To whom it may concern at Canon Inc.,
I am writing this email to express my disappointment with the Canon RT system, particularly the Canon Speedlite 600EX-RT & ST-E3 RT units.
Recently I just purchased a pair of Canon Speedlite 600EX-RT & one ST-E3 RT for my lighting equipment to complement a pair of my Canon 5D mark III & several Canon L lenses.
Prior to that, I was using Speedlite 580EXII, 580EX, 430EX & Phottix Odin radio trigger for most of my off-camera flash photography work.
Just FYI, I decided to sell the above equipment, particularly the Phottix Odin system, to purchase the Canon RT system. Because I thought that using the new Canon RT system with simplified Canon system will help my photography productivity, especially when using off-camera flash.
I found that 600EX-RT & ST-E3 RT system failed to meet my expectations. While there are many improvements compared to the previous generation Speedlite, I found that the Canon RT system has so many limitation that makes it inferior compared to the competitor products, such as Phottix Odin radio trigger system I was using before.
Below are the two major limitations on the Canon RT system that I am really frustrated about:
1. Lack of wireless 2nd curtain sync.
This feature should be easy to be implemented into the Canon RT system. But I am very surprised that Canon decided not to implement 2nd curtain sync in wireless mode. The competitor's products such as Phottix Odin have this feature. I find that the 2nd curtain sync is a very important feature, especially on my photography work. Why would Canon not include this feature, is beyond a common sense & it is unforgivable.
2. Lack of slave zoom control from the transmitter.
Again, this is a feature that the competitor's products like Phottix Odin managed to execute perfectly. Phottix Odin allows the user to change the zoom setting of the slave units from the transmitter.
By having the ability to set the zoom setting of the slave units directly from the transmitter, the user do not required to walk around & manually change the zoom setting on each flash unit. This process will make the photography work much more time-efficient.
I have invested so much money on the Canon DSLR & equipments. I was always happy using the Canon DSLR, but this is the first time I have ever felt that Canon has chosen to become arrogant & give the customer an inferior product / system. Even though I am currently still using pair of my 600EX-RT & ST-E3 RT system for my photography works, I am highly considering to go back to the Phottix Odin system, due to the two major limitations on the Canon RT system I stated above.
However, I still have a little bit of faith in Canon RT system. The Canon RT system has a very great potential if Canon can remove the two major limitations above.
I sincerely hope, or rather HIGHLY DEMAND, that Canon would release a firmware upgrade for the 600EX-RT & ST-E3 RT to add these features:
1. Add wireless 2nd curtain sync.
2. Add slave zoom control in the transmitter unit.
If somehow Canon failed to deliver the firmware updates containing the features above, I am definitely going to GET RID of my Canon RT system and go back to the competitor's product, the Phottix Odin.
