EOS Bodies / Re: DSLR ? - thinking out loud ....
« on: July 19, 2014, 05:04:33 PM »

And you have hit the big problem with mirrorless.... battery life. They increase the power consumption and make the battery smaller.... and for some inexplicable :) reason, battery life sucks! If they kept to LP-E6 they would last longer... or with a mirrorless in a "normal" sized camera there would be room for a larger battery.

For comparison,
70D, LP-E6 battery, 1000 pictures per charge
EOS-M, LP-12 battery, 230 pictures per charge

LP-E6 is 7.2V and 1800mAh
LP-E12 is 7.2V and 875mAh

If you look at in term of pictures per Ah, the 70D is 555 per Ah and the EOS-M is 265 per Ah.... so assuming the same battery capacity you are still at only half the life on the EOS-M as the 70D

Of course, according to the official Canon numbers, the 70D only gets about 230 shots in live view, or 152 shots per Ah.  I can't imagine why its battery life in live view mode is only half that of the EOS-M, rather than being about the same, but there you go.  Either way, the point remains that active displays draw a lot of power.  :)

FWIW, this past week I shot over 500 frames (and a 90 s movie) on a single fully-charged LP-E12 in my EOS M (and I could have shot more, but I swapped in a fresh battery as soon as the red-flashing indicator came on).  I shot about the same number of images on my 1D X, and used less than 35% of the LP-E4N's capacity (no need for the spare battery this trip).


The more useful statistic would be minutes with the screen lit.  Taking the photo is lost in the noise by comparison.  If you shoot photos relatively quickly, you'll get a lot of shots.  If you take five minutes between shots, you won't get very many at all.

That's rather the point, isn't it?  Previsualize the shot, turn on the camera, compose, focus and shoot.  If there are people in the shot, fire off a ~3 frame burst.  Don't spend a lot of time chimping.  Good technique can make more effective use of battery life.  The >500 shots on one battery were spread over three days of use.

Photography Technique / Re: Importing Images
« on: July 19, 2014, 01:30:39 PM »
Thought one: use a card reader.

Thought two: first copy to desktop (HDD/SSD) using Finder, then Import (then erase the copy on desktop).

Not AFAIK.  DxO or LR might support it, though.

Yes.  Make your edits, export the sidecar file.  Transfer image and sidecar to other computer, import sidecar, then export image.

If interested here is a quick informal test I did yesterday. Crop cameras are the best birding cameras IMO beating a FF pretty handily. Especially with the new crop sensors from sony.

Interesting that Art Morris (of who's website your URL is seemingly a parody, and who actually shoots birds instead of posed pooches) uses the 1D X and 5DIII with Canon 500/600 II lenses and delivers impressive images. 

I must say, your opinion smells like birds that fart.  :-X

  Non sense.  I personally do not like his pics that much, but many do.  Many others that use Canon equipment I like much better.
Just went to your site. Looks like you use the 1dx and 5D III & 600 II.  Birding photography, you are not very good IMO. Very poor.  Jrista, on the other hand is very talented IMO. But, I don't have to agree with him for sure.

  Great hobby though.... all the best.

Thanks again for sharing your opinion.  You already know what I think of it...

Enjoy your hobby!

The point being, don't fixate on gear. Technique beats gear every time. One of the best techniques to learn in bird photography is to be slow and quiet..... although that said, I would not refuse a 1DX and a 600II if it were offered :)

My point is that good technique plus excellent gear beats good technique plus decent gear.

Here is a very good and well respected pro bird photographer who uses a 7D:
http://www.glennbartley.com/


Indeed.  However, he states:

Canon 1DX
If money was no object for me I would definitely own this camera. The file quality is amazing and the autofocus superb.   At this point for me though the price is not justified. Furthermore I like to use crop bodies.


I think many people say they prefer crop bodies because money IS an object.

He also goes on to say:

The result of these smaller sensors is increased focal magnification. For example, if a camera has a 1.6x crop factor a 100mm lens will become a 160mm lens or a 300mm lens will become a 480mm lens.

