When I switched to Canon cameras from Nikon in 1995 the one thing that I missed from my old F4S cameras and my old SB25 flash units was the accuracy and reliability of the Nikon TTL flash. Canon, with all of their promises for the EOS1N and Speedlite 540EZ combination just couldn’t quite match what I had left behind. I have no idea how Nikon managed to get their off-the-film-plane metering to be so good but it was very good indeed.
Coincidentally, it was about this time that I started to use high quality battery powered lights. The Lumedynes that I took delivery of in 1996 changed my professional life and TTL flash became something that I used when I absolutely had to.
Fast forward to 1998 and the arrival of the first decent digital cameras we had (the Kodak DCS520/Canon D2000) and flash took a big backward step. There was no ‘film plane’ for the cameras to meter from and we had to dig out old Vivitar and Metz flash units with old fashioned auto settings just to get somewhere near where we needed to be with our exposures. Canon introduced the 380EX flash which helped but it was basic and relatively low powered with no swivel head and working with them wasn’t a patch on shooting with the pre-digital Canons, let alone the film based Nikons.
Time passed and with every new camera and every new flash unit things got a tiny bit better but I have never felt as comfortable or as confident with TTL flash on digital Canons as I did with film Nikons. There were work-arounds – I used flash exposure compensation at the same time as reviewing the LCD screen and using some pretty good guesswork which, when used with RAW files, meant that we were always able to do the job but it was never without effort in the way that you used to be able to shoot flash with the far less forgiving transparency film.
That was until now. Strike up the band. Hang out the bunting. Canon have, in my opinion, finally done it. They have a camera and flash combination that handles TTL as well as anything that I’ve ever used professionally. A few weeks and a few jobs with the new Speedlite 600EX II RT on my EOS5D MkIV cameras have convinced me that twenty plus years of being unsure with on-camera flash are over. Congratulations to everyone at Canon involved in this evolutionary process – well done.
Footnote: I have owned and used 220EX, 380EX, 420EX, 430 EX II, 430 EX III RT, 540EZ, 550EX, 580EX II, 600 EX RT Speedlites before arriving at the 600 EX II RT. I’ve had the ST-E2 and ST-E3 RT transmitters and any number of external flash packs and light modifiers. The joys of being a photographer – no wonder so many of colleagues swear by ambient light.
