Canon Introduces New EF 50MM F/1.8 STM Lens

Re: Canon Says Same Optical Formula

Crosswind said:
You're right, sir. Well, the optics are the same - that doesn't mean it's delivering the same optical performance. I have a feeling that some people here are kind of disappointed with Canon's new 50. I can't see why. Is it because of the missing IS or focus window (lol)... or is it because of STM-only?

For me, the main drawback of the 50/1.8 II is/was the build quality - but not the "plastic fantastic" characteristic, but the extended barrel when focusing.

This has been mentioned before, but this makes the lens *very* fragile. No problem if you're just shooting your aunt's birthday indoors, but if it's for street or outdoors you're bound to bang into something sooner or later - and there go your $125 (but you can keep the $35 lens cap :-)).

Disclaimer: I'm sure lotsa people will be just fine with this lens as STM or USM probably is a matter of preference and how important FTM is to you.

But I'm sorry, folks are getting 2 more blades, curved blades, STM, increased max magnification -- all for no increase in price. Photographers should say thank you to Canon for that.

Thank you, Yongnuo!

Does anybody seriously believe Canon gracing us with this constant price and update just now is a coincidence?

Fascinating. Those side by sides look more like three nifty fifties and less like two nifty fifties and a pancake. I recognize the physical height is similar, but now I see the front element baffle... it really looks more like a more efficiently packed 50 f/1.8 II than a standalone design.

Now we know that it's the same optical formula, this shouldn't surprise me (but it still kind of does).

Found a video that shows the focus noise (or lack of!),

It's hard to determine how much noise it makes because there's so much background noise (intentional to hide the motor sound?). It's obviously quieter than the mkII, but if you listen closely it makes the 40mm STM, Robocop-like noise while focusing. A bit off topic, but do all STM lenses make that noise? How about the 24mm STM?

I was able to track down the originator of the video to this post here at Reddit:

He said he's open to questions if anyone had any.

I wonder if this lens will fit any older hoods. Occasionally there's the rare compatibility and I do have 3-4 random Canon hoods laying around.

The ES-68 bayonet mount hood is unique to this lens. No other Canon hood will fit. None of them share the same 68mm internal dimension.

Well there is the the EW-68A and EW-68B, but those are clip-on hoods and will not fit the bayonet hood mount of the 50mm 1.8 STM. (clip-on hoods barely fit the lenses they were designed for) ;)

And no other 3rd party hood? Ok, that's the last straw (until a lens hood clone is there) for me, I'm definitely not going to pay $35 for a 35ct piece of plastic :-\ and a lens hood is simply required when shooting outdoors for protection from flare and damage.

The 55-250 atm is truly silent and very, very fast, at least on the wide end. The 24 is supposed to be the same as the 40 which is not as fast or silent.
It's a shame, a really wanted the 50 to get the faster version of stm. I'll still get it though, unless the af is inaccurate.
