They need some sort of cheap FF kit lens. They just need to remember to make it cheap.
You fixed/variable aperture snobs can go on whinging though; this never is/was about saying it's a "good" lens though good to see Canon's recent releases even down the consumer end (like the EF-S STMs) have great IQ.
This is purely for the people who are convinced to buy one because it comes with a lens that doesn't add a bucketload of cost. Better getting them a body with future possibilities of sales than not getting the body sale at all because the price shot up too much with the L-zoom.
I agree. I would add that being the 5Dc is a nice cheap entry level FF body for those wanting to dip their toe in the FF water, they then get hit with a lot of L-series expensive glass (even second hand lenses). Having a cheap FF zoom alternative to learn about FF would be realy useful and allow people to aspire to the world of L-series.
I doubt this lens would be for the hardened user who already has a supply of L-series, but would be a good introduction or "even walk around and not get robbed" lens.
