This is one potential reason why I've stayed away from their software.  If they can't characterize the lenses correctly, does it affect their software products?

Perhaps it would be worth trying the same experiment with a Sigma 35 in a store to see if all Sigma lenses behave like this...

Either way, it looks like Sigma failed to reverse-engineer how the Canon firmware/software behaves exactly.  At least with Sigma, there is a chance that they'd release new firmware/software so that you can update it via the USB dock...

Nobody mentioned it - I'm quite sure they will block 3rd party lenses (eg a lens needs to identify itself correctly).
Even the Sigma USB dock does not really help. I have the 35 Art lens and you can set only 3 focus distances (~0.30 m, ~0.60m, infinity). While the focus is perfect @ f/1.4 for these distances, it is quite off between 0.60m (+14 in the USB Dock tool) and infinity (+3 in the tool). No way to correct that at the moment. Sigma still has issues here.

+1.  I wouldn't be surprised if a change like this would lead to compatibility issues with 3rd party lenses.  It would be one thing if 3rd party lenses would function as they had before and the canon lenses gained increased accuracy, etc, but it would be another if the 3rd party lenses are bricked.  As much as people complain about Canon bodies not accepting 3rd party batteries after a firmware update, not being able to use 3rd party lenses would be much worse.  Not so much an issue for MF lenses only (i.e. Samyang), but it would be a large threat to Sigma/Tamron.  Even if Sigma were able to provide updated firmware after a few months, the damage will be done.  People may blame Canon for breaking compatibility with 3rd party lenses, but a lot fewer people would be willing to take the risk of buying 3rd party lenses again...

What do you mean by "losing a lot of picture at the edges"?  Mechanical vignetting?  If so, what is the max aperture of your 50?

Or are you talking about being limited by the fixed magnification ratio, which is determined by the focal lengths of the two lenses that you are using?  If so, then a dedicated macro lens makes a lot of sense.  You can use different magnification ratios up to 1:1, which gives you more freedom for framing and then use the reverse lens technique for more specialized shots.  Either that or pick up the MP-E 65.   ;D

I don't think that Canon should replace the 50mm f/1.4 with a f/1.8 IS. The reason being the Sigma Art lenses.
I would hazard a guess that a new Canon 50mm f/1.8 IS would be a similar price to the new Sigma 50mm f/1.4. That would be an interesting choice.

I wouldn't be surprised if the IS goes into a f/1.8.  A lens at f/1.4 with IS is too close to the L, unless they made a f/1.2L with IS, but Canon's strategy seems to IS their non-L lenses, and maximum apertures are reserved for their L counterparts (i.e. at 24mm and 35mm).  With the Sigma 50 coming in larger than the previous version, a small and compact 50 f/1.8 IS would be great for those that value low weight and discretion while the 50L II would have to offer more than the S50.

I'd buy a 20mm f1.8 (or 2.0) L if it was on par with the 24L & 35L

I'd be interested in that too, which would allow much to ditch the 16-35 II.

You know it's slow in Canon land when people start making lists like this to pass the time!

Only if you ignore the DR threads.  ::)

To be fair, though, the two lenses mentioned here are both rumors.  The actual lenses and their respective apertures haven't been announced yet. 

As for the three non-L IS versions that have been announced, two of them kept the same aperture as their predecessors (24/2.8 and 35/2).  Both jumped in filter size (52mm to 58mm and 67mm, respectively), although Canon doesn't seem to be very concerned with filter sizes any more. 

Only the 28mm dropped from 1.8 to 2.8, which is a shame because a 1.8 with IS would have been a great "normal" lens on crop and would have made a real distinction between the new 24 and 28.  But Canon has kept the original 28/1.8 thus far, so apparently they weren't ready to kill that particular darling just yet, despite the sense it would have made.  Now they have two 28s in the lineup, which sell for about the same amount new, with the only spec differences being aperture and IS. 

Trying to make sense out of Canon lineup decisions is maddening.  For instance, why start putting IS in your wide angles rather than your telephotos???

The 28 f/2.8 IS replaced the 28 f/2.8 non-IS.  The 28 f/1.8 is still being sold; the 28 f/2.8 non-IS is not.

Also agree with Ellen that Canon is leaving the option open to release a fast 28mm lens.  The non-L IS lenses are 35 f/2, 28 f/2.8 and 24 f/2.8.  The Ls go 50 f/1.2, 35 f/1.4 and 24 f/1.4.  A 28 f/1.4 L would slot nicely between the 35 and 24Ls.  Although I'm not sure if there is a sufficiently large market for 28mm primes anymore.  It seems like the 24s are a lot more popular than the 28s.

Reviews / Re: Review: EOS M System
« on: January 10, 2014, 12:21:12 AM »
hello everyone,

kinda curious. I have my M with 2.0.2 firmware verison and Samyang 8mm f/3.5 fisheye. However, I couldn't use this 8mm on M. Shutter button wouldn't work and the touch shutter woudn't either.