The crop factor is just that - cropping.  The fact that he seems to think it's a 'magical physics-defying focal length increasing factor' indicates he doesn't have a very good grasp of the relevant technical details.

When I got my Tamron 150-600 I rushed outside to take some bird pictures.. I finally had a long enough lens that I could shoot tiny birds, and using it on a crop camera increased the equivalent focal length to 960mm.

I put a 2x TC behind my 600 II on my 1D X, then I cropped the image to 25% which increased the equivalent focal length to 2400mm.  If I mounted an iPhone behind the 600 II + 2x, that would increase the equivalent focal length to 9600mm.  Where does it stop?

The crop factor ("equivalent focal length" is just cropping) is only an advantage IF you're shooting at low ISO and IF printing larger than 16x24"/A2.

There is no crop factor advantage if taking pictures of chickadees eating from your hand...   ;)

EOS Bodies - For Stills / Re: HUMIDITY ALERT!
« on: July 18, 2014, 09:32:56 AM »
I store my gear in Storm hard cases with desiccant cartridges inside the case.  The desiccant has an indicator dye that turns from blue to pink when it needs to be replaced.  There are also humidity controlled 'dry boxes' to store gear.


Neuro, can you please elaborate on the "desiccant cartridges"? Is it part of the case or stand-alone product? if such, can you post a link to the product?
Thanks
Eli


I use these:

http://www.amazon.com/Bel-Art-Scienceware-420480100-Disposable-Desiccant/dp/B002VBW9XC/

I get them from a scientific supplier for much cheaper.  Search B&H for "desiccant" for a reasonable metal canister option that you can regenerate in your oven.

Canon General / Re: New Speedlite Coming? [CR2]
« on: July 18, 2014, 08:38:52 AM »
lets not forget that if you have a grip, it comes with the AA adaptor so you can run your camera on that...ya gotta figure if one 5d3 battery can power the body for a few thousand shots, one of those in a speedlight could go for a week!

A week of very long recycle times. You can forget an LP-E6 battery pack that works optimally in a bunch of cameras and flashes.  Li-ion isn't optimal for fast-draw applications like refilling a capicitor.  Canon would ideally make an NiMH battery for that, and the form factor would need to be different to avoid confusion.

EOS-M / Re: The promised pics of the 18-200 Tammy
« on: July 17, 2014, 07:52:55 PM »
The 10-18 seems like it might be a good match (if you already have an EF/EF-S ->M adapter).  Getting good reviews and pretty small. Any reason not to go this route?

I just got a 6D, kept my 60D as a backup/beater camera, so the M is relegated to times I'm bringing some sort of backpack or shoulder bag while playing tourist but not so much that I'm bringing one of the bigger cameras. Debating whether to invest in a wide-angle (trip to Italy coming up), or pare back even more and spend the money on something like an RX100iii that takes great photos but is more limited in focal length.

The 11-22 is significantly smaller than the 10-18 + adapter. 

I had been considering the RX100 III, since I used to bring along a PowerShot S95/100.  However...in bright light, small sensors do fine (nearly as good as larger sensors if you don't need shallow DoF), but in dim light you want the biggest sensor you can carry.  That's what I like about the M – relatively larger sensor in a small package with lens flexibility.  The 11-22 and 55-200 together aren't much more outlay than the RX100 III.  The M + 22/2 does decently in low light (not nearly as good as my 1D X + 35/1.4L, though).

I find the M + 18-55 carries nicely in a Lowepro Dashpoint 30 on my belt.  I have the 22/2 pancake in a Lowepro Lens Case 8x6 in the backpack that I bring (I have 3 kids, one 15-months, so I need snacks, diapers, water, raincoat/sweater or towel, etc., on pretty much every outing).  The 8x6 case holds the 18-55 when I swap.  The other two M lenses would be easy enough to carry in separate lens cases, and the whole kit would take less room than the 1D X + 24-70/2.8 II even in a neoprene cover in the backpack.
