I've never had one lost, but I did have one B&H order go awry.  UPS ground from their NY warehouse to Boston is overnight, but I watched the tracking updates as the package went from New York to Deleware to Philadelphia.  Last I checked, Boston was in the opposite direction.

I called B&H, they sent another shipment that I received the next day.   :)

Software & Accessories / Re: What head with 055cxPro3?
« on: December 19, 2014, 08:04:44 PM »
(The Manfrotto MH055MO-Q6 is arca compatible)

Yes, it's fully compatible...with Manfrotto's own 'Arca-style' plates.  It's just not compatible with anyone else's Arca plates, L-brackets, macro rails, etc.  Manfrotto makes one excellent ballhead...the 468MG, worth getting as long as you get the clamp-less version and put a Wimberley C-12 or Kirk/RRS clamp on it.

EOS Bodies / Re: Ron Martinsen Blasts the 7DII in his review

Good point Neuro.  I didn't pick up on the subtlety of that.

I dunno.  Maybe he's quite reasonable.  After all, the 7D sucked – probably because it started getting noisy above ISO 800.  Many of his test shots are at ISO 6400.  Maybe expecting less noise at 3-stops more gain is perfectly reasonable.  Then again...maybe not.  ::)

As for the 'reach' argument, that's sort of a red herring IMO, the only thing a smaller sensor gets you is more MP, which isn't needed unless you're printing large.  Still, he probably has the answer for that as well – to go along with your more expensive body, replace your 300-400mm lenses with 500-600mm lenses.  But since ISO 6400 is so important, an f/6.3 lens won't work, you'd need f/4.  What's $10K between friends?   ::) ::)

Key statement from his review:

Quote from: Ron Martinsen
Now if you thought the 50D, 60D or 7D was a good camera then you’ll love the 7D Mark II. However, if you are like me and thought they weren’t worth owning if someone gave you one for free, then I have to advise that you stay away from the 7D Mark II – despite how fantastic the body features and technical specifications are.

Seems he's expecting FF high ISO performance from a sensor with <40% of the light gathering capability.  Maybe a tad unrealistic...just a tad.

That's an expensive habit you've got there.  Is there a twelve step plan available? :D

Yes.

Although...it's up to 14 steps, now.   ;)
Eek!  That's way too rich for my blood... think I'd better stick with my Samyang 14mm! :D

I have four MF lenses – three from Canon (17+24 TS-E and the MP-E 65), and the Samyang 14/2.8 (which I use for astro, and it's great).

So far, I've avoided being bitten by the Zeiss lens bug.  Well...for my personal photography, at any rate.  I've bought ~$2MM in Zeiss research equipment (not my money, of course), of which close to ~$200K was for 'lenses' (microscope objectives).

CCD will reappear very soon in top-level bodies and lens',

What will be the function of CCDs in lenses?  The mind boggles.....

UPS has missed 2/3 of their delivery dates in the past 3 weeks, I'd have thought they would have learned last year.  Most of my deliveries are routine, so its no problem.

This holiday season, 'Brown' is smelling like something else that's brown (or greenish-brown, says Mr. Hankey).  They've missed over half of my scheduled deliveries, including one that was a perishable birthday gift for a family member that was 1.5 days late.

Lenses / Re: 400mm DO II
« on: December 19, 2014, 04:53:33 PM »
I think the only way this lens is going to sell really well is if it proves to be essentially a 400mm version of the 300mm 2.8 II; that is, a lens with just legendary sharpness.   Otherwise, I don't know how you justify the almost $5000.00 difference between it and the new 100-400.   

How do you justify the 200/2L IS, when there's the excellent 70-200/2.8L IS II and the relatively inexpensive but still excellent 200/2.8L II?  Twice as much light.

Ah, but Neuro, doesn't having a super detail rig for studio (even if it's called 5D4 or 2D or whatever) and a 1DX Mark II beast for high fps outdoor work sort of split the goal of the unified 1DX anyway? 

Who's goal are you talking about?  If you mean the consumer goal of having 'one camera to rule them all' or something to that effect, then yes.  But Canon's goal is to make more profit...and the consumers' goals only matter insofar as they affect buying decisions.

Say they looked at their sales data and found few 1DIV owners with a second body also owned a 1DsIII, but many also owned a 5DII.  That would suggest a high MP non-1 body would be a more profitable path.

