Lenses / Re: 6d/100L macro/Kenko 2X TC lockup
« on: December 26, 2013, 11:21:03 AM »
Nope, it's a bug with Kenko.  Complain to Kenko.  properly.

Complaints have been made, and they already deprecate the tc with 5d3/6d because of this bug... no way to "fix" it than to replace the whole thing since 3rd party manufacturers (Sigma, Yongnuo) only recently got smart enough to put usb interfaces into their products.

Clearly did not reverse-engineer Canon's software properly.

I doubt that, they re'ed what was the lens-body protocol at the time - but Canon changed or extended it, at least to enable dual afma for zooms. No one knows the change necessarily meant breaking the competition's products, but personally I don't think Canon minds a lot as they sell their own tcs.

I don't think so.  The version II TCs were out before the 6D/5DIII and did not need to be revised when the 6D/5DIII came out.  Canon extended the protocol, but what was existing worked as before.  That Kenko did not get reverse-engineer the software correctly is not Canon's fault.  That is the risk of buying third party parts.  My original post is that it is not Canon's fault that Kenko does not work with new cameras.  Kenko could have updated the software/firmware for a nominal fee, but chose not to.  Not Canon's fault.  Dgatwood's point is that it's Canon's responsibility to have their equipment work with third party parts.  I'm saying it's the other way.  What Sigma is doing is a step in the correct direction.

Thanks for your replies. Shutting off AFMA solved the problem, but as my 100L needed a +9 AFMA, not sure the overall solution will be satisfactory...

Complain to Canon.  A camera body locking up (freezing) is an unacceptable firmware bug, regardless of whether it occurs with Canon's lenses or someone else's.  It's a bug, and Canon needs to fix it.

Lenses / Re: Change Canon 17-40mm f4 L for Sigma 35mm f1.4??

You'll probably end up with the S35 in addition to the 17-40, but not as a replacement.  If anything the S35 would slot where your EF 40 is, but if you intend to use the 40 for street, then you'll end up with both.

I've got UPS "MyChoice" and can direct any delivery to my local UPS store.  It is afe there until I can pick it up.  This eliminates the box outside the front door when nobody is home.......especially boxes with words like B&H or Adorama on them!

I almost always have deliveries go to work – indoor loading dock, always someone to sign for them, and they get brought to my office. But I'm off for 3 weeks over the holidays, so they're coming here.

Apple products or consumer stuff delivered to work magically "disappear."  iPads someone ordered for a project were "lost" that way. 

Lenses / Re: Samyang 14mm f2.8 - focusing

I have heard that at f8 the DOF is massive - it's mainly for focusing on foreground objects I am struggling.

I am hoping the AF chip I have ordered helps, I dont want to have to spend five minutes setting up each shot and checking focus.

DOF increases quite a bit but the depth of critical sharpness is still thin, so it ultimately depends on how large the final image will be.  I find that I often prefer having the subject critically sharp and letting the DOF fall where it may rather than burying the subject in the zone of acceptable sharpness.

I love UPS because they are consistently awful. I know if I get the alert my package has been delivered and I haven't had a knock at my door I know to check the house at the end of my road that is #520 since my house is #620. It blows me away how often this happens. Even with stuff that says "Signature Required." Amazing!

Reroute it and pick it up at the depot instead.

Lenses / Re: Two New 24-70's Coming in 2014? [CR1]
« on: December 22, 2013, 09:59:53 PM »

$2499 for 24-70II to well under $2000 in just over a year.
$1699 for 24-70 f/4 to under a $1000 street price (as cheap as $899) in less than a year.
$849 for 35mm f/2 IS to $549 in about a year.
Etc... (and don't even get started on the EOS M)

It shows their overpriced policy backfired and supply was over demand making the lens drop in value

Probably not.  More like a variation of first degree price discrimination.  Canon has a price that it willing to sell at for a profit.  Anything they get above that is gravy.  Early adopters are willing to pay more, and Canon is turning that willingness into additional profit.

It isn't the amount of boke I was referring to. I hope you don't mind me using your photo, but here is a 100% crop that demonstrates the strange concentric rings inside of each boke blur circle (are you saying that funky effect is because the light sources are christmas lights?):

Are the concentric rings a function of the grinding process of the aspheric elements?  I noticed it in the 24-70 II, and the rings go away when the blur circle is a lot brighter.  It might be that the candles flames also have the same "feature" if the exposure is reduced by a few stops.

Try these guidelines from a previous thread:

Some people have added a focus confirmation chip to it or they use a different focusing screen.  Others learn to set it to max DOF.  But if the FG subject is close and you want critically sharp focus (rather than trying to hide it in the DOF), then live view is the way to go.

Canon EF Prime Lenses / Re: Canon EF 28mm f/2.8 IS USM
« on: December 21, 2013, 01:05:04 AM »
Intrigued because it has IS for such a relatively wide focal length, and I picked up a new copy when it was on sale for $350.  The IS can be useful, but I find it more useful at longer focal lengths.  About twice the size as the shorty forty

Handheld at 1/5s.

Normal.  The 24-70 II is a great lens and its color and sharpness are comparable/better the primes in the range, but bokeh is not its strong suit.

4mm of zoom? Why bother? I guess there is quite a difference between 16mm and 20mm on FF but why not just pick one focal length and make it awesome. Like 16mm or 17mm f/2.8 would be perfect.

Would this lens be the worlds shortest zoom if it was made??

Yeah, it might be even less, depending on how marketing "rounds" the numbers.  For all we know, it could be a 17-19, lol.

Interesting, but with such a narrow zoom range, why not just make it a 16 f/2?
