Harpin tähän aiheeseen jo säikeessä:

Mutta jatketaampas täällä, kun otsikkokin kohdallaan.
Olen yritellyt etsiskellä tietoa kuukkelilla, mutta aika hintsusti sitä vielä löytyy. Erityisesti testejä/katsauksia kaipaisin.
Yonguo:lla on myynnissä uuteen tuoteperheeseen liittyvät laitteet:
1) Yongnuo YN600EX-RT (Salama) (hinta n. 130€)
2) YONGNUO YN-E3-RT (Keskitetty ohjainyksikkö) (hinta n. 80€)
3) Yongnuo YNE3-RX (Vastaanotin muiden salamien liittämiseski Canon:n 2.4 GHz radiotielle) (hinta n. 50€)
YN600EX-RT ja YN-E3-RT ovat yhteensopivia Canonin vastaavien kanssa (Canon 2.4 GHz Radio System), mutta eivät Yongnuo:n vanhojen kanssa.
YNE3-RX:llä saa vanhoja ja muidenkin valmistajien salamoita sopimaan 600EX radiotielle.
(Epätäsmällisyyksien välttämisesksi en kääntänyt seuraavia lainauksia)
(Note: They are not compatible with other Yongnuo products (like the ever popular YN622 triggers). These new products use a radio signal that is simply not compatible with the older products’ (non-radio) technology. Interestingly, it seems that Yongnuo is going to introduce receivers that will allow any speedlites (and possibly also strobes) to receive this radio signal! For more info check page:

From reviews of YN600EX-RT and YONGNUO YN-E3-RT:
1) The only feature I felt was missing is just the possibility to set the flash’s zoom remotely with the trigger. Not a big deal, but if you like to change zoom settings frequently this may be an issue for you.
2) GN declared by Yongnuo is 60 but my tests indicate that the power is the same as the older Yongnuo YN560-II, whose declared GN is 58.
3) Recycle times are also very fast; at full power even slightly faster than the 3 seconds (declared by Yongnuo)
4) Flash and trigger are easy and fast to pair, the connection is stable and reliable and you have no issues triggering the flash from a distance, even through walls or in bright light. But all of this is true only while THERE IS a connection… Unfortunately the connection between flash and trigger broke a few times quite randomly during usage and would not be automatically reestablished. This may sound worse than it really was and in fact, with one exception, the issue arose only right after swapping batteries in the flash. I then found out that the radio channel got changed by itself, thing that can be adjusted in seconds.
5) I upgraded the firmware in the trigger (the upgrading process is quite erratic and in fact I was not able to upgrade the flash in spite of several attempts) and since then I did not experience the issue (4) again. if you buy the products now, with the most recent firmware, you may never have an issue with the radio connection.
By the way, be aware that the firmware upgrade currently works only on Windows.
6) The flash several times randomly showing the overheating error message, straight after turning on the unit; turning it off and then on again immediately solves the problem. A newer firmware may have solved this issue.
7) The whole point of this system is to do away with external receivers and their associated cables and batteries and mounting points. Less stuff to go wrong. In exchange for that, yes, you are buying into a closed system.
Vastaan tulleita kysymyksiä/väitteitä:
a) Reliability with a flash or trigger as a master (Canon vs. Yn, or at least Yn with Yn.
b) What's the longest distance?
c) How many objects can be in between?
d) How do they work very near ground level?
e) How reliable does the auto channel selection work on areas with high radio noise?
f) With a 100 flashes, how many fail to transmit on say 3 slaves?
g) How is the hot shoe fit? I have head the Yongnuo is a little smaller and moves slightly and have heard sometimes this cause fire issues (iether the 600-EX-RT or the E3-RT
h) How is the connection stability between the YN-E3-RT and the 600s. The other complaint I have heard is that the E3-RT seems to drop connection over time and if you turn on and off the -E3-RT it will resync.
i) Chinese Menus. I have seen some who have shown the menus and fonts getting all screwy - half chinese or english overlayed.
j) Yongnuo is "cooler" (värilämpötilaltaan) or more "blue" compared to Canon
k) You can’t leave the batteries in when not in use because they will drain.
