EOS Bodies / Re: Canon to Make a Big Splash at Photokina? [CR2]
« on: July 31, 2014, 06:05:37 AM »
I really do not expect from Canon something super new or super mega new technology :) Take a look back to history: I remember all big expectations related to 6D. There were many wishlists but in reality Canon produced significantly crippled FF camera, which AF does not even match old 7D :)

Now I really expect that after 5 years Canon will launch 7DII, which will have 70D sensor, slightly more megapixels (expect 24 MP), slightly higher FPS, GPS and WiFi. That's it :) Do not expect significant revolutions in sensor. If there were such revolutions, there would be a leak of information already. For example, Sony announced curved sensor technology, which will be implemented in their future models.

Canon made revolution  few years ago. Currently it is a stagnant company, which still focuses significant aattention to dying P&S market. Product cycle for semi-pro and pro products is very long and shows that Canon does not sufficiently invest in R&D as other companies. Canon started loosing in the following areas:

1) Mirrorless market - they loose to Fuji, Olympus, Sony;
2) Sensor technology - loosing to Sony;
3) Lenses - starting to loose to Sigma and Tamron as these 2 companies started producing high quality lenses, which match or in some cases exceed qulity of Canon lenses (e.g. Sigma 50 mm 1.4 Art, Tamron 24-70 2.8 VC) for affordable price.

From financial perspective Canon is doing quite OK, even better than other companies, as they still have big loyal customer base, however, in technology companies if you loose momentum you can loos all business very soon.

I definitely think it's reasonable to expect a major improvement in sensor performance, for all the reasons you specified.  Their architecture is old and they are getting beat by a bunch of other manufacturers.  Members here have detailed Canon's deficits while also detailing the changes Canon could make to improve their sensors. 

Canon has to at least match their competitors if they are going to stay relevant over the next 5 years.  I'm interested to see what this 7DII brings, if only to see what the 5DIV be able to provide.

Just as I'm trying to justify an upgrade to a refurbished 5DIII, this rumor happens.  I'll definitely have to wait and see what the 7DII brings.

I expected a false 7D mkii rumor for April fools.  That would have really gotten a rise out of the community.

EOS Bodies / Re: Canon's Plans For NAB 2014 Next Month [CR1]
« on: March 20, 2014, 01:54:31 PM »
If one of those camera bodies is a Cinema EOS product, the other one might at best be a 7D Mark II? I must admit that I am highly pessimistic about this mysterious second camera being the long-rumored high-MP 1D-style camera. Perhaps it is going to be the year of the new camera body I won't invest in. :-\

I doubt it will be the "7D2" or high megapixel anything. It will be a Rebel. I seriously doubt we will we anything exciting from canon this year.

D

All the facts would behoove me to say otherwise but, so many people have made this arguement in the past and been wrong.  I will say that Canon would be making a serious mistep by not updating the 7D this year.  Speaking for myself, I'd forget Canon's crop format and just buy a 5Dmkiii and be done with it.  Although, maybe that was their plan all along.

The difference with o-rings & gaskets and the like is they are not at wearable joints. They are put in place, and they stay in place, and there is no wear on them. The most worn seals in a DSLR are the seals around the buttons, underneath which is a full seal that separates the button itself from the electronics inside.

My point is that an articulating screen is something that will constantly be pulled out and put back, on a continual basis, over the life of the camera. The joint there is going to take a lot of wear (especially if it's one of those swivel joints.)


I am aware that it's been done. I would also be willing to bet that Olympus has encased the ribbon itself in the seal, rather than breaking the seal to allow the ribbon through.

I'm not familiar with the ways that Canon or Nikon weather seal their cameras.  However, O-rings (but not gaskets) have and continue to be used to seal joints that move.  You can find them on rotating and reciprocating machinery such as pistons, shafts, etc.  The O-ring design itself isn't innaproporiate for such joints per se, it's that you have to pick appropriate surface roughness and O-ring hardness for the taks at hand and for the surfaces that form the mate.  It's certainly mechanically possible to design a joint with a ribbon cable that is weather sealed, to whatever specification Canon builds it's camera bodies to.

Whether such a solution is appropriate and/or cost effective for a DSLR designed for a specific price point and performance level is another matter.  I think we are generally in agreement that a moving screen probably won't be included in a weather sealed, sports-focused body, for obvious reasons.

EOS Bodies / Re: EOS 7D Mark II Announcement in Q2 of 2014 [CR1]

After all this time, I would expect the 7Dmkii to be a vehicle to introduce new sensor technology to the market.  It's the only reasonable explinatin I can think of for the time that has ellapsed between the 7D's release and now.  I'd almost say that Canon has to release a body with a drastic change in sensor technology, if they are going to compete with Sony and Nikon. 


If they just slap some derivative of the 70D's sensor in the 7Dmkii, I think a lot of people are going to ditch their Canon bodies.

I'd like to see how Sigma and Tokina are going to deal with this.  My 11-16 and my 85/1.4 are both lenses and, I'd hate for them to be made unusuable.

Here's my guy

What a beautiful dog!!! And really good! Our guy can't seem to help "investigating" a lens when you try to shoot him... it's something we're working on... :)

Thanks!  Yeah, he learned to just sit still when I point the camera at him.  He learns fast!

Such a good boy!

I am sure you said the following before shooting...
"Sit. Stay! No!! Don't even think about it!"

Or I may be spitting in the wind...
 :)

He actually sits down as soon as I point the camera at him.  That's what happened when I took this picture.  He just sat right down and posed.  I couldn't believe it.

Any commentary on the  auto-focus performance?

EOS Bodies / Re: Canon EOS 7D Mark II Spec List [CR2]
« on: February 19, 2013, 11:03:20 AM »
"The Last Camera Syndrome" article really applies here.  These specs are all nice but, none will persuade me to buy the 7D mkii, over my 7D.  All, except for one.  If this new APS-C sensor really does have, at the least, 5Dmkii noise performance, then I will strive to purchase one.  The problem is, I seriously doubt the sensor will achieve such performance, even with superb noise reduction software and resizing. 

One can only hope.  If not, my 7D will remain a prized possession.

many new customers will nevertheless enjoy the better features.

10 FPS with an 61 point AF system..... mhm... that sounds delicious.

They certainly will.  I was only speaking from the perspective of someone that has a 7D.

Canon EF Zoom Lenses / Re: Canon EF 70-200mm f/2.8L IS II USM

Nice panning Jon.

Would have been even better with the car on left side facing the open frame of the shot. Rigth now that abrupt ending is a bit distracting.

Thanks K-amps.

I was actually going for panning shot with the car on the left side of the frame for most of the event.  Unfortunately, I wasn't able to produce a good shot, for a number of reasons.  This one came out the best, IMO.  Next time I go to a track day, I will definitely give your suggestions a "shot".

Shot this at a track day a few weeks ago.  It's my favourite picture from the set.
