Are any of the following officially discontinued ?
* 50/1.8 II (replaced by STM)
Yes, seems to have been discontinued.
* 135/2.8 SF (no replacement)
Also seems to have fallen off the official lists and is no longer in stock in B&H, so I say it's dead.
* 28/1.8 USM (replaced by 28/2.8 IS)
The 28 1.8 is certainly still available, and I'm curious why you'd think an f/2.8 lens would replace this one? It's still the only low-cost wide(ish) low light lens Canon do.
* 28-135 (replaced by 24-105 IS STM "non L")
This is still listed for sale ($339) by B&H, but Canon's website doesn't list it in the current lineup, which makes me suspect it's being phased out.
But the 24-105 f/3.5-5.6 IS STM at $599 (B&H) is hardly a direct replacement being nearly twice the price. The 28-135 was the first lens I bought to complement my 18-55 on my 500D. I used it a lot, and actually got to quite like it.
* 17-40/4 L (replaced by 16-35/4 L)
Again, the 17-40 offers a lower entry point for a high (L) quality wideangle lens. And it's much lighter than the 16-35 4L IS. Maybe we'll see this around for a little while yet.
* 16-35 / 2.8 L II (replaced by Mk. III)
Still available but again no longer promoted by Canon. The price of the 16-35 2.8 II is halfway between the f/4 and the 2.8 III. I think we'll see this one just fade away as demand for it falls.
* 200/2.8 L II (replaced by 70-200/2.8 II IS)
What? Lol. Totally different lenses. The 200/2.8L is here to stay and I think we'll eventually see a 200/2.8L IS to replace it.
* 28-300 L (no replacement)
Is that because you just don't like it? I happen to know a lot of people (especially videographers) who love being able to take a single lens out with them to cover every eventuality. There's a lot of snobbery about this lens. It's not a lens I'd probably ever want to buy, but I can certainly see the place for it.
* 24-70 / 2.8 L (replaced by Mk. II)
The original 2.8L has been discontinued for a while now.
* 100-400 L (replaced by Mk. II)
Canon kept the Mk 1 on sale for a while because of the significant price hike of the Mark II. The Mk.1 is still available new from B&H for $1300 vs $2000 for the Mk.2 - and this will be another case of the lens being kept on until there's no more demand for it.
* 70-200 / 4 L (replaced by IS)
Another odd suggestion. The non-IS is half the price, lighter and is a superb lens. if you don't need IS why buy the heavier lens? The IS version probably is due for a refresh anyway.
