Field Review - canon 400mm 5.6 + Kenko 1.4X pro 300 DGX Combo
« on: February 12, 2014, 11:03:36 PM »
Friends,
It is impossible to have a single bird photographer who doesn't wish for longer lens or the longest possible reach within budget. Frankly speaking, I'm also a budget photographer and hence always look for a cheaper way to photography (Read 'Bird Photography') coz it costs a lot.
This time I was thinking of using a 1.4 tc with my canon 40D+ canon 400mm 5.6 combo ( 400x1.4x1.6= 896mm). As canon Tc would not auto-focus and report exposure + aperture correctly, I thought of using a Kenko Tc which would report and auto-focus on my 40D @ f8.

Keep in mind that I'm sharing 'my personal experience' with the Kenko 1.4x pro 300 dgx Teleconverter.

My work:-
Just sharing my flickr link for the sake of viewing and reading exif data if you like.  :)

I'm going to share my experiences with Kenko 1.4x pro 300 DGX Teleconverter in general and my experiences using it mounted on a Canon 40D + Canon 400mm 5.6L.

Technical Details of the Product :-

Test Details:-
Few month ago, I've tested this Kenko tc casually on a Canon 100-400mm 5.6L+ Canon 550D/ 60D, owned by friend of mine and on my Canon300mm f4 L (non-IS) which I was using with Canon 1.4xTc ii and found that Kenko gives better focusing speed and accurate focus locking when used with Canon 300mm f4 than Canon 100-400mm 5.6L.
Image Quality is also superb (almost Identical with Canon 1.4xTc ii) when used with 300mm prime.
With Kenko, 100-400mm suffers IQ and focus locking . Kenko 1.4x pro 300 DGX is faster than Canon 1.4 Tc ii while using with Canon 300mm f4.

But on 2nd Feb'14, I thought to give Canon 40D + Canon 400mm 5.6L + Kenko 1.4x pro 300 combo a hard field test. So I borrowed the Kenko Tc from a friend and used it in a bird shootout  @ Gajoldoba Wetland, WB. My setting was 40D with Lens + 1.4 Tc @ f8 and to surprise it auto-focused!!

The shooting condition was purely HandHeld on a small fishing boat and my experience is mixed one. We started nearly @ 8.30 in the morning and the Sun was covered due to heavy mist.
In poor light condition the lens +tc combo hunts and failed to lock focus but the bare lens focuses quickly.In good light (Sunny) the lens + tc combo hunts little and confirms focus but not too quick as the bare lens do.
In my opinion it is not suitable to use the Tc (though it auto-focuses) if you are keen on getting some action shot.
If the subject is static and you are mounted on tripod then OK.The tc takes sharp image with canon 400mm 5.6, means you loose little IQ. Same result is obtained regarding focus on a 550D.

Pros & Cons:-
.Very good when used with primes having aperture f4 or faster.
.Unlike Canon Tcs, Kenko Tc can be fitted to almost every lens.
.Not so good when used with lenses having max.aperture 5.6. But you can live with it. I never used it with any other zoom except 100-400mm 5.6L.

Build Quality:-
Build quality is OK but I like the feel and handling of Canon Tc most over Kenko.

Value for Money:-
I must admit that it's a value for money Tc coz without breaking your bank you can have a tc which gives almost identical IQ when used with f4 or faster lenses.

Comparison:-
I tested my 400mm 5.6L coupled with Canon 1.4tc ii (manual focus) and it produced amazingly sharp and great looking images with superb contrast & colour. But Kenko gave a little lesser.
Kenko gave me superb  focus locking speed on 300mm f4. Must say it's better than canon 1.4 tc ii in this regard.

Summary:-
A good value for money Tc and produces almost identical IQ if coupled with f4 or faster lenses.But on Canon 400 5.6 it needs good bright light to lock focus and to be accurate.

Recommendation:-
Recommended for f4 or faster lenses.
You can be happy with the result when shooting static subject (bird) using it with Canon 400mm 5.6L. Best result can be obtained out of this combo if you use a tripod (I guess). Some BIF can be made if the bird is big enough.

Result:-
The image below is almost 50% crop and minimum PP is done so that you can judge the result of this combo.

Biplab, nice work with the combo.
Once in a while,if you are lucky and light is very good, you can even capture BIF shots with this combo. I was successful only once in Mysore. I got a Pelican BIF shot. It was posted about 2 weeks back here...

Thank you all..... :)

Yeah Prabir Da, if light is good it can do good job.
I remember that shot you posted in JJMPF also.
But it was a big bird like pelican.I tried my luck on Red-crested Pochard taking-off and still blaming myself.

No. I own the 100-400. But have tried it on 400 5.6 of a friend and also on Sigma 150-500 (totally not recommended lol).
