EF 1.4x teleconverter

[Scotty72]

Last week, I bought the Canon 70-200 2.8 IS II / Canon 1.4 TC combo.

It is fantastic. Yes, you lose a stop but I can't fault the IQ.

Here are a few shots I have taken with the two together.

Scotty

#1 - @98mm (including 1.4 magnification) (lens set to 70mm)


#2 @280mm (lens set to 200mm)


#3 @280 (200mm)


#4 @280mm (200mm)

i dont own the particular lens you specified. I did try the 1.4x TC II on a 70-200mm f/2.8 II in the shop and the IQ seemed quite good. I have used the 1.4TC on 300mm f/2.8 and 135mm f/2.0 with good results, but with this good quality glass it is generally known the TC does not bring quality down much. With lesser glass the loss will be more noticable, but I think for the cost and versatility the teleconverter is a good deal.

Scotty72 WOW!!!!!
I'm impressed with the image quality, and the reach.

If other reports on this thread are accurate I should expect similar results with my f4L.

Can you have a look at the metadata and tell me what apertures these pics were taken at?

Thanks

Will do when I get home. But, the exif data is there if you right click.

Hi All, I'm jumping in late here and this is a question rather than suggestion or opinion. I have a EF 24-105mm f/4L IS USM (using it with 7d and 400d) and wonder how that would perform with the 1.4. I've never used an extender before, I really like the idea of getting a little more reach on what is pretty much my
workhorse lens. Thanks, Mike

It won't perform at all; it is not compatible with that lens.

The two cannot be physically attached.

True that!

Think about waiting for the new MkIII TC's coming out around January - supposed to be a big improvement in sharpness over the current MkII models.

Otherwise, there should be a few MkII's being sold second hand just after..

I have heard the 2x converter isn't as good as the 1.4x converter. Has anyone else found this. In sharpness I think?

Oh I don't know about that
kenko 2x teleconverter, sigma 120-300mm f2.8 and canon 5dmark 2

The performance of the Canon teleconverters is well-known, and uncontroversial.

Given a suitable lens, they have excellent image quality. Sharpness is not in question. The only things you must consider are the things that apply to ALL teleconverters: (1) loss of light - 1 stop in this case, (2) loss of contrast (mild for the 1.4, more noticable with a 2.0), (3) slow focus (significant for a 1.4, very, very significant with a 2.0), and (4) less pleasant bokeh (very subtle with the 1.4, and still not obvious even with a 2.0, but there just the same). These four factors are things you just have to accept if you want a teleconverter. These are things that all converters do, even the best ones.

Summary: yes, worth having, but don't expect miracles.

Hi Nigel, I use my Kenko 1.4 with my 70-200 F2.8, it's a great combo, as Scotty72 has mentioned and shown, out to 280mm i believe if me calculations are correct.

Have you got it yet, and what have you found ???
