Lenses / Re: Canon EF 100-400 f/4.5-5.6L IS II [CR1]
« on: July 14, 2014, 11:47:18 AM »
I am sticking with my non-stabilized 400mm f/5.6L until I can afford an f/4 supertelephoto.. I would not advise beginning birders to start with a non-stablized lens. unless they have lots of patience.
I keep hoping to see an updated version of that lens..

Technical Support / Re: Landscare photography and bicycling
« on: July 13, 2014, 10:40:21 PM »
I will be going to Colorado for vacation (Grand Mesa) and will be doing lots of bicycling during the week that I am there.

Purchased the new 16-35L specifically for the purpose of taking some great (I hope) landscape photographs.

But wondered if others have experience about the best method for holstering my DSLR/lens.

My plan is to bicycle, stop when something catches my eye to take photo, continue.

Does anyone else have any experience with this ?

I have used a handlebar bag filled with soft foam to carry my DSLR.... and so far it has survived :) but something mounted to your back, like a hydration pack, would subject it to a lot less vibration.

Since we're speculating...

7 years down the road your pro/semi-pro camera will not only be mirrorless, but will have no built-in display and limited controls.  Instead, it will have a dock for your smartphone, which will serve as the control panel and view screen.(*)

(*) Not an actual prediction, for entertainment purposes only.
actually..... I would love it if I could use the Wi-Fi on the camera to connect to a smartphone or tablet and have the device act identically to the screen on the camera, or in the case of a tablet, have all the controls at your fingertips...

I think a few years down the road, that there will be no discussion or competition between mirrorless and DSLRs.  They are so close already in ability to take professional photos that I think people will barely differentiate between them.  I own both a Canon 6D and an Olympus EM-1 and they both do an excellent job.  I never refer or think about them as one DSLR and one mirrorless camera.  They are cameras, that's all!   

The competition will be between cameras and cell/smart phones.  For the average person, their smartphone will do everything they need in terms of taking pictures.  So camera sales will continue to decline and eventually plummet.  When the current generation of kids reaches adulthood, smartphones will be so far advanced from where they are now, the vast majority will feel no need to use anything else.  Older folks may continue to buy cameras - and, of course, professionals and serious amateurs, but the only arguments will be smartphone or camera? - not mirrorless or DSLR.  That's what my crystal ball says!

This was just between sunset and sunrise.

Noon?!?   :P

Sunset at 0:05 and rises 2:40, so it actually doesn't get dark in the summer.  ;D

I like the picture....

I figured it was somewhere north like Norway or Finland from the times given... So where was the shot taken?

As for the DR and color, that's precisely why I want an EVF: I want to compose using what the sensor can see, so I have a better idea of the final image.  This is another plus for EVF.

So you want a better idea of what the in-camera JPG conversion will look like, if displayed on an uncalibrated monitor with low resolution and a poor color gamut?  Sounds like a big minus for EVF to me, particularly for anyone who shoots RAW...

I'm surprised, you don't usually make bad arguments.  You have invoked the "it is thus and ever shall be" argument.  I'm saying I want an improved Live View through the viewfinder, and I believe it's achievable in the next few years.  I'm not saying current EVF is adequate.

You said more than merely 'improved live view', you said you want the EVF to allow you to, "...compose using what the sensor can see," in terms of color and DR.

RAW data is 14-bit, displays and EVFs are generally 8-bit - that's a significant gap in color and DR.  The highest-end professional video editing displays and EVFs support 10-bit color, and I suppose you are suggesting that displays will catch up...but high-end cameras (I have some in the lab) use 16-bit ADCs, and those will also show up in mainstream consumer imaging down the line. 

You are apparently assuming display technology will improve while image capture technology remains stagnant...sorry, but that's the bad argument here.  Both are improving (and will likely continue to) in parallel, and given the already large lead that image capture has in terms of bit depth, it's highly unlikely that you'll ever be able to look through an EVF and 'see what the sensor sees'.
I thought it was obvious what Orangutan meant.... guess I was wrong....

