Lenses / Re: Lens 'resolving power' vs sensors.
« on: September 18, 2014, 09:16:22 AM »
Whoa..... all of this technical talk is confusing me. Let's imagine that canon releases a 36mp full frame dslr,  will that render my "less" resolving lenses such as the 35mm 1.4L, 16-35ii and 85mm 1.2L to doo doo?
I've heard that the 24-70ii and 70-200ii are high resolving lenses and shouldn't have a problem. I wonder what happened on the Nikon side with using the same lenses on the D800 hmmmm.....

The "Legendary" Nikon 500mm F4 flops  on the D800's 36mp.

Rare for anyone else in Canon worldwide too. Still, the year of the lens has got a few months to go...

...and who knows what Tamron and Sigma still have up their sleeves. ;)

EOS Bodies / Re: Canon 7DII - Did you preorder?

I'm waiting to see how the noise at 1600 ISO compares to the 70D.  If it really is a new and improved sensor with respect to noise then I'm in.

Nice piece of work.

EOS Bodies / Re: How does the reveal of the final 7D2 specs make you feel?
« on: September 11, 2014, 02:36:37 PM »
It makes me feel angry and betrayed.  Just kidding.  In reality it makes me wonder if I want to go back to crop.  If it turns out to be a mini 1D X with decent IQ at ISO 3200 and below, I might have to give it a try.  I liked the 7D a lot, but the performance at ISO 1600+ just didn't do it for me.

+1.  The spec tells you nothing about the IQ at ISO 1600.   Need a review to see if it has improved to a useable level.

Lenses / Re: When will we see a replacement for the 100-400?
« on: September 10, 2014, 10:30:37 AM »
Yup, Canon doesn't want to eat their own lunch. Problem is that they're then exposed to others eating their lunch. Canon is never very aggressive here.

LOL.  People who speak of f/5.6 zooms or primes 'cannibalizing' supertele sales are rather clueless.  The superteles are on a whole different level of IQ, are 1-2 stops faster, and have better AF.  Pros who need a supertele generally know it, amateurs often move up from the 100-400L, so that lens is sort of a gateway.  Even with a big IQ boost, a new 100-400L won't beat the superteles.  Canon also prices their lenses to ensure profitability. 

As for 3rd party competition, that's been there all along.  For some lenses, the quality has gone up (though Sigma's QC issues apparently continue to plague them)...as have the prices.   The Tamron 150-600mm is a decent lens, with similar IQ to the current 100-400L (similar in the overlapping range, similar at the long end to the 100-400 + 1.4x).  A 7DII/X with f/8 AF will make the 100-400 w/ TC quite feasible as a much smaller and lighter choice over the Tamron.  The Sigma 150-600mm is even bigger and heavier than the Tamron. 

Will we see an updated 100-400L?  Yes, I think we will.  Likely in late 2015 or spring 2016.  Canon is good at extracting profit from consumers.  So...release a 7DII/X now, the new action-oriented APS-C body will spur sales of the 100-400L.  Some of those who have one already will buy the 1.4x because of the f/8 AF.  A year later, release an updated 100-400 to get people to upgrade. 

It might make philosophical sense to release a new 100-400 along side a new 7-series body, but it probably doesn't make fiscal sense.  The economy isn't terribly strong right now.  Spreading out the launch of 'big ticket' items targeted at the same market segment seems logical.

I totally agree that the 100-400mm is more of a gateway drug to the big whites.  Not going to cannibalize sales, only going to give people a taste of  what they want.

I think you are wrong  about the third party lenses.  The Tamron is 1/2 the price of a 100-400mm plus 1.4x III and only weights  about 330 grams more.  I think Canon has missed the boat with the 100-400mm upgrade.  I would expect Canon upgraded lens to be in the same ballpark price wise as the Nikon 80-400mm.  Tamron is going to eat both their lunches.  It will also eat Sigma's  lunch if the weight and price of the Sigma 150-600  are as rumoured.

Canon can improve the 100-400mm  but I don't think they can make it price competitive with the Tamron.
I already know several people who have upgraded from the 100-400 to the Tamron.
Personally I got tired of waiting for the upgraded 100-400mm and added the Tamron to my kit to replace my Sigma 150-500mm.

Yeah, but this is a third-hand rumor, probably translated multiple times from the original ancient Geek!


There fixed the typo.

EOS Bodies / Re: Are you planning to purchase a 7D2
« on: September 04, 2014, 06:45:17 PM »
An interesting result....

Despite the negativity about various rumoured features, it comes close to an even split between those planning to purchase and those who wont. This might indicate a well selling model.... but of course everything depends on what the real camera is, and unfortunately we will probably have to wait for an official announcement for that.

I find it a bit disturbing that only 7% might buy one after they test it, 31.5% will only buy one if reviewed positively.  While reviews are useful for gathering information, I think making a purchasing decision primarily on a review for something like a camera (or lens) is a bad idea.   Reviewers rarely capture and communicate all of the positives and negatives of a device effectively, and only you can see if feels right for you.

I will buy the 7D2 only if it has better usable iso than the 70D.  I will get this information only once one of the review sites I trust  tests the camera.  Playing with it in a store won't allow me to get this information.   If the noise at iso 1600 isn't better than the 70D then I will probably get a 70D instead.   Why should this be disturbing to you?

The x-rite colormunki display is all that you need.  It will calibrate your display and it costs about $170.  Rental is not really an option as they recommend  regular calibration.  Once your display is calibrated then you need the costco printer/paper profile to use in genenerating your images for printing.  Your Costco's website should have the details you need.

Lenses / Re: Going native at 400mm
« on: July 24, 2014, 06:41:52 PM »
The 400mm f5.6L with the 1.4x converter will work fine on your 5D3 assuming you upgrade to the firmware that lets it focus at f8.
I used the combination for several months before upgrading to a 500mm f4L.

I have  had the Tamron 150-600mm since march and  unless I am going out specifically for birds, I'll take it for the zoom.   

I had the Sigma 150-500mm as well and I agree that it was a dog at 500mm.

Now you are just being silly. The 7DII is a myth, whereas the unicorn is the national animal of Scotland.

I thought the Haggis was the national animal of Scotland. ;D
