I can see a 16-35 f/4L IS in my bag for christmas

I believe Canon should introduce a 16-35 f/2.8L III, a 16-35 f/4L IS and a 14-24 f/2.8L. Then we would be OK as far as UWA FF zooms are concerned (before asking for an IS version of 16-35 2.8L with IS that is)
Is that too much to ask ?
P.S OK feel free to add other variations, price ranges, APS-C UWA zoom ranges, etc... After all it is a rumor site
And what would be the speculated prices for:
- 16-35 f/2.8 MKIII = ?
- 16-35 f/4 IS = ?
- 14-24 f/2.8 = ?
Who give up the 16-35 f/2.8 MKII for a 16-35 f/4 IS?
Wait a second, did someone just compare camera lenses to car pistons?!?!
Yep, that is the kind of "reasoning" we have to try to dispel sometimes.
Not the best analogy maybe, but if you try to read what I said rather than trying to take one sentence out of context, you might understand. THERE IS METAL TO METAL CONTACT. Your reasoning is, there is not enough metal to metal contact to cause any "appreciable" wear. I say, there is certainly metal to metal contact that causes wear, when people rush to change lenses...as if they are changing wheels on an F1 racecar. Oops, there's another car analogy! My whole point was, the mount is far from indestructible, and care should be taken when changing lenses. If you are just wanting to argue, go ahead, but you have to admit, I have a point.
Hold on, let me post under another name to egg this on...oh wait, I'm above that.
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.
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.
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).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.
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 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.
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.
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.
