Has anyone here found the need for the hood? it seems kind of useless... is there a hood from another lens that might work/function here?

And how about a carrying/protective case? Do most of you just stick this in your bag, or is there a need for some kind of pearstone/case etc?

No point in the hood, at all.  I worked out the geometry some time back, and the dedicated hood for the 40/2.8 doesn't actually provide any optical benefit, from what I can tell.  It's too shallow to protect even a 14mm prime from flare.  Since it screws onto the extending front element, 'protection' is questionable, too.

The ES-62 hood (for the 50/1.8) with it's 52mm threaded adapter will fit on the 40/2.8.  It's much deeper, and reportedly doesn't vignette, but would likely provide some flare protection.

The 40/2.8 fits nicely in a Lowepro 8x6 case, but I just put it in my bag or more often, my pocket.

Thx for the advice, as always, Neuro.
I ordered my shorty 40 with ES-62 hood; skipped the case for now.

Appreciate it!

Just ordered a shorty, based upon the results i've seen in this thread. The fact that this lens is only £119 also helped! Can't wait for it to arrive!

I picked up the 40mm the last day it was $150 at Best Buy, figuring that I could always return it if I found no use for it.  I only finally got around to using it a few days ago, the return period already behind me.  Fortunately, I'm thrilled with it:


1/4000s | f/9 | ISO400 | 40mm


1/125s | f11 | ISO500 | 40mm

My shoulder bag gets pretty hefty with the 70-200 f4L, 100mm f2.8L, and 24-105mm.  The 40mm just replaced the 24-105mm, and I stitched panoramas out of 40mm shots when I wanted really wide shots (having moved to full frame really makes this more viable):


1/40s | f2.8 | ISO800 | 40mm (six or seven shots merged)

I'm thinking that's a lot of performance for $150 and 4.6oz...

Do new 40mm lenses come with the latest firmware? (I am guessing they do, but haven't found a source to back this up). If so, what number should I look for in the serial number to be sure the lens has the update? Thanks.

I wondered the same thing, as mine has not arrived yet. I downloaded the new firmware just to be sure.
On my camera, you can check the lens firmware version from the menu.

Just seen this.... may help?

Unless you very recently purchased your Canon EF 40mm f/2.8 STM Lens, the answer to this question is probably "Yes". But, Canon Japan has published a serial number key to reliably determine that your EF 40m STM Lens needs the v1.2.0 Firmware Update.
 
If the third digit in the serial number is a 0, 1 or 2, the firmware update is needed:
 
xx0xxxxxxx, xx1xxxxxxx, xx2xxxxxxx
 
Otherwise, firmware version 1.2.0 or later has already been installed in the lens.

Thanks! My third number is a 3 so I think I'm good.

I'm liking this lens more and more. I think it's a more versatile standard lens than the 50mm because the focal length is very 'correct' for FF - the diagonal of FF is 43mm - and the slightly wider angle of view is useful.

In fact I think this will virtually replace my 50mm, I never used that lens below f2 anyway, and the build of the 40 - what there is of it - is much better than the 50 1.4
I agree. Infact I did not buy the 50mm lens with my 5D3 as the 50L was expensive and I did not want to get the 1.8 or 1.4. With the 40mm now I don't think I will get a 50mm lens unless I save up for the 50L and have already got the 24-70 2.8 and the 70-200 2.8 and a sharper looooooong lens...

Oh! Sporgon, I like the picture.

My Pancake turned up the other day. I noticed that it still had the old firmware, and therefore I needed to update to version 1.20.
The update failed numerous times, and I needed to unregister the battery, in order to get the update to install.
All good now though...

Thanks for your compliment rpt.

My 40mm's serial number has 2 as the third digit so I guess it has the original firmware - seems to work just fine.

I've decided that I prefer the 'manual focus by wire' on the 40mm to the focus on non L lenses, you just have to trust somethings happened when you make a small movement !