Sorry, EVFs don't show that, they show the in-camera JPEG conversion, which is way, way smaller than what the sensor can see.  I post this example often:
The fact that they don't currently doesn't mean they can't very soon.  Do you ever use Live View?  I'm still unpersuaded that, aside from battery life, there are any serious problems with EVF that can't be overcome in a very few years.  And, when that happens, EVF will be indisputably superior to OVF.
I have a pair of the Olympus "tough" waterproof cameras... One is about 4 years old and the other is last years model. A friend just bought the latest version. On the 4 year old one, lag is very noticeable and the viewfinder sucks in poor light. On the one year old one, lag is not noticeable and the viewfinder is noisy in poor light. On the new one, there is no noticeable lag and the viewfinder is close to what the eye sees in poor light.

This is the march of progress. Just using this as an example, four years ago I would have said that EVFs are a long way off, but today I would say that they are close..... and this is with a cheap P/S camera. The viewfinder in the OMD EM-1 is superior to this EVF... and what is coming down the pipes? What do Canon/Nikon/Sony have planned for the future?

Ever use liveview on your DSLR? Ever zoom in 10X to check the focus? This is a trivial problem for an EVF, yet impossible for an OVF.... you have the option to switch between what the sensor sees and processed views....

And now lets travel back in time to the origins of the SLR camera... it was an ingenious design that allowed the eye to see the light that would be presented to the film. A DSLR with an OVF is the same, it allows your eye to see the light that is presented to the sensor. An EVF goes one step further and allows you to see the light as viewed by the sensor.

New cameras have ten times or more computing power than those of just a couple years ago... they can do complex noise correction on the fly.... the on-the-screen jpg of four years ago is not the same as it is today. You can not use the inadequacies of the past to justify the future.

When we will know the final specification for Canon 7D Mark II


When Canon makes an official announcement. Until then it is rumours and speculation.
19Mpixels, 8.5 fps,  23 AF points, 0.5 stop improvement   ;D   ;D   ;D
I prefer my speculation on the wild side.... I predict that the 7D2 will be mirrorless. I have a perfect prediction record..... wrong every time :)

The thing about Canon (and many consumers) is that they are conservative. When the day comes that mirrorless cameras offer better performance than DSLRs, and right now it is the AF and EVF that are lacking, the day of the DSLR will end. When they can make a better camera and sell it for less, where do you think the consumer will go?

I am particularly interested in what happens with the 7D2.... DPAF has the potential for superior autofocus to existing DSLRs.... and EVFs are getting close. There is a real possibility that this camera will be the tipping point.

I could imagine that eventually dSLRs will fade out, in the sense that dSLR style bodies would no longer be equipped with a mirror. With technologies improving, I think that eventually EVFs will have an unobservable lag time and resolution instistinguishable from an optical VF. By that time, EVFs may be preferred over OVFs because they can offer extra features such as focus peaking, "live view", histogram overlays , etc etc. and without the mirror, higher fps rates should be achievable. (Who on CR would not welcome an 1DM with 24 fps?)

Many may think that OVF will always be superior to EVFs because they are today, but a decade  ago, many also thought that film would always be superior to digital.

I do not think this is driven by declining sales figures as in the OP, but more by ever advancing tech.

Why don't you have round sensors?

Where would you display a round picture?
On your round monitor?
On your round TV?
Would you print it out on round paper?

I could pass it around on facebook :)

mirrorless does not mean tiny bodies.... there is no reason Canon can not make an APS-C mirorless camera identical in size to the 7D or a FF mirrorless the same size as a 5D3... and they can also choose to continue with the EF mount so all those lenses will continue to be valid.

Technology can make things smaller, but ergonomics tells us that the 5D3/6D/7D are at the sweet spot of design size... make it too big or too small and it does not feel right and the controls do not properly fit the hands...

« on: July 11, 2014, 05:47:18 PM »
The slow focus problems may be more lens related than camera related.

I shoot with a 60D and have noticed that some lenses, particularly Sigma and Tamron, are glacially slow compared to my 17-55 or my 70-200... changing camera body without changing lenses may not solve your problem.

I also find this a very hard time to recommend upgrading a crop body as the 7D2 is supposed to be "revolutionary" and none of us have a clue what is coming...

If it were me, I would wait for the 7D2 to come out before adding a new body, and if I were to get a new lens now, I would make sure it is also good with FF.... just in case that's the way you end up going.....