Lenses / Re: Introducing the Canon EF 100-400 f/4.5-5.6L IS II
« on: December 19, 2014, 01:13:30 PM »
I think apart from a rotating zoom (to which people seem to have mixed feelings) the usability with the TCs as confirmed by the MTFs, a reliable and more powerful IS, along with the much improved IQ is a sufficiently good reason for the widespread welcome this lens is getting.

Seems like the only thing missing is the much improved IQ.  Roger's initial, cursory tests over at the rental place indicate it's only around 4% sharper on average.  Of course there are other IQ considerations like flare, CA, distortion, contrast, color reproduction, etc., but 4% better sharpness isn't exactly a slam dunk.   ???

To be clear, I'm looking forward to getting this guy and I want to love the heck out of every aspect of it.  But 4% pales in comparison to the 40% improvement of the 400 DO II over its predecessor.

As I keep telling people, the old one was very good optically, but only under ideal conditions (IS off or stopped down a stop).  The new one seems to be massively better under regular high stress conditions (wide oopen with the IS in, and in resisting flare and CA.

My 100-400 was very sharp.  I think a key criterion for the MkII will be performance with the 1.4xIII, given the availability of f/8 AF on multiple bodies including the 7DII.  The MkI didn't take a TC well.  Given the 3rd party 150-600 options which are substantially larger and heavier, a lighter, more easily transportable 560mm f/8 would be a great option.  Looking at the TDP crops, the 100-400 II takes a 1.4x quite well, and the resulting combo delivers better IQ than the Tamron 150-600 @ 600mm.

But now, a new 50 MP FF rig cannot possibly push out anything near the 12-14 fps the 1DX can now (not at full res at least).  So Canon is stuck with a difficult choice here:

  • Split the 1DX back into its two camps and offer two new 1D bodies: one that is high res / low FPS for studio or landscape work and another with a different lower-res sensor that maintains a high burst for sports/wildlife
  • Only offer a studio/landscape high MP body and tell sports/wildlife guys to keep using their 1DX's (or possibly their 7D2's) until throughput improves down the road
  • Pull a 'sort-of-Nikon' and offer one body that is full res for studio/landscape but at the flick of a switch is a some-sort-of-crop high FPS beast.  APS-H fanboys can stop spooning with their 1D4's at night and move on with their lives.

All of those decisions have tradeoffs.  Not sure which is best.

You missed an option...don't release a high MP 1-series body.  The rumor here (CR3, so CRguy believes it's pretty accurate) indicates a non-1-series body for this release.  It seems likely to me that Canon will give a slight resolution bump to the 1D X successor (24 MP, perhaps) and keep the 12 fps. 

They unified the 1D and 1Ds lines for a reason.  While no doubt there are some who bought both, having a 1-series speed demon and a 5Ds/4D/whatever high MP body for studio/landscape may be a more viable option from a sales/marketing perspective.  It's one I'd personally consider (but then, I'd also consider a 1D X + 1D Xs combo  :) ).

The switch from CCD to CMOS, which need(ed) to be read out in the dark, necessitated a mechanical shutter.  dSLRs use a focal plane shutter, I don't know that Canon has ever used leaf shutters.

We don't read out CMOS sensors in the dark when using them for video, so obviously that's not essential.  I'm pretty sure the real answer is that it's cheaper to toss a leaf shutter in than to do it right....  :)

As Lawliet correctly points out, there's a good reason why the sensor is read out after the mechanical shutter closes.  Maybe you wouldn't mind being limited to slow shutter speeds, but for those of us who need to stop action, eliminating the mechanical shutter is not a tenable solution.  As readout electronics and speed improve we will eventually get to a global electronic shutter for dSLRs, but we're not there yet.

Also, as I stated previously, Canon dSLRs do not use leaf shutters.

It almost needs to be both semi-high fps (at the very least in cropped modes (sRAW or mRAW speed won't do it since those kill all the reach for sports and wildlife)) and high DR otherwise if it is very slow then it's not longer quite as great for sports and wildlife too...

Although I'm sure many of us consumers would want that, I doubt Canon will see it as a need.  I say 4 fps max, no crop mode.

No the point isn't to thread a screw in there.  Hell that would really muck it up..  The idea is to use it as a set screw so it won't twist.  You set the screw in place and just tighten the main screw that has the threaded insert.  That's how I've used other large lenses in the past.

The big Canon lenses have two threaded holes on the tripod foot (one is 1/4", the other is 3/8").  The long RRS and Wimberley plates for them come with two screws.  I don't know of any other Canon tripod foot, except the EF-M adapter and now the 100-400 II, that has the camcorder-style anti-twist pin hole.
