross Zoo with a Teleconverter

One of the things in my camera bag I don’t get to use too often is my Nikon TC-17E II teleconverter, so our planned trip to Twycross Zoo on a sunny April day seemed to me the perfect opportunity – given the relative separation of the animals and people – to get some extended use of it.
"I attached the teleconverter to my Nikon 70 – 200mm f/2.8 lens, giving me an effective focal range of around 120 – 340 mm….."

I attached the teleconverter to my Nikon 70 – 200mm f/2.8 lens, giving me an effective focal range of around 120 – 340 mm.

Not bad for around £300, though it does come with penalty of reducing your minimum aperture to around f/4.5; not really a problem, though, given that the light was pretty good that day.

My main intent was to get some shots of the new baby elephant, which can be seen in the mini-gallery I’ve put up below. But, we took several hours to get a good tour of the zoo, and I’ve also included a number of my favourite images from the various enclosures.

The one thing I did notice was that some of the images – see the close-up of the one I took of one the Ring-tailed Lemur‘s face – was that the teleconverter did introduce some unusual bokeh, though this was only really noticeable where I had fairly uniform backgrounds.

To me, it looks almost like streaks on the screen, and was evident on all my similar images. Whilst I’ve noticed a slight ‘swirl’ on the Nikkor 105 mm micro, it’s nothing as obvious as this. Anyone else noticed an effect like this? I’d love to hear your comments if you have or, even better, if you’ve any tips for reducing the effect….

In any case, enjoy the images; comments on the cuteness of the animals, and especially the baby elephant, will always be well-received!

All the best,
