I'm also thinking about getting a TSN 99. A big upgrade for me. I am very grateful for information from an independent user. I also like your videos. Keep it up !! THX

I really enjoy the footage and thanks for sharing this comparison video. Big LIKE!!! I'm a new friend here from Singapore. Stay connected. Happy Birding and Happy New Year!!!👍🔔

The 2x is not a good choice - it introduces distortion. You should compare 600/f4 with r7 (1.6x magnification) and 1.4x adapter and stop down slightly. I have seen this arrangement outperforming the Kowa. And the r7 is $1500. What I saw elsewhere is that the 600f4 outperforms the kowa cropped and is way better when you take into account image stabilisation. see kzfaq.info/get/bejne/qKiKqsun1JmtiqM.html at about 4:19

And film it in portrait mode

Hi Federico, very nice to see another digiscoper👍😀…are you from Spain? I am also a digiscoper from Holland… have a look at my digiscoping channel and it is nice to share information about digiscoping. Hoping your adapters will arrive soon…waiting for your next video. Kind regards Ron.

What camo cover are you using for the howa?

Ciao Federico, ho visto il tuo video e questi spotting scope per la naturalistica mi tentano molto. Qui su YT c'è #Ron Schuddeboom Digiscoping che è un esperto e fa dei video da paura. Aspetto la recensione c con l'adattatore per la fotocamera

got it, the sports journalists with big canons were all stupid. They should get a spotting scope and hold their phone😂
