anyone use this combo: 70-200mm f/4L w/ 1.4 teleconverter?(10d)

[richie_boone]

I was thinking about buying a 1.4 teleconverter with above combination and wanted to

know if anyone had any luck and was satisfied. Samples would be great!

Thank you.

I have used this combo a lot and it's very nice. Do not know what kind of photos do u wanna do with that... in any case with a 1.6x sensor that combo make a quite long lens and u must be very careful with shutter speed. With the TC your lens will becomes an F/5.6 and it could be a bit slow if you wanna use it for action, especially in low light conditions. <a href="http://www.photo.net/photo/3111074">Here just a sample</a>.

It seems nobody does...

I use this fairly frequently and it works just fine. I can't give you an exhaustive f-stop by

f-stop review, but I've used the combination under a range of conditions and have never

been disappointed by image quality (at least, not anything that was the fault of the lens).

With an extension tube between converter and lens, it works surprisingly well for

moderate macro shots as well (on <A HREF="http://biology.ucr.edu/personal/

MACphotos/mammals/deermouse.html">this page</a>, all of the deer mouse photos

except the lower left were with the 70-200/4 +1.4X).

I have this combo, and I'm very happy with it! Used first on a 10D, and now on a 20D. I never think twice about inserting the 1.4x between the lens and body; the deterioration in quality is for all (my) intents and purposes, nonexistent.

I've used it also and found it rather awkward: flares too easy (especially sunsets) way

too long and rather slow at F5.6. The EF 200 2.8L USM is faster, sharper, more flare

resistant and handles much better.

I have also used this combo, works fine. Michele, just a comment, the 1.6x is just a FOV crop, it does not make a lens longer. It is impossible to change the focal length of a given lens just by putting a sensor behind it.

[richie_boone]

Cool! Thanks for the info-I might have to get the 1,4 now!

Only I wish I had The 70-200mm f/2.8L instead of the F/4L.

 

thanks again!

[andrew robertson]

Yes, until I got the 300 f/4L IS. It worked quite well.

I have this combo and I like it on a tripod. I agree with Puppy Face's comments about it's size and speed. But I am happy with it overall. Here is an example wide open...

I use the 2.8L version of that lens with a 1.4x teleconverter. I used to have a 10D, and

mounted there it gave impressive reach - having the ability to zoom back out a little is a

nice touch for some telephoto applications like motorsports where sometimes that

300mm on your 1.6x camera is too tight to capture the action of a scene. In terms of

deterioration from the TC, all I can say is you'll never notice it unless you scour your

images looking for it, and if you don't tell, they'll never know. The 1.4 is a great piece of

kit and combined to your camera crop magnification will really give your long lenses a

boost. 5.6 max aperture may be limiting for some applications, but your 10D will handle

itself very well at ISO400 and in bright to even moderately low light you'll be fine... I'm

linking to a photo that isn't particularly good, but was taken on a very overcast, borderline

dark day with the 70-200/2.8+TC1.4 combination at ISO400, probably f/5.6. I panned

along with the car, and focused in on his number as it would be easiest for the AF to lock

onto with it's high contrast. It's a bit pixelated from web compression, but I think you'll be

very satisfied with that gear combination.

Eamon,

 

Perhaps you missed my post above...

 

"where sometimes that 300mm on your 1.6x camera"

 

I don't see how you get to 300mm. 200mm x 1.4 = 280mm.

 

"The 1.4 is a great piece of kit and combined to your camera crop magnification will really give your long lenses a boost.

 

The 1.6x factor is a field of view crop, there is no "magnification". Your 200mm lens is still 200mm. With the converter (1.4) it becomes 280mm. The 10D crops the image in comparison to 35mm film.

[erol_a.]

well yes, to be technical, and perhaps to dabble in semantics. In effect, however, you've got a frame that is closer to full that it would have been on the 35mm camera we weigh our focal length values on. I admit my phrasing continues the misinformation of the technical aspect, but in effect, that lens (which yes, is still a 200mm) is giving you what 200 x 1.6, 1.5, 1.3, whatever our crop factor is, in terms of 35mm equivalence, which is what most of us think in terms of.
