Lenses / Re: Did Canon Leak the EF 11-24mm f/4L?
« on: November 12, 2014, 05:57:28 PM »

Interesting sidebar question:  what's the last EF lens Canon rolled out that didn't deliver the goods?  I am not referring to lenses that were unreasonably priced -- I am asking: what's the last time Canon put out an EF lens that wasn't clearly better than its predecessor or had serious quality issues?

- A

Many might say the 24-70 f4 L is a disappointment, particularly for those that bought into it for the macro capabilities. The 50 f1.2 L also springs to mind  :)

Thanks, privatebydesign. Is that "11mm equivalent" two stitched frames from a TS-E 17?

Hi Nancy,

Yes it is from two shift stitched 17mm shots, they equate very well to an 11mm fov. But like I keep saying, I see the big issue is going to be projection distortion on the edges, when I do these shift stitches I almost always end up remapping them in PS by doing a 'spherical distortion' in the horizontal plane only, it brings the edges in progressively and actually works quite well.

If you are interested I'll post an example.

Maybe because Canon can't get around Nikon's patent to produce a competitive 14-24.  Nikon's 14-24 decreased the demand for its own 14 f/2.8. 

Very unlikely IMO.

Then why hasn't Canon done so, IYO?

takes years and years and more years to design and take a lens from concept to manufacturering.  comments from Nikon and I doubt canon is much different is around 7 or so years.

then you have this.. canon's optical R&D labs, lens manufacturing plants, and fluorite crystal plant were all hit by earthquake damage.

No it doesn't, not in the age of CAD, Sigma have said they can make a lens from concept meeting to production lens in between six months to a year. Canon have much more resources and probably tighter tolerances so maybe a bit longer, but certainly not years and years.

Photography Technique / Re: High shutter speed, low aperture but what ISO?
« on: November 12, 2014, 03:30:30 PM »
How much it matters really depends on your sensor. With the leverage like my 6d, you can get away with almost everything. With an older sensor like my 60d, it pays to have a little knowledge about iso settings because it can result in a big difference.

In my first year with my 60d, I was often using iso 1000 (sounded like a nice number) or iso 1250 (sounded like a nice step up). Looking at these shots, it was stupid - I should have gone to 1600 and higher shutter speed right away or stuck with 800 and ettr'ed.

If I was to add a caveat to my comment it would be to enable full stops only for iso, though I don't know which cameras allow that my old 1 series do. I only have full iso stops selectable and I only shoot stills and comparatively low iso so my experience might be very different from others.

As for your comment about people with less experience seeing things in another way, I agree, and it is one of the main reasons I hang out here, sure I get wrapped up in a dogfight sometimes, and I am often told off for it, but despite many peoples opinions of me I learn, and I learn a lot, maybe not about "lens compression" (good lord I just watched Franz Lanting say it!!!!) but I do learn and I appreciate everybody else's input, even if I don't agree with it sometimes.  :)

Well, I disagreed with pdb, so maybe you agreeing with me was to be expected :-p. But I still feel I might have finally got something right around here :-)

We didn't really disagree, you just added a caveat that I think Mt Spokane puts in even better perspective.

There will always be nuance that can be added to blanket statements, but we are all in agreement that lifting Canon files is one of their weak points, and for all but the most knowledgeable user that fully understands the tradeoffs inherent in particular exposure choices the broad advice to get a well exposed RAW image will be easier to work in post.

Of course we can start talking abut specific cameras and the point at which they have digital amplification, we can discuss the finer points of base stops and where they fall on the iso range, we can talk about the tradeoffs between loss of detail due to noise reduction and loss of tonality when underexposed files are lifted to any serious degree. But I think that misses the main point.

For the vast majority of people , most of the time, using the 'correct' iso will give them an easier file to work.

P.S. You often get stuff right Marsu, don't put yourself down! Your knowledge of ML is probably better than anybody else's here, certainly your enthusiasm and promotion of it is. Your talk of the dual iso capability almost makes me want to try a 5D MkIII!

Always choose higher iso and brighter exposed shot. Dealing with well exposed noise is much easier than dealing with underexposure and noise.

Lenses / Re: The next three new lenses? 50, 100 macro, 70-300
« on: November 12, 2014, 12:03:40 PM »
The 50/1.4 is old and tired.... a refresh with better build,optics and a ring USM motor has to come sooner or later. IS would be nice too.
The 100 macro? Still a great lens for the price, the only real improvement would be to add IS, but there's the L version, so that isn't going to happen.
I'm pretty sure the 50/1.4 has a ring usm already. The 1.8 doesn't. That thing is noisy as hell.
No, it has a micro USM motor, not as good.

I've looked and it only ever says USM. Nothing about micro USM.

It is correct, the 50 f1.4 has a micro USM motor. Many criticise it for the lack of durability, but I have had one in my bag for over ten years and it has never had an issue, in the same time I have broken my 16-35 f2.8 and 24-70 f2.8 five times between them.

With regards the 100 Macro. I don't see any chance of a MkII, I strongly suspect that Canon still has a container full of them and it is only in the lineup until they have gone, then that will be it just like they did with the 15mm fisheye when they brought out the 8-15 L fisheye zoom, they offered both for a while but then the prime, even though it is a great lens and an f2.8 against the L's f4, was dropped, and the price difference between those two is much greater than between the two 100 macro's.

If you want a cheap 100 macro and don't need the features of the L get it now.

EOS Bodies - For Stills / Re: 7D Mark II Reported Issues
« on: November 12, 2014, 09:30:32 AM »
anario,

My guess would be that it is a Yongnuo issue and a firmware update, for the third party flashes that have a USB port, will be along soon. Though that doesn't help you with the USB portless Yongnuo 568ex ii.

It is one reason I sold my YN-E3-RT, I wouldn't be surprised if Canon start playing hardball with these third party flash companies sooner or later by messing with new body protocols, just like they did with Sigma lenses a few years ago.

I tend to do this when I put my camera down. Bad habit?  Situational dependent? Or just muscle memory?

Do you do this? And why/ why not?

I do, and it grew from the fact that I have always disabled sleep mode, and in older cameras with poorer battery life it was a habit I got into to get more battery time.

Interestingly a lot of my work now is on a tripod and I had stopped switching it off between setups because I was using a Canon WFT and sometimes it wouldn't reconnect without hassle, but now I use a CamRanger that reconnects very well and I am switching the camera off again.

Looks like it works just like the Canon EOS-m to EF adapter, yes it is a screw and it you are so inclined you will want to Loctite it.

On the plus side, maybe RRS or Kirk will market a replacement Arca compatible foot. That would be a nice upgrade.

Never really bought into the replacement foot thing, I was always happy just sticking a plate on whatever Canon gave us, but I am sure RRS et al will be on the ball  :)

I expect Doug is using a 600 F4 Mark II with a 1.4x TC.

Brainfart, yes that makes sense  :)

How did you get an 840mm f5.6?

I'd be very curious to see what a rectilinear 11mm FOV looks like - that's wider than the rectilinear 8mm FOV of the Sigma 8-16 for APS-C.

This is what an 11mm rectilinear looks like, in truth it wouldn't be quite so wide but would be taller. The second image is a 17mm.

The real issue will be projection distortion on the edges, if Canon mitigate that (and I don't see how they can) then I will be first in line for one, I just sold my 16-35 f2.8.
