Canon 1.4 extender

I would like another more range while taking migrating birds in the marsh...would an extender to team with a canon 70-200 L be worth the investment?

The extender not only gives your lens an effective longer focal length, it also has some down sides. The extender will also multiply any defects the lens may have by the same 1.4 amount. Additionally, it will decrease your effective f-stop by the 1.4 amount as well.
If you can live with the downside of the extender, great. That will save a bit of money. If that turns out to be an issue, then a longer lens might be in order.

Which version of the 70-200? A series III 1.4 will work better with the f/2.8 versions of the zoom. But, the extension is only 40% or to 280mm at the max, really not that much of an oomph .... If your have an f/4 zoom, consider changing over to the 100-400L II if in your price range. That would be the oomph you're looking for when birding.

Yes, MIII is the best one for the lenses and works like a charm and is 100% compatible with your Canon 70-200mm f 4 and f2.8.

I use a canon 2.0 III extender with my 70-200 f/2.8 L and am very pleased with the results. While it only gives you up to 400 mm it has been okay for me. Good luck in whatever you choose.

Yes, worth the investment - but must be using in good light to maximize quality.
Version III extender only valuable if used with a version II lens - and then only for maximum AF performance.

I was hoping you'd post a reply. I remember those beautiful shots you posted a couple of days ago of planes(?) They were taken with a long lens and a Canon 2.0 TC.

They were, yes, with a 2x behind a 500mm prime. The experiments I've observed with a 70-200 f/2.8L is that doubling this lens can be as good as the 100-400 for image quality. But, those experiments tend to be images of lines are charts and don't include tracking birds in flight. The 100-400L II provides the option of extending out to 560mm on an ever growing number of EOS bodies. I have a stream of posts now prepared of real-world results with various extenders and lenses. Stay tuned at a UHH near you
For our OP, before buying, you should address the earlier question and comments about using an EF 70-200 F/2.8 IS II (or now available III). If you have a version that is a good candidate, try renting both the 1.4x and 2x and make a hands-on experiment and analyze the resulting images to determine how best to address your need.

To have a “reach” that would be a satisfactory improvement, I’m skeptical that you would delighted with a TC. 1.4 x 200 = 280 mm with a loss of 1 f-stop. You probably could buy. 300mm lens for about the same as a 300 mm lens. Best answer is to buy the Canon 100-400 mk2 if you can afford it. I shot a Canon kit 300mm for 2 years before I got a Sigma 150-500mm. Then used that for 4 years until I got the 100-400 mk2. Then I got the 1.4 TC. I’ll probably stay with this rig for a long time. Need time the save and allow technology advance for a very high ISO, high frame rate cropped or full sensor camera body in my price range.

I use the 1.4 and the 2x on my 70-200 and am happy with the results. I think it would be worth the investment. If you order from BnH you get 30 days to return it if you aren't satisfied.

If you decide to go that way, rarely used (as new) Canon extenders are readily available, and the 1.4x MKII can typically be had for $175-$200. The MKIII versions are a bit more. They appear to depreciate at a much higher rate than lenses and are often very lightly used, so a good candidate to purchase used, especially if you have doubts as to your usage. I regularly use a MKII 1.4x with my 135 f2L and the results are excellent (actually sharper than my 70-200 f2.8L at 200mm without an extender).

What kind of photos do you shoot makes some difference. Landscape, portraits could work well with 1.4 or 2x TC and you 200mm lens. Bird or wildlife would require more reach.

I look forward to your results. My own limited experience with 1.4x with the 100-400 II lens indicated a significant loss in IQ at 400mm max. aperature. So much so that it wasn't any better than the 400 cropped. I am told the extenders work much better with some lenses (esp. primes) than others and many pros seem to use them so my results may have been flawed. I did use a tripod and static subject matter and manual focus for the test.
