I like most of their videos but I do wish they put a bit more thought into substance vs humor.+1
I enjoy watching DR TV reviews, not because they are in-dept (they aren't) but they bring a different view point for the smaller things e.g. the palcement of light indicator on the Sigma USB dock, none of the other reviews I've read/seen covered that ... also Kai makes the videos very enjoyable. I prefer to follow/watch about 5 reviewers as listed below:
3. Dave Dugdale's youtube channel
4. thecamerastore tv youtube channel
5. digitalrevtv youtube channel
In addition I also, follow/watch at least dozen other reviewers, infrequently.
Great list! I'm not sure about 3. Sometime he's insights are good but others comes off preachy. Also I don't know if he's presenting himself as a Pro or semi pro. Although it could just be some people come present better on camera. I'm not dissing him but its hit and miss
To add to your (youtube) list I also look at:
Matt Granger - (He's a Nikon guy in Canon Clothes... but his views have help me with my 70-200 purchase)
Jared Polin - If you like Kai, this guy must be his US counterpart with substance.
Dan (Learningcameras.com) - Nice and clear.
Indy Mogul - Top for Indie DSLR film makers! If your into that stuff.
Thanks for the suggestions ... I do watch Matt Granger & Dan (I prefer Dan's reviews) ... I only watch Jared Polin's un-boxing videos, and his famous sniff test as well as his "Fro-Knows-Photo" intro
... but I am not very fond of Jared's reviews, coz I feel there are several inaccuracies in his reviews. I used to follow Camerlabs, but lately he seems to have gone self centric about his trips and stuff - they probably appeal to his followers, but I'm not too keen, I'd like to see him get back to posting more tutorials and Canon/Nikon/Sony gear reviews (but I think he prefers the Micro-Four thirds these days).
I only watch Kai when I don't want to get too deep and just want to unwind with some humor about camera gear ... nothing "scientific or educational".
I've never watched Indy Mogul ... but after having read your post, I've just glanced through his youtube channel ... sounds very good to me ... thanks for the useful suggestion.
