Canon really does need to update the 50mm 1.4.

Depends on what you mean by update.  I wonder which will generate more revenue - the Sigma 50/1.4 A at $950, or the Canon 50/1.4 at $400?   I think it might be the latter…and the 50/1.8 at $125 will generate more revenue than both. 

I do think Canon will bring out a 50mm IS prime (f/1.8 or f/2) in the relatively near future.  It will be priced lower than Sigma's 50/1.4, and if it has the IQ of the 35/2 IS it will outsell the Sigma 50/1.4A.

I bought the Canon 35 f/2 IS over the sigma and love it. It is compact, light weight, great IQ, and hand-held video is amazingly stable, almost looks tripod mounted sometimes. Far superior to my non-stabilized 16-35 at 35mm handheld.

I've use the Canon 50 f/1.4 for video. Even with a shoulder support, it's tough to keep it steady. I'll buy the Canon 50 IS, if it's at least f/2, but I'm still hoping it will be a 50 f/1.4 IS .

When I read back over TDP's review of the S50A and I think to myself on how to obtain the best focus using a tripod, using the AF from the camera with phase detect focusing is not how I'd do it.

The whole point of the test was to determine the accuracy of the SIR PDAF system with the Sigma 50/1.4 A under controlled conditions, with neither camera nor subject moving.  Should be pretty simple for an AF system with an accurately-focusing lens.   Using Live View would defeat the purpose of the test. 


With Canon lenses mounted on a Canon camera, I've watched it focus on something and lock, then I press the focus button again, it de-focuses and refocuses again. Why can't it just "know" that it has acquired focus and not move the second time?

How does the camera "know" that the subject has not moved?  Having said that, with many subjects, the focus will not change as the PDAF sensor will determine that it is already properly focused.  When the AF does defocus/refocus, that's usually becuase of the characteristics of the subject, for example with a cross-type AF point and a subject having different phase differences in the orthogonal orientations.


The point I was making above is that if you've already focused the lens on X and press the button again, it is doubtful that the lens will end up in exactly the same position as before (and by exact, I mean exact, not some "within half a millimeter.")

Slight variances are one thing - you may see differences with image analysis (MTF/SQF values) that would be too subtle to detect visually.  The OOF shots in the TDP test aren't subtle…the 50A just flat out missed focus on 4/10 shots.

Depends on brightness of scene too. I often focus/re-focus on a subject as I am shooting/ verifying. In good light, my canon lenses either don't change focus distance at all, or very very little, if using single point focus. Most focus changes are probably due to a subtle change in the camera position or change in light quality/contrast on the subject. Defocus/refocus only happens in very low light.

Lenses / Re: Teleconverter advice
« on: April 14, 2014, 10:44:29 AM »
Others have intimated this but I think it needs to be stated forcefully: Canon teleconverters do not tend to fit third party lenses (or even most of Canon's own lenses, especially non-telephoto ones). They have protruding front elements, so the lenses they are attached to must have quite a deep recess at the back to accommodate them. I've not used this Tamron lens, and it's not easy to tell from cross section diagrams how much space there is at the back, but I'd want to be sure others have successfully mated it to Canon extenders before buying one. (You can of course use an extension tube, but that will impact autofocus speed, infinity focus, and possibly image quality).

Third party teleconverters will be more accommodating - I have a Kenko 2x version which fits all lenses I've tried it with - but they will not produce such good results (reflected in the price difference). Nonetheless, they can still be a good choice. It's worth stopping down the aperture a little if you use them, I would say, especially if the lens suffers from distortions/aberrations to begin with.
I've used the Canon 2x III with 12 mm extension tube between it and 50mm 1.4, and the 100mm 2.8L IS macro, and both work quite well for macro. Adding the 2x with extension tube to the 100 mmm macro gives a big boost in magnification.
The 2x converter does result in some loss of sharpness wide open, but for macro the lenses are stopped down quite a bit anyway.

Third Party Manufacturers / Re: Sigma 50mm f/1.4 Art Gets Reviewed
« on: April 06, 2014, 10:47:40 AM »
It's great to know that it exists, and if I ever need one I can get it, but ...

One of the reasons I like primes is the light weight. I love going out with just my Canon 35 f/2 IS on the 5DIII. It is small and light, and it does a damn good job for both photography and video. I am still hoping for a similar lens at 50mm. I don't really want to add another 2 lbs to my bag, but still I'm glad the Sigma exists in case I need one.

I am a Canon fan, obviously since I have heavily invested in their gear ...

... but I definitely want to know if some of my equipment has known design flaws that should be fixed on warranty. I have had to send in two bodies for repair, and I had to return two other bodies for replacement because they did not function properly from new. The two repairs were for issues that were present when I purchased the cameras, and they were fixed on warranty, but I could have easily missed the warranty period.

Post everything you know!

I've never used the C100, but most that have them seem to love them and there's no doubt that the image it makes is very good.  Personally, the ergonomics of the Cx00 series don't fit my shooting style, but others LOVE them and if you're one of those that do like it, you can probably do great things with it.

If low light performance is really good, I'll probably go with the XF200. The C100 low light is supposedly incredibly good, better than my 5DIII, so that is really tempting for me.

