IMG_0190I was looking for a 1.4x teleconverter for my canon lenses.
Finally, the Kenko C-AF 1.4x MC4 was very interesting. Due to it’s construction you can use it with almost every EF lens from Canon.

So, the plan was to extend my lenses to 70mm f/2.0 (EF 50mm f/1.4), 140mm f/4.0 (EF 100mm f/2.8) and 280mm f/4.0 (EF 200mm f/2.8L).

After I read a few promising reviews I ordered this little thing.

I’ve done a few tests with it at home and I’m not really surprised about the results. First, it is unexpected good at high focal length (>100mm). But I can’t expect a perfect universal converter for about 110€… with the EF 50mm f/1.4 is it not usable for me (blurry…), the EF 100mm f/2.8 looks much better and with the EF 200mm @ 280mm the image looks good enough for me, so I’ll try it for deeper sky next time!

At least I’ve a converter for my 200mm L-lens 😀

I used a remote shutter controller to avoid shaking and focused carefully in LiveView mode at 10x zoom.
