EOS Bodies / Re: Disappointed with Canon?

Do you know of somewhere on the web that posts unit sales of dSLRs?  I've always been curious. 



No one publishes accurate sales by model of DSLR's, those sites out there merely get a small amount of data and extrapolate it, which can be extremely inaccurate.

Amazon sells a large number of cameras, and they have a sort of rolling best sellers list, which gives you a idea of what is popular, but, since i don't know exactly how it is computed, take it with a grain of salt.  For example, the D7000 is listed high on the list, so they must be counting pre-orders as sales, because they are and have been out of stock or short on stock.

Ok, I am a little perplexed. Why are we talking about the 16-35, 17-55, or even the 17-40 all of which are good 'standard' lenses when what he needed is an UW lens. In that category you have a limited number of choices ranging from the Canon 10-22, Sigmas, Tamron, and Tokinas that all cover a similar range. The OP does landscape photography so he needs wide. The bottom line is that the 10-22 is the best cropped sensor UW zoom of the bunch with the Tokina 11-16 and 12-24 coming up next and the Tamron/Sigma being strong finishers. Depending on the lens you get, your quality will vary from lens to lens. The quality variation is less with the Canons.

Perhaps, its because he listed lenses in this focal range, and asked how they compared? 

" have a canon 50D and I am considering the EF-S 10-22mm f/3.5-4.5. How is the optical quality of this lens verse the 16-35 f/2.8? Is it somewhat comparable? I have the EF-S 15-85 and I'm happy with the build and quality of it but I need a wider lens for landscape photos at times."

Thanks for sharing your opinion, canonman.  I'm recommending others take a large grain of Salt-with-a-capital-S to go along with your Truth-with-a-capital-T.  I agree with kubelik that Canon includes this feature for a reason.  Just to name one, lots of people rent lenses - would you recommend they rent them for a couple of extra weeks, each time, so they can send them into Canon for adjustment?  Something else to consider is that many people who've sent their cameras into Canon to let 'the experts' clean the sensor have reported getting the camera back with more sensor dust than when it was sent in - what makes it certain that 'the same experts' will do a better job at focus adjustment?

Agreed with a !  I have micro-adjusted many Canon lenses.  While it is true that wide aperture lenses are more sensitive to focus errors, mis focus has happened on standard aperture lenses.

Its quick and easy to do a MF adjust using a tripod and live view.    I would not send in my lenses unless my testing revealed a serious problem.

Too many people read internet blogs and then proclaim what they have read as the truth.

EOS Bodies / Re: Used vs. Refurbished Canon 7d?
« on: December 13, 2010, 11:02:56 AM »
Some people do not like refurbished cameras, they feel that the odds of more trouble are high.  The refurbished Canon cameras do not have a full one year warranty, they have a 90 day warranty.  Used cameras have no warranty at all, so unless you know or trust the seller, there is a elevated level of risk.

Also realize that most used camera buyers are not aware of the Canon refurb camera program or do not have a broken camera to trade in.

Its your money, take your choice.

Canon EF Prime Lenses / Re: Canon 50mm Æ’1.8

This was also with a MK I at f:/1.8.  Autofocus with my 5D MK II was fine even in near darkness.

Concerning "PowerShot The usual upgrades can be expected to start in late January. I’ve received nothing out of the ordinary."
I'm thinking of buying the Powershot S95. Should I hold off for a while?

The S95 just came out.  There might be another next fall.  I did not like my S90 due to its small buttons, but that works well for many.

a question that's been bouncing around in my mind is, are we going to get to some critical point where traditional digital update cycles have a paradigm shift and move into longer replacement timelines, maybe 4-5 years instead of 2-3?

in the first decade of digital camera technology, we saw huge jumps in capability every two years, which warranted tight refresh cycles to stay ahead of the competition.  things appear to be leveling out for all the major manufacturers right now, however -- I know none of the cameras on market can be described as "perfect" but there definitely seems to be diminishing returns with every cycle of updates.

more AF points, more FPS, more or less pixels, weathersealing, viewfinders ... all of these sort of have a max-out point and we seem to be getting pretty close to it.

I'm sure that manufacturers would like this, however, there is always the competition to deal with.  If the competition adds a new model with more bells and whistles, then you have to match or lose sales.  Right now, Nikon has not uped the ante, so Canon is free to take their time.  Introduction of a new model can be a very expensive thing, particularly if it involves a new sensor.

i'm thinking about buying a 5dII - do you think i should wait for the 5d Mark III? (i wouldn't have a problem to wait 3 months.. but if it's going to be more like a year i would probably go with the mark II for now :) ) any thoughts?

No one knows.  3 months, 6 months, 2 years?  Its all just guesses based on past new model introductions.  My take is that the 5d MK II is selling very well, so Canon sees no need to introduce a replacement that would be just a minor upgrade, but cost more.

The rumors of any substantial changes are just the dreams, as are the comments about poor AF performance from those who don't use one.

I've had mine from the first batch that was shipped in late November 2008 and its been great.

I've taken many thousands of images with my 5D MK II and never had a problem with the mode dial accidentally turning.
