I'll happily use a doubler when I deem it useful, and I am perfectly happy with the results.

Here's one; taken from the top of a tiny boat, bobbing in the waves, very flat, poor light, hand-held. This is a very significant crop (down to about a quarter linear measure); the birdie was a long, long way away, having lunch of another birdie. I didn't have my long lens, and couldn't have controlled it under the circumstances anyway.

Canon 7D, wide open (f/5.6), 70-200 f/2.8 IS II at 200 (so 400mm focal length on the shot), 1/1000, ISO 1600:

I don't like using one, but will for shots where there is no other option to getting closer:

I should mention that this is about an 80% crop.

I'm with the others who don't prefer to use it. HOWEVER, when you need the reach, I've found the newer Canon 2X very effective. If it happens to be on in a less than ideal situation, it can still work. Moving targets are tough with sluggish focus, especially with the 7D.

All taken with Canon 300mm 2.8L IS II plus Canon 2x III extender.

With the slowish AF of the 2x TC, I never expected it to be that good at action (I for one seldom uses it at BIFs).




On my 1DX, it basically works like this - if focus is close to the subject, it locks on and will stay there during AI Servo (as with the race cars coming towards or going away from me). The AF in this case actually works fairly quickly, as compared to when the lens is way off focus. When you look through the viewfinder and everything is very blurry like the focus ring had been turned a good amount, then you half press the shutter button to tell the camera to autofocus, the lens works very slowly, moving the focus slowly until it suddenly is within range of the subject and it'll lock on and it's almost like the lens then wakes up and starts moving quickly again and will stay locked on. Basically, whenever I took the camera down from my eye, I tried not to touch the focus ring so it wouldn't hunt, or if I was in one spot for a while I'd assign a focus preset to help the lens pick up and lock on.

But the IQ from the 2x III with both my 70-200 II and 300 2.8 II was very good, I was impressed with the photos as well as how the combo performed.

Wonderful woodie!!

Do you attribute the color to the 1DX?



No, I do not really. It's all simple Canon stuff: I shoot JPGs only, Standard picture style, and I do not try to mess things up in photoshop, or bring out colours in pp which were not there in reality.

Here's handheld 1DX + 300 f/2.8 IS MkI + 2xTC MkIII.

Main use of my 2x teleconverter I is in combination with my 24/3.5 T/S lens. Fantastic way to get great tilt shift photos on FF with nearly 50 mm FL if fast speed is not needed. Focusing is no issue since tilt shift lenses are MF lenses anyway.

Does anyone user the 2X III with the 300mm F4 or 300mm F4 IS ?
If so, please comment on the combination and post photos if possible.
thanks

Ernie,
the deer shots appear to be the 200 F2 + 2X III
they look nice

did you also have some shots from the 300 F4 IS + 2X ?
that would be 600mm F8

Yikes! I guess I misremembered... I remember now that I haven't yet tried it on the 300 - it was the 1.4x III I've tried on the 300. Here are a few from that combination.

I'm quite sleepy this afternoon, and there's a thunderstorm coming to boot, so I doubt if I'll be getting to trying the 300 + 2x today; but I'll make a note to do so soon...

I used to glue my 2xII to my 300/2.8 IS.

Want to see how bad it is, take a look at this 100% crop

And with 5d3's new firmware, the new 500II + 2x III is a real killer, see this thread

Almost a permanent fixture on my 300 2.8. With the hood @ home & tripod mount removed, this combo has become light enough to take on daily hikes. Photo below is 1/3rd frame (35% of original shot), taken hand held @ ISO 3200 1/320s f6.3 using this combo on a hike yesterday. Even if I had a bigger super tele, I would not taken it with me on this hike.

The 2x TC works pretty well. Not sure who would want to smash it to pieces.

1DMIV, 300 2.8 w2xTCIII = 600mm @ f6.3 1/2000 and iso 320










And with the 70-200II and 2xTCIII

5DII, 70-200II @f5.6 w2xTCIII 400mm, 1/50th and iso 250

There you go, Mark, my favourite SHCIF shot.

I do believe that smart and economy minded wildlife photographers shoot with 300 f/2.8 IS + MkIII TCs.

When we consider the 300 f/2.8 IS based combos performance, versatility, low weight/size and moderate purchase cost, it looks like a peach.

I must be doing something wrong. I've had a 1.4 II for years and am happy with it, generally speaking.... IQ loss is as expected and mostly acceptable.

Some months ago I had a chance to get a 2xIII at a decent price (20% off refurb through CLP) so I did.... I've tried it on the following lenses and my results have been less than stellar..... IOW, unacceptably soft (to me, at least) compared to the 1.4II and certainly the lens alone.... Should I send it back?

70-200 2.8L II
400 5.6L (MF only, of course)
600 F4L I
800 5.6L (MF only)



A 2x TC should work well with your listed glass, at least with the last two lenses. At 100% view, a 2x TC shot might deceptively look less sharp per pixel than a 1.4x TC or naked lens shot. However, when you equalize the images (IOW upres the 1.4x or naked lens shots), the one taken with a doubler has more details.

IME, soft 2x TC shots with a big white are normally caused by misfocus, camera shake or subject motion. Can you post a sample of your 2x shots?

While a 1.4x literally lives on my 500 virtually all the time, every once in a while it'll come off in favor of the 2x. It does a wonderful job...


A head-on BIF is a tough AF job even for a naked lens. Well done, Chris!
