Animal Zoo Antwerpen Belgium Part 2

Another nice series Vince. I especially like the Orangutans. The look like a typical old couple sitting together. 8)

 

Re: Thanks for your reply

Vince,

I have the TC-14 and the TC-17 that I use with my 70-200VR and 300 2.8. I like the 1.7 just fine, but the 1.4 is nearly as sharp as the lens by itself. I think that it is well worth it.

Another option is to look at the 300 f4. It is a very good lens, and can also be used with the 1.4 TC. That would get you out to 420mm at f5.6. Harris (Backdoctor) gets some great shots with this latter combo.

 

Vince,

It is true that you get the 1.5 or 2.0 crop factor, and that does make the image a larger percentage of your cam sensor, but it doesn't make a lens 1.5 or 2.0 times longer. I try to look at a 300mm lens as a 300mm lens, but understand that with a full frame cam, the resulting image would be a smaller percentage of the total frame than a DSLR with these crop factors.

OTOH, a TC will actually increase the optical length of the lens, so you do get 300 / 420 / 510 / 600mm with a 300mm lens and the 1.4, 1.7, and 2.0 TC's, along with the associated DOF characteristics that one would expect with lenses of these lengths.

Hope this answered your question.
