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 :)

Hi
I'm now using 5DIII and a 300/2.8L IS +1.4xIII mostly for birds

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....

EOS Bodies / Re: How excited are you about the new 7D II?
« on: September 16, 2014, 06:55:31 PM »
I am very excited. I want a camera for action, birds, and backcountry camping trips. This camera seems to be designed for that....

As said repeatedly in the past, who cares what the DR or pixel count is of an out of focus picture. This new AF system appears to rock!

All great and interesting points.

To me, it is most telling when "pundits" bash the cameras without actually and objectively seeing what they can do.  Instant loss of credibility.

I find it interesting that the people whining about "I don't want video functionality on my stills camera" are being drowned out by the "the camera is crap if it does not have 4K video" people....

The we have the "I want more pixels" people and the "I want less pixels" people...

talk about conflicting demands!

In the good old days of film, I shot a lot of Kodachrome64... When lighting was not good your options were to use artificial lights or stop taking pictures. My second body usually had a roll of "high speed" film in it... ISO400 or ISO800..... same problem.... loose the light and you go home.

My first digital DSLR was unusable at ISO800 and topped out at a very noisy ISO1600. Now there isn't a DSLR (or mirrorless) on the market that does not produce better results at ISO12,800 than film did at ISO800.... and the numbers are slowly creeping upward.

Last night I mounted a laser pointer on the top of my camera and tried taking pictures of the cats chasing the red dot. You could not see the red dot. I turned the lights down low and cranked up the ISO to 12800 and it worked very well. These are shots that were impossible before and I have come to accept this as normal.... so yes, I need high ISO....

« on: September 15, 2014, 10:49:09 PM »
I want to know why the 7D2 does not have a little laser light that shines where the camera is aimed? Everyone knows that the only use of APS-C cameras is to take pictures and videos of cats to put on the internet.... and the videos would be so much better if the cats were chasing that little red dot....

Come on Canon! This is a make or break feature! Why don't you have it!

It might sound funny but I actually wished for a feature like this, not for cat shots but for shots I take from my hip when doing street photography. Then it would be nice to know at which spot the AF is currently aiming. Of course the laser should be off during the shot itself.
and what's really sad is that I had to try this out.....

BTW, the 60D does not have adequate high ISO performance to take good "laser pictures".... I KNEW there was a good reason why I need to upgrade to a 7D2 :)
