Software & Accessories / Re: Canadian source for SD cards in bulk?
« on: September 20, 2014, 10:17:01 PM »
Anyone?  I'm after the 400x 16GB pro SD cards particularly, fifty or so of them.

Jim

I would suggest you call up your local computer store.... not one of the big chains, but a smaller operation....

BTW... near me...for the Sandisk 16G extreme
Henrys Camera - $24.99 on sale, regularly $32.99
RBC computing - $19.10 on sale, regularly $20.00
Best Buy          - $27.99

Guess which one will bive you deals on bulk orders....

Zero lag.
Zero power usage.
Infinite dynamic range.
Infinite color gamut.
Automatic match between viewfinder illumination and scene illumination.
A total dynamic range (bright sun to night scenes) equal to the scene, which can be about 10-12 stops more than an EVF can manage.

Not to be picky.... but.....

Zero Lag.... not quite... it's about .5 microseconds for the light to travel through the prism.... but that's about a 30 thousandth the time of the best EVF's... for the stuff I deal with at work, .5 microseconds is freakin' slow! :)

Infinite dynamic range and color gamut? That would require travelling through a vacuum... you loose some of each passing through glass and through atmosphere.. It is certainly far superior, but it is not infinite....

Light can go 500 feet in .5 microseconds.  Did you mean .5 nanoseconds?
repeat after me....

I love autocorrect.... I love autocorrect..... I love autocorrect......

autocorrect changed it on me! .5 nanoseconds is the correct answer....

By the way.... the local coffee shop chain around here is called "Tim Hortens". Autocorrect changes it to "Tim Horrendous"...

EOS Bodies / Re: Just for Jrista: 2014 Market Data
« on: September 20, 2014, 04:45:55 PM »
These threads pop up occasionally and often sales volume, market share and profits are quoted to try and prove one sensor or camera company is better than the other.

This information is good if you are considering buying Canon stock CAJ but absolutely worthless in determining who has the best camera or sensor.

Of course, proving which camera or sensor is the best isn't the point of bringing up sales data and market share.  But if you want to deliberately misconstrue the reason in order to dismiss the information, that's your choice.

What I find funny is how people try to use these statistics to show how the 1DX is better than the D810 (and vici versa) and fixate on high end camera comparisons..... Yet the vast bulk of sales for both Canon and Nikon are the introductory crop cameras and the two biggest factors used by the average consumer are price and megapixels... Image quality, autofocus, DR, expensive lenses, and all the other goodies do not factor into the decision, and most of these cameras will live their lives in "green box" mode.....

Lenses / Re: What do you use your wide angle lens for?
« on: September 19, 2014, 05:24:30 PM »
and a bit more seriously.... I use it for panoramas too. Put the camera in portrait mode and snap off a dozen shots and stitch them together for a really wide view without horrendous distortion....

I use mine for bird photography....

The red arrows point to Great Egrets, the blue arrow points to a Great Blue Heron, the green arrow points to a cormorant, and the purple arrows point to some mallard ducks. :)

Oh Lord, once again we rave about jpeg noise reduction algorithms...
and none of the sample pictures have squirrels :) You can't go nuts without the squirrels coming out......

EOS Bodies - For Stills / Re: Do you need a really high ISO?
« on: September 19, 2014, 09:18:42 AM »

Would it make sense to ask what the approximate ISO of the human eye is? In other words, how much higher does the "usable" (admittedly not well defined) ISO need to get for the camera to perform as well as the human eye, with comparable detail, noise, etc.?

In the early days of digital, there was constant discussion about how many MP were needed for digital to be comparable to film, even though the image characteristics are somewhat different (14 MP was the generally agreed upon answer, as I recall). My question is sort of in the same spirit.
One of the problems with that is that in the daylight we have high res colour vision and at night we have low res b/w vision.... Also, note how long it takes for the eye to adjust to darkness..... about 5 minutes for full sensitivity... we can't just rotate a knob like on a camera :)

Speedlites, Printers, Accessories / Re: CF Cards Vs SD Cards
« on: September 17, 2014, 09:42:24 AM »
Yup...enough with the fear mongering. 

I've been shooting CF cards for 15 years and not once have I bent pins or messed up the mechanical interface in any way.  I've had exactly one card go bad in all that time (of hundreds I've owned), and that was when one fell out of my card wallet and got run over by a fire truck.
CF cards in cameras.... in routers... in laptops... in spectrum analyzers.... in satcom modems.... for many many years and no bent pins yet either....

(I have a bunch of 16Mbyte ones in a drawer at work..... they have been around for a LONG time......)

SD cards are cheaper per GB, more devices can read them, and unless you are running your camera in burst mode, you should have no problem keeping up. If you are firing off more than a picture per second and keep it up for a while, you will fill the camera buffer and a fast compact flash card is faster than a fast SD card and will clear the buffer sooner.... but the difference is not noticeable until you get to the very fastest compact flash cards.... or so conventional wisdom says.....

but if you look at Sandisk and the fastest cards that they sell:
Sandisk extreme pro  HSII 64G SD card - 250MB/s write speed, $230
Sandisk extreme pro UDMA7 64G CF card - 150 MB/s, $200

You end up with an SD card that is both faster and more expensive.... the exact opposite of what people believe to be the truth.

This is very interesting! So perhaps I should shoot with an SD card and if I hit limits with it, try CF.

Don & pleasehelp, much appreciated :)

I tend to shoot with jpg's and RAW.... For me, the best way to go for speed is one of those 90MB/s SD cards for the jpgs and a 150MB/s compact flash card for the RAW files.... that gives you the fastest speeds and an image backup....

It does not say in the specs if it accepts UDMA 6 or 7 ( I would assume 7) compact flash cards or if it takes UHS 1 or 3 SD cards (I would assume UHS 1). Hopefully we will know as the release date gets closer...

Software & Accessories / Re: How do you carry your tripod around?
« on: September 16, 2014, 07:22:29 PM »

3. overnight hike: I had been using the f/stop gear Satori, really a great pack, plenty of space for camping stuff if you use one of the smaller inserts. I made straps to attach a large tripod to the center front of the pack. However, I found the pack fit not right for me for half-day or longer hikes with 30+ pounds (15+ kg). As it turns out, the effective torso length is 18", about average for a man, slightly larger than average for a woman. I, however, have a torso length of 14", and that is enough difference that no amount of strap adjustment and load adjustment will make the pack ride right. So, this year I will be trying an ordinary backpacking pack in women's extra-small (Osprey Ariel 65), and again fiddle with home-made rig to hold tripod to pack. The Osprey pack has a J-shaped front-panel access, so I will probably try to sling the tripod diagonally to preserve access.

A lot of ladies sing the praises of Osprey packs....
