Just got a Sony 1.4 TC to put on my Sony 200-600mm, not had a chance to test it yet as its been raining all week and today when its sunny I'm stuck indoors. I read good things about it and hoping its not like Nikon ones where some work and some won't micro af in.

Works perfectly on my 200-600mm.

It seems to work well but not tried it on anything serious as it was raining since I got it and now I'm stuck in with a chest infection.

Sorry about that Iain.
It’s my observation that the key to getting TCs to perform optimally is very much down to best lighting. The loss of a stop is significant when the lighting is less than ideal. In retrospect I suspect all TCs are the same in this limitation, but with the Sony, despite the IQ being little affected with the TC, I’ve been aware that the tc/600mm combo quality is more reliant on lighting.

I would agree with that Eric. I got out yesterday but the light here was patchy. The ones I got in good light were fine with a little sharpening.

x1.4 works very well for me and the loss of a stop is not serious. Yes weather has kept my camera mostly out of use & since Christmas with a dose of Covid!

At Last a good day to try the TC. Not much about so here is a Blue Tit taken at 600mm +tc.

Is that the Nikkor 14 mrk. 3 ??... I have a KENKO 1.4 ,using on some shorter focal lengths incl. 24-70..35-70...70-200 f4.0..pcE 85 , not sure if I should look to the nikkor tc., but there is a 2nd hander for sale for reasonable money..how do you find focusing with it , is there noticable focus-lag ?

No, I'm on Sony now.

You can only fit the Nikkor TC14 E III to compatible lenses, specifically, it won't work with the 24-70, 35-70 or the PC E 85. It will work with the 70-200 f4. You can check compatibility here Nikon LCC .

As Geoff said, be careful about compatibility. I used the 14 III with the 500mm exclusively primarily because that’s when I wanted maximum reach.
It is an exceptionally good match for the longer lenses with no loss of functionality apart from 1 stop of light loss. But I have to say when I had a Kenko 1.4 with it was perfectly acceptable. It was my observation that any loss of performance was more to do with the 1.4x magnification requiring faster shutter speeds ….and my failure to accept that, when hand holding.

I have never found that TCs work very well on zoom lens till now as the Sony one works great.

That’s a good point. I also found that tc’s tended to amplify hidden limitations in zooms that weren’t obvious when using the lens on its own.
I recall doing a test comparing a straight 300mm (max zoom) image cropped to match one using a 1.4x Kenko on the 300mm. The cropped image was better! When the same tc was used on my 500mm prime the image lost nothing! It’s very much down to the quality of the lens they are used on.
The Sony 200 - 600 is an excellent lens. ( the 100-400 is even better) I have wondered if a cropped 400mm + 1.4tc would match the 600mm +1.4?
The 100-400 is a lot lighter and I maybe need to redo that test….it could reduce the weight of the bag.

That would be an interesting test. As you say the 100-400mm is a lot lighter.

Will wait for good weather. Of course with any cropping test one has to be mindful of the iso being used.
Cropping a high iso noisey image not only enlarges the subject but it enhances the background noise appearance as well.
It’s one of my gripes with the 40MP sensors. Yes they give more detail when the light is right, but beware cropping them as a substitute for long lenses when the iso is high. They seem to exaggerate the noise more than a 25mp sensor.

I agree. That’s why out of the A9ii and the A7riii I find the A9 is the camera I prefer. It’s also got the stacked sensor as well which helps.

Having had a variety of cameras and lenses and t.c’s over the years from canon,Nikon, kenko, sigma I found that some are good and some most definetly are not .
These days I’m on olympus and there 1.4t.c works quiet well even fitted to my apeture limited 100-400 lens BUT caveat emptor I’m now on third copy of one the first two giving differing i.q this one does work quiet well even at F9 which is wide open with the big lens .. but it does give nearly 1200 mm of reach in full frame terms and thanks to olympus I.b.I.s and I.s ability is hand holdable

Yes that’s very true. In fact it’s also true about lenses as well as tc’s. I recall trying 3 versions of a Nikon f2.8 (expensive!) zoom lens just after digital took off, before I got one that didn’t give chromatic aberrations (fringing) in high contrast areas. The local dealer was a bit bemused and probably thought I was being a bit anal, but when you are paying £1500 for a lens (20 years ago!) it needs to be worth it.
The Olympus set up would seem to be ideal for birding.

Thank you all for your thoughts, it is appreciated, and yes, some investigating shows that Nikon and TC`s are a world of their own..
