I think it depends if you want to add other lenses in the future, d6400 is better noise and AF wise but if you are going to stay with 18-135 then a6000 sould be enough. On the other hand a6400 ...

I believe there is not any reliable adapter between sone e and nikon f mounts especially if you need full AF functionality.

200-500 + tc will give you better quality I would avoid reflex lens,

Great test, I have a tendency to place more value to users tests and opinions than professional reviewers where the numbers are a bit meaningless. With your test it is easy to replicate it and ...

In your test I can see a significant difference between the two lenses. Maybe the difference is getting more obvious with long distance tests.

lol, I am not cherry picking reviews as I not quoted any review but only users experience, You also acknowledge that PF is a little sharper in the centre and that just the fact it is little sharper ...

200-500 is known to have quite a lot of bad copies. also another doubious statement from that review: -Excellent VR, consistent sharp images hand held down to 1/50 sec. and this is simply not true ...

Believe me no much difference in the center unless you have a bad copy of 200-500. Unfortunately "trusted" websites make general statements based on one, often bad copy of the lens. The tests of ...

Sigma S is very heavy and do you really want to adapt it to Sony? I like experimenting with setups but to me it does not make much sense unless you already have Sigma lens on Canon body.

1/30 s handheld is amazing, was it lens oss only or combined with camera stabilization?

Very nice, is it handheld?

You got it wrong, D500 vs D850 does not give you longer focal lenght, only narrower field of view (which is a drawback). They have almost the same pixel density so no difference in focal lenght, ...

I know tht Nikon and Canon 400mm f 2.8 are usable with 2x tc so the same should apply to Sony 400mm. Sony 200-600mm +1.4 tc should be usable with A9 and rather not with A7r III as it has much ...

Great AF performance here I think d500 would lose tracking here. BTW is a7r III AF good enough with this lens or is A9 AF much better?

It is copy variance in my opinion, according to tests the difference at 600mm is rather small.

Hi, Raw seems reasonably sharp to me, especially with the teleconverter. Your jpeg seem to be oversharpened for me. I did some minor adjustment in Lightroom (not much needed) and cleaned noise and ...

thank you, yes d500 now and some on d7500 earlier

I use that combo a lot, see examples here: https://www.flickr.com/photos/162376953@N04/

This is a great threat concerning 500mm pf quality, please do not add photos from other lenses or unnecessary negative comments that discourage ppl from adding photos, especially if you do not own ...

Great quality even taking into account your great postprocessing skills Would you mind posting this shot without any postprocessing to show 500mm+ tc 1.7 capabilty?
