Finally tethering on the 650D, not sure why it was missed out.

I wonder if it's possible to upgrade from 4.x to 6 when released? I think I might miss 5 out - seems a bit late in the day to pay for this version now?

Gesture: Yes, Canon SHOULD be continually upgrading EOS-M firmware.

And quite why they didn't transfer the Live View firmware improvements from the M over to the 650D which has the same sensor, is just plain lazy.

Kinematic Digit: I was doing several overlays of the MTF charts and of course, Canon only publishes theoretical values so this must be taken with a grain of salt.

But based on what I've cross referenced, this lens might actually be a hidden gem.

Wide Open the new lens has better contrast than the 70-200 F/2.8 IS L II and the 70-300L

Tele the 55-250 is about on par with the 70-200 F/2.8 IS L II and almost identical to the 70-300L

This new lens falls off sooner at the edge in the overlay, but if you stretch the overlay to match (to measure the fall off performance at the edges), it actually matches the L glass in optical performance almost identically (some cases better)

I expect what you can produce on full frame with one of the L zooms will be tough to find worse with this one. Almost makes me question my L glass collection.

yabokkie, what do you mean exactly?

You could argue using FF lenses on a crop sensor means you get the best a lens has to offer i.e on crop the edges of an image are actually utilising a more central region of a FF lens because the FF imaging circle is of course bigger.

Kinematic, I really hope you are right. I have really been toying with buying the F4L IS, but concerned 200mm wasn't long enough, and the 70-300L I felt spending £1100+ on a variable aperture extending lens was a bit rude also.

I really hope this is a decent performer because it bridges the gap in focal length nicely, saving £000's of pounds is always good when this is only a hobby. And another point but less so, is I wouldn't feel self-conscious with say the kids at the zoo with a whopping white lens!!

My only criteria is it must perform pretty well optically and with quick AF as I like to take motorsport shots. Mustn't be built like a toy either, so the plastic mount doesn't bode well?

Probably expecting too much for a kit lens? In which case they need a middle quality tele EF-S to sit between the kit and L lenses. Like a 15-85 style lens but of course tele focal length - 55 or 70-250.

Treeshade: Panny is not trying to make old 20/1.7 owner buy the new one; they just want to change the "year" label from 2009 to 2013 so it sounds good on the new GX2 package. (And almost every m4/3 owner who did some research would have bought the old one already.)

I agree. Panny to me is fundamentally an electronics company, that whole industry is built around the whole shiny shiny this is new concept. Perhaps I'm being overly cynical? But I doubt a traditional camera/lens company would be making a new mk2 version of a well received lens after only 3/4 years?

On Best Digital Cameras for Kids article (141 comments in total)

Bought an S31 for one of mine on their 5th birthday. Very simple to use and bright colour options (pink!) are perfect.

Oldest (8) wants a camera now and not too sure if to go for a rugged one or not? Had a look at an XP60 as mentioned here, really unresponsive shutter and focussing, whereas an Olympus TG-630 was miles better.

However a Canon SX240 might be more useful due to massive zoom range and I guess better IQ?? Just as long as it's not dropped I guess!?

Karl Gnter Wnsch: Their measurements are so badly screwed - the 100mm f/2 USM lens better than the 100mm f/2.8L IS USM - there is something fishy going on here, and it stinks mighty badly!
I can only see one reason in their published data: They seem to take all aperture settings into account which a lens offers - and at f/22 (the maximum the 100mm f/2 can close it's aperture to) the diffraction of the sensor isn't as bad as on the 100mm f/2.8L IS USM where the lens can close to f/32.
So these guys basically are morons who have no clue what they do and should be barred from further producing this overload of measurement garbage! Please DPreview - do yourself a favor and drop them from your portfolio of partners, you're better off without them!

Haha, tell it like it is!! :)

I have been manually looking at some of the lens and looking at the sharpness maps (at apertures appropriate to the lens), doing it this way would you consider their results usably accurate?

Why didn't they test the EF-S 15-85mm lens?

Also, is it exactly the same sensor and LPOF arrangement as that found in the 650D? Be good if these results translated directly across.