Ultimately, I think the best filming package for me would be both the XF200 and the C100, but I really want to keep my 5DIII, not just for stills, but I like the video from it as well and many times I am glad to have both in one package. Don't think I can swing keeping all three right now.

Congrats on Sigma!

Although perhaps not technically super-zooms, Canon's best APS-C travel zooms right now are the  EF-S 18-135mm f/3.5-5.6 IS STM Lens and the Canon EF-S 15-85mm f/3.5-5.6 USM IS (IMHO), and they are not included in the comparison. Both are vastly superior to the Canon 18-200, and probably vastly superior to the Sigma as well.

What are you using for ENG now? What would you get out of the new stuff?
Right now I have a 5D3 and EF lenses (16-35, 24-105, 70-200 2.8, 2x teleconverter, 28 2.8 IS, 35 f/2.0 IS, 50 1.4, 100 2.8 macro), EOS-M with adapter, and 60D, Tokina 50-135 2.8, Tokina 11-16) and a bunch of other gear (audio, tripods , etc).

I do some event coverage, and documentaries. I want to do more of this. I have been thinking of the C100, at least my lenses would be useful. But I'd also like to have something all-in-one, quick to grab, with a GP all around lens. Thinking of the XA20 or XF200, or maybe even just a little Panasonic camcorder. Not sure what to do. C300 is too much $. Don't know much about the new Panasonic GH4 (with the audio add-on) but I suspect this cam is over-hyped.

What do you think?

My 'bread and butter' camera is a Panasonic 2700(P2 VariCam) w/Fuji HA13x4.5.  I bought the C300 mainly just for sit-down interviews and 'artsy b-roll' for feature pieces, but I do work on one show that specifies the C300 as THE camera(The bulk of that show should really be shot with a "real ENG" camera, but a lens like the 17-120 would help).

I've never shot extensively with a 5 for video.  I have two mkII's and a mkIII, but I bought them for stills.  But I have used my mkIII a few times for a third or fourth angle/lock-off.  We've all seen the beautiful images that can be made with it, but I couldn't imagine trying to cover an event with one.  I look at them primarily as a still cam, but if I look at it in the video sense, it should be more of a specialty camera (interviews, specialty shots/b-roll) not a general ENG camera substitute.  You would be much better served with a true camcorder, like the XF200 you mentioned.

I'm worried about low light performance. I've got some of my favorite stuff when there's been almost no light. What do you think of a C100 ? No power zoom, but most everything else is there.

It's not always just about weight.  My ENG camera(lens, battery, VF) is 25-30 lbs and I can shoot a lot longer(and better) than I can with my C300 that clocks in around 10lbs(grip, batt, LCD, and a lens).

That being said, at this point in time, I don't see this lens becoming a part of my arsenal.  Even as ideal as it would be for one of the shows I occasionally work on with the C300(and their rate really doesn't justify it).

My rep said it was probably going to be either 17-110 or 20-120, BUT it's 17-120 T2.95.  And list is $33K.  Not bad…  Less expensive and wider range than the Fuji Cabrio 19-90.  Now we'll just have to see how it stacks up optically.  The Fuji's are excellent.

I'm sure it will be a fantastic lens, but I'd like something smaller, lighter and cheaper, even if it is only 17-70, and the glass is not quite as good. An ENG / Doc lens that indies can afford, and use with no help from a crew ... $5000.   A lens that would transform the C100 into a light weight ENG cam. If I get the C100 I may go for the soon-to-be-released tamron 16-300 3.5 - 6.3 for a GP lens. I'm sure canon could do a better version of the Tamron and add a power zoom. 16-135 f/4 or 16-60 f/2.8 would be awesome.

The 17-120 t/2.95 is US$32,000 and weighs 3 kg !   Put that on a C100 with rig, mic and batteries, and you're heading to 15-20 lbs.  And you'll intimidate a lot of subjects too.  All said, I'd love one, ... and someone to carry it too.

I'm leaning to the XF200 paired with my 5D3 .
I am still considering C100 to pair with 5D3, but I want an all-in-one fast-response package.
The C100 would be great paired to the XF200, but I don't want to give up my 5D3, and can't justify both a C100 and a XF200 right now.

I'm going to save up to rent one for a day ... then live a life of longing for many years :(

I'd be happy with a moderately-decent, powered 24-105 f/2.8 (FF equiv) cinema lens, made to match the C100. Get both for $5000 each, and that would be a great indie doc base kit at $10,000.

Is that really too much to ask?


Unfortunately, probably. The closest thing (26-120mm f2.8 equivalent) weighs 15lbs and costs $90,000.

I'm ok with f/2.8 instead of T/2.0 and I can accept some focus breathing, and a lower grade glass. Whatever they could do for $5000, it doesn't have to be perfect. Make it parfocal though!

If it is a 50mm f/1.4 IS, that would be a hard choice over the 50mm f/1.2.

Not for me. I'll take the IS over 1/3 stop any day. 1.4 is already very shallow and bright

I could go for the 50 1.4 and the 85 1.8 if they have IS.   The big issue is that they are probably 2 to 3 years out for me....

... first they have to get announced (months or years from now), many  months later they may be available at a very high premium, and then 12 to 18 months until the price becomes reasonable.
