In regards to pre-ordering the EOS R I am on the fence. The biggest deal breaker for me on this camera is the AA filter. Had they removed it I would have replaced my 5D4 with this. At this point sometimes I think I will pre-order and then I think let me wait for a high megapixel variant. I know for sure it is purely GAS nothing more that that
One thing not sure if anyone has noted only the following will ship in late October
EOS R initial price of $2299 (available late October)
Mount Adapter EF-EOS R initial price of $99.99 (available late October)
Control Ring Mount Adapter EF-EOS R initial price of $199.99 (available late October)
RF 50mm F1.2 L USM initial price of $2299 (available late October)
Speedlite EL-100 initial price of $199.99 (available late October)
The below two are shipping in December
RF 28-70mm F2 L USM initial price of $2999 (available December)
RF 24-105mm F4 L IS USM initial price of $1099 (available December)
The adapter with drop in filters will ship only in Feb 2019
So Unless one has $2300 for EOS R and another $2300 for the RF 50mm there is no other RF lenses shipping with the EOS R in late October. If not spending money on the RF 50mm one will be limited to the two adapters and EF lenses. One thing I am not sure is that if anyone orders the EOS R + 24-105 kit the whole thing will ship only in December or the camera will ship in late October and then the lens in December. Bare minimum one need to spend $2400 to use only with EF lenses and $2500 to use EF lenses and have the control ring.
