35 L II and the 50 f1.8 IS
Could also be update of 135L, but 35L is in more need IMO.
+1 again These 35 and 50 mm lenses are direly needed to upgrade Canon's lens line-up.
I'm in agreement here. These are both holes that need quick plugging, particularly considering that the Sigma is ending up in a lot of bags, and, for others of us, the new 35mm f/2 IS is actually in many ways superior to the current 35L. It is my most recent addition.
Count me in for wanting the new 50mm. I don't have an AF 50mm in my kit right now because I was never blown away by the (non L) 50mm choices. I have owned and then sold two copies each of the 50mm f/1.8 and 1.4. I have never bought the 50L because of both its own shortcomings and high price. I make do with some vintage options (Takumar and Helios), and really enjoy those lenses. But for a lot of work AF is really needed.
Although I never use AF, I am also waiting for a great modern fast 50mm. The 50L is too expensive for me, and the 50 1.4 and 50 1.8 are too weak in term of build quality and handling IMO. The Zeiss 50mm 1.4 wide apertures performance aren't good enough for the price, although stopped down, there's nothing to complain about. The 55mm, although spectacular, is really out of my budget. The Sigma 50 1.4 seems to be the best value in term of sharpness, but the handling isn't great and the focus ring is too stiff for pleasant MF. The best option would be the Voigtländer 58mm 1.4, but it doesn't exist in EF mount. I personally can't justify buying a 500$ lens in the wrong mount, especially if the mount isn't a m42.
I hope rumors are true and 2014 is the year of the 50mm : Canon IS 50mm + Samyang 50mm 1.2 + Sigma Art 50mm 1.4 (although this one seems to be more of a speculation than a rumor).
Look into the Zeiss 50 f2, although far from the 1.2 aperture, but you mentioned the 50 f1.8. The Zeiss f2 is superb and really makes the Zeiss 1.4 look really bad... I love the 1:2 macro as a bonus to crop your portraits as close as you want with fantastic sharpness at f2. love the 50 perspective compared to a 100mm macro for example.
Thanks for the suggestion. It is true that the Zeiss 50mm f2 looks astonishing; the sharpness is ridiculous, like the build quality, colors, micro-contrast and, I guess, the reselling values (30 years old CZ 50mm 1.4 still sell at 450-550$ on eBay!). Also, the 1:2 macro looks really nice; you can even have 1,86:1 easily with extension tubes. However, at 1283 USD (source: B&H), it is pretty expensive for such a "slow" prime.
Is it worth it? I have no doubt! However, it is still a lot of money.
Personally, I am waiting for 2014 before buying anything, in case there is a "game-changer" such as the Sigma Art 35mm (which is even better than the Zeiss 35mm 1.4 for half the price!). Still, I am saving money for if this doesn't happen (1283 USD to be precise!)
