Gary,
I tried to reply directly to you, but was getting the invalid email address
reply, so not sure if you got my reply. So I decided to post it here:
< George,
I know from past conversations and postings on the EOS list that you own
and use the Kenko Pro 300 teleconverters. I am considering the purchase of
the Canon 300 f4 non IS lens or a Kenko 2x to attach to my 80 - 200 2.8L.
Obviously, the Kenko is much cheaper than the 300, but will the quality
compare? My professional work is done completely in Photoshop so I'm
wondering if the cheaper approach is better, at least for now. What is your
impression of the 2x compared to the 1.4x?
Thanks,
Gary >>
Gary,
Well, I had exactly the same question before I got my Kenko TCs and my 300/4
lens. Which to get? Easy answer - all of them. But if you have to chose -
nothing beats the ease and convenience of a TC. I'd get a 1.4x first. Almost
no loss on quality with Pro level lenses like Canon 80-200L 2.8 and you only
lose 1 stop. 2x is a bit softer than 1.4x and you lose 2 stops. But it's
still very good. I'd say 1.4x is on par with Canon brand TC. With 2x Kenko
you'll see softness in corners, but center is still good. Now, nothing beats
a prime lens, so 300/4 is still best choice for quality. I went with a Tokina
300/4 ATX (now discontinued, but you may find it at around $400 at places
like Adorama ). which has slower and nosier AF motor, but optics are great.
I'm not sure about it's compatibility with newer bodies like 3 or Elan 7
though - I use 1n and old Elan and RT bodies. Canon is obviously a great
choice, but more money.
Hope this helps. If you have more questions - let me know.
George
