Lenses / Re: The New Canon EF-S 24mm f/2.8 STM Pancake

It doesn't look like it protrudes all that far past the mount.  I have to wonder how large that image circle really is because someone's going to try that on a full frame.

This is pretty remarkable, I had considered non-L full frame zooms to be all but dead.  When was the last one they put out?  The non-L 70-300?

You can bend that piece back a couple of times and then you have to replace the barrel.  It's easier to just always leave the hood on and to develop the habit of just setting the focus to past infinity when you stow the lens.

Also worth noting is that for as deep in as you dug, you're not that much further from being able to replace the focus motor and gear train assembly (it's all one part).  The motor burns out and the gears can tear up.



The Ballad of Brave Sir Fifty

Bravely bold Sir Fifty rode forth from Calumet
He was not afraid to die, O brave Sir Fifty!
He was not at all afraid to be killed in nasty ways,
Brave, brave, brave, brave Sir Fifty!

He was not in the least bit scared to filled with fungal growth,
Or to have his aperture fail, and his blades broken;
To have his casing split, and his motor burned away;
And his gears all hacked and mangled, brave Sir Fifty!

His threads smashed in and his barrel torn out
And his switches popped off and his ribbons unplugged
And his electronics scraped and his mount fall off
And his primary--

APS-C is 22.2mm wide which is close to 21.64 but in the wrong direction.  We're also dealing with a machine translation here.

Image height = 21.64mm sounds like APS-C to me, though I sincerely hope I'm wrong.

It looks exactly what I would expect it to look like with every other line merged thusly halving the horizontal resolution.

The fragility of the Canon 50/1.4 focus barrel is mitigated by never taking the hood off it, even when you put it in your bag.  The motor and gears are weak, but at least they're replaceable by laymen.

The real question is if you love the results or not.

Lenses / Re: Help me choose 40 v 50(1.4)
« on: July 08, 2013, 04:44:38 PM »
I have both the 50/1.4 and the 40 on a full frame.  To me the 40 starts to get to the point where it has a bit of that wide angle distortion to it.  It's not much, but it's definitely not a normal.  On a full frame and wide open the vignetting is there for sure.  Manually focusing is definitely more fiddly with the 40 as well due to a slight delay between touch and the result.  Since I manually focus a fair portion of the time this is a big thing to me.  You might not care.

To me the 40 is mostly about size, but it is also the second sharpest piece of glass that I own.  Don't underestimate how sharp it is based upon the size or cost.  It's simply nothing to sneeze at.  Pure raw sharpness won't make your pictures better though.

The main difference to me between the two is halation.  The 50 has it, the 40 does not.  Of course it goes away long before you hit f/2.8 but it's there if you want it and f/1.4 is the on switch.  The 50 has a certain look to it, even beyond just the thinner DoF with some swirly bokeh.

The thin DoF of the 50/1.4 may be too much for you. Bokeh is generally prettier wide open, so having wide open at only f/2.8 is a certain advantage.  With the 50 you can have eyelashes in focus but not the iris or if the head is turned slightly then you have to make sure the closer eye is at least in focus because you're not going to really get both wide open.  You're really playing with fire there and unless you're manually focusing with the high precision focus screen, you're not going to be happy in the end.  But having that much control is truly awesome.

When the 50/1.4 hits the ground while it's extended, the notches in the focus barrel can get warped out of place.  You can just push the plastic back into place which will get you going for a bit, but the real fix is the replace the barrel.  It's not impossible by any means.  Simply slipping the lens into your bag extended enough times is sufficient to damage the barrel, it's really that flimsy.

The barrel is a part that should be reinforced or made of something better than just plastic, but continuous improvement is a concept seemingly lost on Canon.  It's utterly perplexing to me how any company can make the same exact product for decades and never ever tweak it.  It's not like they're making manhole covers or bricks.

With the proper precision matte focusing screen and manual focusing the whole thing is one giant AF point.

Canon EF Prime Lenses / Re: Canon EF 40mm f/2.8 STM "Pancake"
« on: June 23, 2013, 07:37:35 AM »
I discovered that my 5D3 with the 40mm pancake will just fit in a Lowpro Edit 120.  It's a tiny bag, I've found it great for sticking in a larger backpack or taking out with friends to a restaurant for stuff like this:

Heck, a gripped 5DC with a 40 will fit in the little pouch past the bar on a rollercoaster.  That's simply not possible with anything that's not a pancake.

For a lower $/GB cost, the Seagate Momentus XT drives are everything they claim to be.  They're not up to SSD levels, but for most work they're quite good and still head and shoulders above just a straight mechanical drive.

EOS Bodies - For Stills / Re: 5Dc a good option?
« on: March 25, 2013, 11:51:30 AM »
I came from an XTi.  For all of the creature comforts (AF, menus, features) it was pretty much a lateral move.  For you going from one Rebel newer than my old one the only feature you'd be missing out on going to the older camera is the additional integration that the EX II speedlights bring in, but the menus are older looking.

I find the 5D to be on par with my Rebel as far as AF goes.  The adverse lighting conditions that affect the Rebel more or less are the same conditions that affect the 5D.  The 5D, like all other non-Rebel bodies brings in the ability to swap out the focus screen.  I exclusively use the Ee-S precision focusing screen.  That plus MTF lenses and the back button feature and all my focusing needs are met.  The bigger viewfinder is a help too.  If you've survived the 450D's autofocus then you should be just fine on the 5D.  Moving subjects probably track a little better but it's not a huge difference.  Wether that fits your definition of acceptable is entirely your determination.

ISO performance is about one stop (maybe 1 and 1/3) better than my Rebel.  That is to say, if 800 is acceptable on my Rebel then 1600 will be just fine on the 5D.  I'll actually use 3200 on the 5D, but for the most part won't touch 1600 on the Rebel unless I'm desperate.

My lenses are: 50/1.4, 85/1.8, 28-135, 40/2.8  The 50 was my go-to lens on the Rebel.  I've been spending a lot more time with the 85 whenever I'm shooting with strobes ever since moving to FF.  The 40 was purchased as mostly a toy for when I want things the be as compact as possible, but it is amazing when asked.  The 50/1.4 is pure magic, pure absolute glowy magic on a 5D.

My 5D does that on wireless at 1/200 while hooked in with wires I can get away with 1/200.  I'm using a YongNuo with fresh batteries if that matters any.  My XTi will do 1/200 all day long on the wireless and I can push to 1/1250 when wired in.

Lenses / Re: Best Value "Normal" Lens for 6d?

I'm putting in another vote for the 28-135 IS.  You can generally score one second-hand for just a bit over $200 and it will serve most of your general purpose needs better than any other $200ish lens.
