At this point my affliction is more GMS than GAS. Back in November I acquired a white Canon EOS M with a third party EF to EF-M adapter. No lens focal length shorter than 60mm would focus at infinity. I had no EF-M lenses and only that one adapter so I couldn't really tell if the problem was the camera or the adapter although I strongly suspected the adapter. I guessed it was a bit longer than it should be.
Right after Christmas, I traded my EOS 7D and some lenses at Ray Supply for a new EOS M3, kit lens and electronic viewfinder. This let me confirm that the original EOS M functioned well and the problem was the adapter. A different adapter, this time a Fotodiox Pro, works well with all lenses on both cameras.
My latest GMS episode was the other day when I sold my 70-300mm DO zoom lens which is a bit soft and doesn't perform well on crop sensor bodies image quality wise. With some of the proceeds, I've ordered the EF-S 55-250mm f/4-5.6 STM lens to use with the 24 megapixel EOS M3.
The two EOS M series bodies with the kit lens, 24mm pancake and 55-250mm zoom lens will constitute a nice little setup for lots of occasions. My full frame 5D Mark III, 24-105mm L series zoom and 40mm pancake lenses will be used for more serious events and occasions. I still have the problem of processing RAW files from the M3 on my MacBook Air but I've a Windows computer I can use if I need to.
I hadn't used the older EOS M for much of anything and decided to try it out with the kit lens for a sunset last evening. One thing the newer M3 is bad at is bracketing exposures. It's much slower than the M. I've been used to the 5DIII at over 5 frames a second and the M at around 3 frames a second. The M3 brackets at about a frame a second.
Here are the three bracketed files from a sunset scene last evening along with the finished product.
|24mm, f/5.6, 1/250 sec., ISO 200, 0 EV|
|24mm, f/5.6, 1/750 sec., ISO 200, -1 1/2 EV|
|24mm, f/5.6, 1/90 sec., ISO 200, +1 1/2 EV|
