Sigma 100-400mm F5-6.3 DG DN OS Contemporary Lens Review

[@FotodioxInc]

Nice review!

[@Gentle_Zephyr]

I wonder why your voice sounds only in the left channel... it might be a good idea to merge audiotrack into mono

[@IddoGenuth]

Hi Kirill - thanks for that comment. You are correct, the music is on both tracks but the audio is on the left only - I will talk to Art about this so it won't happen again on future videos.

The mic is only active for L on stereo

[@LensVid]

Yes as we answered Kirill Eos below we only noticed that the audio is on one track while the music is on both after we posted. It's a mistake and hopefully this will not happen in the future.

Interesting that softness at 400mm 6.3. Some other reviews havent noticed it as much and i dont notice it too. Maybe depends how close the subject is or is it lens variation.

[@IddoGenuth]

We actually tested two copies of this lens as we mentioned. The sharpness was tested at about 12-15m on an A7R IV.

@@IddoGenuth i think close up at 400mm 6.3 is sharper but gets softer, when subject is further away. I noticed you even made this close up test too and it was better. Thanks

@@vads4683 You actually might be on to something here. Still, if you look at our 100-400mm vs. 150-500mm Tamron comparison you can see that from about the same distance (again about 12-15m) the Sigma is significantly sharper. kzbin.info/www/bejne/nWSchoZjasd-qZI

Please, turn the music off when you talk in next video, thanks..

[@LensVid]

We won't turn it off, but we will make sure the voice is a little louder compared to the background music.
