EOS Bodies - For Video / Re: The First Canon EOS 6D Video Footage

What surprises me is Canon has again released a brand new XD series without a headphone jack.
The 1D X does not have one and now this latest model from Canon does not have one.

But the 1D C does, as does the 5DIII.  Seems like Canon is differentiating between bodies that can shoot video (which is all of the current ones, obviously), and bodies that are intended to be used for video.

Lenses / Re: What UV filter for new 70-200mm (77mm filter size)?

How about this B&W?

Nope, this one.  The one you linked is the F-Pro mount, and you want the XS-Pro mount.  The F-Pro causes a slight increase in optical vignetting on the 70-200/2.8L IS II (unusual for a standard filter to vignette on a telephoto lens, but it does on this one - I've checked it myself). 

I agree with Neuro...go with the clear, MRC, brass ring...they are the best...You do not need the UV protection on a digital camera ...that is a factor with film...took me a while to break that habit.


You don't need UV for digital, true.  But it doesn't hurt, either.  Depending on filter diameter, vendor, and geography, sometimes the UV version (010) is cheaper, sometimes the Clear (007) is cheaper.  On amazon.com, the 77mm XS-Pro UV is $80, and the 77mm XS-Pro Clear is $115.  Since there's no optical difference for a dSLR, I recommend getting whichever one is cheaper.

I'd get a B+W XS-Pro (MRC or Nano, UV or clear, whichever is cheapest).  In the Hoya line, I'd pick S-HMC at a minimum, or the Pro1 or HD filters, but not regular HMC.

The HD line is reportedly easier to clean (like the B+W MRC and Nano coats), whereas the other Hoya filters can be more problematic for cleaning.

Ultimately, if I can't tell the difference in real world shooting...

That's true, today.  But in a few years, the entire world will be composed of QR Codes, and then FoCal results will be universally applicable to all pictures.

EOS Bodies / Re: First Round of EOS 7D Mark II Specs [CR1]

I wish they would build it with the battery grip, however I know that would be very inconvenient for many folks that don't like it or it's too large for.

I don't see why anyone would want the grip to be built in and not removable.


Granted, it's a limited and self-selecting population, but in the recent Custom Brackets poll, more people have gripped bodies than not, and the majority of people who have a grip on their body use it frequently.

It has a great matte finish that matches the lens body, and unlike the lens hood of so many of my "L" lens that I have owned, seems highly resistant to marking. 

That's Canon's new hood finish - the 70-200 II has it, etc.  The 70-200 II also added the locking hood design that the 24-70 II uses, too.  Both are great features, IMO.

i fully understand what you say... but then... this is a new product.
when a new product is not better then a older one there is no sense in wasting money on it.

that´s why i critizise the 6D video.

Define 'better'.  For some people, the lower cost of the 6D makes it significantly better, especially if the IQ is no worse...

Both are excellent.  The 24 II is a little sharper.  But really, it comes down to focal length - is 24mm wide enough to frame what you need?  Architecture sometimes needs a wider AoV.  Personally, I'm very pleased with my 24mm...

I just picked up an Induro 414 so that might help with the stability issues...

Have you tried running tests at higher ISO or should we stick with using 100 for all tests?  I can see with the 2XIII the tests will require a couple of suns worth of light.

I've got a rock-solid tripod and gimbal head.

I've shot some at ISO 200, it works fine.  But I did my outdoor testing in direct sunlight and added 450 W-equivalent of halogen lighting, so even at f/5.6 my EVs were in the ~15 range.  That was giving me a shutter speed of 1/1250 s at 840mm with the 1.4xIII.  I haven't done the 2xIII yet, but assuming I have 15 EV of light for that, I'd probably use ISO 200 to keep the shutter above 1/1000 s.

I still desperately need to get some sort of bracket to put my flash in a useful position for macro work,

Great shots!

A reasonable budget option is one I have, a Manfrotto 233B with a Giottos MH1004 mini ballhead on the end (and you may want an OC-E3 or 3rd party equivalent, although you could trigger with the onboard flash).

I also have an RRS flash bracket (B91-QR with FAQREX-2 extender), and a couple of Wimberley F-2 brackets - those are, respectively, expensive and moderately expensive options, but very good quality.

The t4i shoots up to 6400 iso. It appears with a side job I just landed this morning, the 70-200 2.8 non IS will be in reach.

Actually, it goes up to ISO 12800, with ISO 25600 available as an expanded setting (H).  But whether ISO 6400 is actually usable, much less ISO 12800 or higher, is another matter.  Just because the setting is available, doesn't mean you should use it - the 1D X has ISO 204800 available, but it's not even remotely usable. 

Reportedly, the T4i actually a little noisier than the predecessor sensor (the one in the 7D, 60D, T2i, T3i).  That's probably artificial due to some tuning by Canon, since it's sharper than the predecessor sensor, too (noise can be traded for sharpness, and vice versa).  Personally, I find ISO 3200 on the 7D to be usable, but only just, and I really prefer to keep the ISO around 800.  But, noise tolerance is subjective, so if you're happy with ISO 6400 on the T4i, great!

Furthermore, Canon is including a lens hood and bag with this new lens (35 f/2), which indicates to me that this lens is a cut above the typical non L prime.


It's now been pretty much confirmed (by two separate sources from Canon USA) that this is NOT true - the 35mm f/2 IS will ship without hood and pouch, just like nearly every other non-L lens. 

Note that in other geographies (some Asian countries), all lenses ship with a hood, even lenses like the EF-S 55-250mm and the 40mm pancake.  But not here in the USA.

+1 - it's wickedly sharp.

How did you do this one? Macro tubes? Could you describe it?


That was a 100% crop of this image:


EOS 7D, EF 100mm f/2.8L Macro IS USM, 1/60 s, f/8, ISO 400, 430EX II on Manfrotto 233B flash bracket via OC-E3

No tubes, just the bare lens on a 7D.  With the flash bracket, the flash head was right at the end of the lens hood (with a StoFen on the flash).  I was just walking along a trail, and the fly was sitting there on a bush.  I pointed, I clicked...   ;)