I changed mode from Av to Tv to M and P. None of them worked. Neither Intelligence mode nor Video worked.

Anyone got a clue?

Thanks all.

Did you try Custom Function IV (screen 7) to set Release shutter w/o lens = 1 (Enable)?

Lenses / Re: How 'bout primes
« on: January 06, 2014, 02:52:14 PM »
Nothing like being forced to be idle to ignite Gear Aquisition Syndrome (GAS)!

With the 24-70 II and 70-200 II as good as they are, the advantages that primes have over zooms have been reduced, but the advantages can still be significant.  One thing you had mentioned is using the 50 f/1.4 for low light.  I prefer fast primes to the zooms indoors, so the question is whether or not the 50 f/1.4 satisfies your requirements.  If you need something wider a bit of time, then a fast 35 might be the correct complement.  For portraiture, a fast 85 might work well.  Some people swear by the 135L, by I find it less "essential" when you have access to the 70-200 II.

Really, what it comes down to is which photographic discipline do you want to improve in.  Want to take better indoor event candids:  look at a 35.  Want to take better portraits:  look at a 85 or 135.  Want to get into macro or at least have a higher max mag than what your current lenses offer:  look at a 100 macro.  The key is to have a defined scenario for each of your lenses.  The scenarios will dictate which lens you use when and will maximize the utility of your gear funds.  In your case, it might make more sense to save for the 300mm lens that you rent...

EOS-M / Re: Question Sir " Filter for EF-M Lens"
« on: January 06, 2014, 01:09:43 PM »
Because you already have the filters, I'd try a couple test shots to see if they degrade image quality or not.  That will tell you whether or not your film-era filteras are good enough or not.  If you can't see any difference, then there is little point in buying more expensive filters.

In my case, I have filters on all my filterable EF lenses, but none on the M because of their relatively low price (22 and 18-55).  If I were to get the 11-22, then I'd probably get a filter for that because the replacement cost is a bit higher at $400.

No hoods for me either.  Just as small a package as possible.

OK, looks OK, just OK, but why does Canon still offer 30+ models of P&S cameras? I thought this segment was largely dead, taken over by iPhones.  I should think six models would be plenty. Just don't get it.

It's still a large market, albeit shrinking.  Plus a lot of those on the page are the previous models.  A new model comes out and pushes down the price of the lower model.  The consumer can choose to buy the latest and greatest and pay the higher price or choose something that does 90% of the job for a bit less money.  Either way, Canon makes a sale and makes money.  As long as each product offering is profitable, Canon is better off offering more choices that would cater to a wider audience.

Congratulations on your family's addition!

I would hold off until you get the 6D kit and trying your existing lenses with it before replacing the 50 f/1.8.  The 50L does not perform that well at/near its minimum focal distance (if you AFMA at MFD, you'll be off significantly at more "normal" shooting distances).  See if the 50 f/1.8 will satisfy your requirements first before upgrading to the 50L.

None of the lenses you listed have very high max magnification (135L is best at 0.19x and the others range from 0.11 to 0.15x), so you'll be missing detail shots.  Newborns are small, so I'd suggest getting the 100L first.  It will give you the detail shots that you will not be able to get with the rest of your kit.  The IS also gives it more flexiblity for general photography and portraiture.

Lenses / Re: Should I go for the 85mm F1.2L II USM ?
« on: January 06, 2014, 08:03:35 AM »
If the 85L II is what you have your sights on, go for it.  The 85L II is designed as a portrait lens, and for that purpose, it works well.  It's harder to justify if the 85L II would be your only lens at that focal length and if you need for other scenarios, but when you have the 70-200 II too, the 85L II will be used mostly for portraiture while the 70-200 can be used for sports, etc.

The way I use a fisheye now is more of a non-essential. It's to have it there when i need it. But i feel that I lug it around as a paper weight more often then not. that's why I ruled out the 14mm. It's just a tad bit too wide for everyday practical use as well as astrophotography and landscapes, given the large price tag.

Does anyone have any experience  with the canon 24mm? I really like a fast lens and don't mind that it's fixed focal length. When shooting stars pretty much anything at night more light is always a plus.

as for the Zeiss and the Samyang and maybe Tilt/Shift lenses, I have no experience with Manual focus for more practice uses and everyday stuff.. Is it easy to pick up?

The 24L II is a fine lens, good for just about everything except for astrophotography due to the coma.  To avoid the coma, people stop it down to f/2.8 to f/4.  You don't want to use it wide open for astro.  The 24-70 II is said to have less coma than the 24L II at f/2.8.

If you use a tripod/LV for much of your landscape work, manual focus and tilt/shift will not be hard to pick up.  If you don't use the movements, the TS-Es are about the best EF lenses at their focal lengths.  However the movements give you so much more capability to correct perspective and tilting the focal plane.
