Daniel L: Well, may be it's time to let go of my samyang 14mm 2.8... all comes down to price now.

And focusing reliability...

Zoom ring in front of the barrel. Not interested, thank you.

Tony Northrup: This seems almost identical to the Flashpoint XPLOR 600...? Weird that they have two similar wireless monolights. Did they just decide to rebrand a different third-party light?

Btw., transmitter looks very similar to Pixel King Pro...

justmeMN: It would be interesting to see this camera next to an old Canon SL1 /100D. To my eyes, the Pentax in the photos doesn't look very compact.

Mister Joseph: Just swallow the SD card lol

Not all cameras use sd cards. Swallowing CF would be fun :)

Need more action photos with longer focal lengths to prove AF-C capability...

maxnimo: If I needed to shoot extra wide I'd just get a prime lens that's sharper than even the Canon zoom, and at half the price of this one.

Any Canon EF 11 or 12 mm prime lens with autofocus out there?

Even more expensive than Sony FE 70-200mm F2.8 GM OSS. Uff

Zaffa: Ive seen high profile wedding photographers use these at the beach on windy days . I dont understand how they can produce soft light when the light source is so small ?
Im not understanding their benefit over speedlights ? Especially at such a high cost ?
Can someone explain it to me ?
A Yongnuo hss speedlight with a gary fong type dome diffuser vs this bowens portable flash head ? Why spend more ?

Because of much much bigger power?

Mark V already? This must be the most frequently updated camera model ever.

I feel sorry for GoPro and Karma, but that is what it's called wrong time wrong place. Karma should have come 6 months earlier.

RPJG: Another question from a flash newbie:

Why can't flashes stay on for the (relatively short) time needed to high speed sync with focal-plane shutters? Is that not how the bulbs work? Or, overheating maybe?

Priolite Hotsync flashes have duration 1/200 s and it works very well with every shutter speed up to 1/8000 s.

nathantw: So the product video shows the guy carrying the big pack with all the cable equipment. What they didn't show was the guy having to trek back to his car to grab his camera bag. Where's the camera equipment? The way the Slingshot is packed it doesn't look as though there's any room for camera equipment. I guess you need to hire an assistant.

You think some longer slider will be lighter and smaller? Equipment is always large and heavy.

You defintely need to keep doing this videos in the future, very nice!

zakaria: dpr says
2016 is an Olympics year, and..., Canon and Nikon are fully prepared. Both manufacturers launched brand new flagship DSLRs this spring,
......
Then dpr suggested canon for landscape!!
Is there a an Olympic game called/landscape/?
bias in every where.

For example cycling will happen in the countryside, so there is a good opportunity for landscape shots.

Joe Ogiba: Canon should have used UHS-II SDXC slots. The 2000x UHS-II SDXC cards are very reliable and more than fast enough with much lower cost.
http://www.bhphotovideo.com/c/product/1191363-REG/lexar_lsd128crbna2000r_pro_2000x_uhs_2.html

SD cards can be easily mechanically damaged -> not suitable for heavy pro use.

iudex: Nice. That´s exactly what M 4/3 system needs: fast lenses that take advantage of smaller sensor, thus enabling relatively smaller lenses (compare to Nikkor 24mm/1,4 with 620g and 77mm filter thread).
However given the Leica badge it will cost a fortune, so I do not expect big sales. It´s a pitty Oly or Pany do not make such fast lenses (f1,2-1,4) on their own (i.e. cheaper than Leica).

Comparable FF lens is 24/2.8
