Upgrading from sony to canon

[wayno]

Yeah, ive used 18mm on full frame once and it was perfect , 18 on crop was wayy to long

I did not realise quite how bad the corners were, would use at f11/16 be good enough for landscape do you think?

Shooting at f/11 to f/16 you should get reasonable corners using the 5DII.  Pixel-peeping you will notice some softness, but it is still good enough for printing.
If ultra-wide angle landscapes are your thing, then, in the longer term you may be better off looking at getting a 17mm prime.

I must have a good copy of the 17-40 but I get exceptional sharpness across the whole image at F8. 17 is not quite as stunning but a bit longer and it's great.

same, mine's sharp at f/5.6 at most focal lengths and pin sharp at f/8. higher than f/11 and diffraction starts to set in and everything softens up.

Are you using it on a full frame or crop body?  The soft corners only really become an issue with full frame.

Hey i'm finnally making the move from sony to canon what i've been using is:

Sony A33
18-55 3.5-5.6
70-200 f4.0
35 f1.8

I'm upgrading to:
5d mkii
17-40 f4.0
50 1.4
135 f2.0
Battery grip
16gb Cf card
spare Battery

My predicament is weather to buy a 430ex ii with a couple triggers or a Tameron 28-75 2.8
I mostly shoot longboarding, landscapes a little bit of portraiture low-light events, day time events and quite a lot of video, but I really want to experiment with flash but not sure I want to lose the focal range capability for video or lowlight shooting, recommendations?

Thanks, Harvey

Good decision. Whilst Sony has better sensors, Canon has some of the best Lenses around. Especially they're prime selection.

The glass wsa the main reason along with video that im moving to canon
also, om the length issue I was going to go for a sigma 120-300 2.8 OS in the distant future

Ironically, I have been thinking Sony is looking better and better, especially with the finally-NEX-I-can-live-with NEX6 and A99.  Sony is bound to release a scaled-down full frame body to compete with 6D and D600, and the price is likely going to be much nicer.

And they still have weak lens selection for both lineups. The NEX line barely has 10 lenses, and that says nothing of whether they are any good. Same is true of A-mount, especially if we are talking for full-frame; the cheap primes just really aren't there. You have to go third-party in many cases.

Although they did have nice cheap crop primes, a £120 RRP 35mm 1.8 and a £100 RRp 50mm 1.8 but only worked on crop were loverly lenses although they were extremely plasticity and had terrible polygonal apertures :s