Reactive: Had the zoom range been just a bit more practical for day-to-day use... let's say 18-70mm... this would have been the perfect 'always-on' lens. Considering that a 50mm f1.8 is so tiny and light, surely 70mm at f1.8 is possible without the lens becoming too large or expensive? But then I know nothing about the physics of lenses!

Agree with Thorbard, I have a 15-85mm lens, the 2 can not be compared as very different purposes. I am considering an indoor fast prime to compliment the 15-85, perhaps a Sigma 30 1.4, but it might not be wide enough at times and I don't want multiple yet similar FL primes. Therefore this new 1.8 zoom is perfect. Fast enough and flexible enough to do indoor great when speedlites are not practical.

This would have worked much better with the original sky I think, on this image now it just accentuates the fact the light is coming from the wrong direction.

Image aside, thank you for the tutorial.

yabokkie: I have a problem with the word "super-fast". it isn't. this lens is an equivalent of 24.6-53.7mm f/2.8 on Nikon and Sony APS-Cs. it's just as fast as an f/2.8 zoom on 35mm format.

p.s., it's a 25.8-56.4mm f/2.9 on Canon APS-Cs.
the real range and f-number may be different that we will likely have a slightly narrower range and less fast zoom.

Yabokkie, "when" I win the lottery let me buy you a 1.8 lens, a FF body and a crop body - I think this is the only way you will learn that 1.8 is 1.8 with respect to exposure! And easily worth a couple of grand for the peace and quite compared to a few mil that the lotto will yield!! ;)

simon65: The samples look great. I can't see any problems there at all.

The million dollar question is, are Canon going to launch some smaller lenses to go with this new pocket DSLR? Just three would do. But without them the pocket DSLR concept lacks coherence.

I wouldn't say truth hurts at all, but you have a slight point, a few fast primes would be great.
Those native lenses I've listed cover typical ranges for photo work. Only thing missing is perhaps a tele, although the 55-250mm for the money is a steal really. But you have to consider how realistic is it to care too much about size when your using a tele lens. IMO, a mute point.
I use a 650D and 15-85 combo as a versatile daily option, I spent a long time deliberating m4/3 and also Nex systems as possible alternatives. I personally felt that unless the size savings allowed true pocketablity, then if I was carrying a bag then as long as it wasn't a full frame monster, in all honesty it didn't make too much difference on platform. A good compact is the way forward for pocketability. And that is the point really, your still going to need a bag with m4/3s coupled to a good lens. So its hardly the holy grail of compact shooting. So swings and roundabouts really, but EF-S is far from a joke.

EF-S - 17-55, 15-85 and 10-22 are all a joke? I thought they were all very well considered lenses or am I wrong? Also isnt the 60mm macro supposed to be good...
True there are no EF-S primes other than the macro but surely its no issue to just use an EF prime in your budget to suit? - The 40mm pancake is small and very good and very cheap to boot.
I guess if they could develop the EF-M 22mm into an EF-S that would be about the only thing missing from an EF-S line up point of view - as a native small fast 35mm equiv would be a great all around lens, esp if it had IS and F2(+) for low light usage.

On Samsung launches Galaxy S4 superphone post (108 comments in total)

Will it still feel like a cheap plastic piece of junk?- I expect so.
I was gobsmacked when I first picked up an S3 after all the hype. Perhaps the consumers of today have no need for build quality and things of a tactile nature.
Happy with my decision to go for an HTC One, although had the Xperia Z had a more ergonomic feel to it I would probably have plumped for that, very solid.

So you've got your phone on you to take a picture (maybe an unexpected moment hence no camera), but you also have a tripod on you! Really? That seems an unlikely combination to have on your person!

Whats wrong with say a lump of blu-tac for a few pence!!

On Canon Powershot G15 Preview preview (246 comments in total)

I currently shoot with a G10 and have never once felt that I needed a flip-out screen. I don't consider that a loss and certainly this new lens looks a welcome improvement. But, without a bigger sensor my desire to upgrade hasn't been satisfied, shame.

I assume they will still maintain the 'X' range of G-Series? So here's to hoping the 'G2X' or whatever it will be called, combines this fast lens with it's bigger sensor.
