Lenses / Re: Canon EF 200 f/2L IS & EF 800 f/5.6L IS [CR2]
« on: March 13, 2013, 11:04:41 AM »
I'm kind of surprised to hear about the 200 f/2L IS being up for replacement already.  The current model is already considered to be pretty close to optically perfect and has an effective IS system.  I also doubt that it is a high volume lens at its current price, and Canon seems incapable of designing replacements that are even close to the price of current models.

This seems like a bit of a head scratcher to me, although I wouldn't be sad to see some MK I's at reduced prices on the used market.

My thoughts exactly.

And yet I can't stop reading this thread. It's a mesmerizing train wreck in posting form (with little tidbits of good info thrown in).
The petal hood has come in.
Please do take a video of your SLR focusing with that lens hood on, upload it to youtube, and post the link here :)
...and +1.

Well, if you are doing a lot of lenscap work, then you obviously don't want a 5D Mark III for your camera.
^I read this as "landscape", not "lenscap", and I was very confused at what was wrong with the 5d3 for landscape... ;-)

Absolutely love this lens- and unlike killswitch, mine is a 0 AFMA on both ends (lowly 7d doesn't have w/t AFMA, so that works out well!)

First is from NCAA skiing championships this weekend, second is the first shot I took when I got my 7d and this lens, back in early December. Anyone care to tell me how my girlfriend felt about being a model? ;-)

edit: yes, I noticed my watermark on the one from 2013 says 2012.

Back in the day, Mac were a much better platform than a Windows PC for any graphics arts applications such as Adobe.  Today however, it is the opposite.  Adobe's CS6 Mercury engine supports CUDA extensively and supports NVIDIA's Maximus solution.  Abode being OpenGL based means that you get much better performance and more extensive features using admittedly more expensive Quadro and Tesla cards than GeForce cards. 

A PC with a relatively cheap Quadro 600 should render a video in Premier Pro CS6 in around half the time of the current iMac.

Put in card a Quadro K5000 and a Tesla K20 in a PC (this is not cheap) and you will have performance that would require a fleets of Mac's.

Summing up, a single Windows PC configured with a Quadro and Tesla card will give performance a Mac user can only dream about.

This is very interesting.... if true, I will be very interested to see what Apple includes for graphics with these new Mac Pros coming up....

i'm not sure i understand this completely...
on one hand you say "make a smaller DSLR with EVF"
on another hand making a camera with EVF will eliminate the need in mirror box and prism, effectively moving this camera out of DSLR category and closer to large ILC

Not quite- prism, maybe, but you'd still need a mirror for PDAF. And while I'd be open to the idea of an EVF if the right one came along, you'd have to really sell me an SLR that only had CDAF.


Prior Apple Genius here.  Bseitz brings up what seems like it should be the truth.  The reality is though that OS X and Aperture are extremely intelligent when it comes to allocating RAM.  Aperture won't use what it really needs at the expense of other processes to an extent.  It knows that you may flip into something more important, so it won't take what it really wants.

Swap used in activity monitor gives a better indication of whether or not you've maxed out your RAM.

Finally, as someone who has used a MacBook Pro with both 8GB and 16GB of RAM in a similar use case to yours, I noticed a big increase going to 16GB of RAM.  Going from 16GB to 32GB in my iMac wasn't as big of a difference, still a nice little boost though.

At the risk of hijacking the thread, only doing this here hoping for benefit to more people than myself:

I always get confused about Page ins / Page outs / Swap. I used to use Page outs as my indication for needing more RAM, lately, haven't had a problem with it though. I mostly used Page outs because it also gives a bytes/sec readout, so you can tell what you're currently using. For swap, am I correct that it shows what you've used since the machine last restarted? For instance, my swap currently shows 2.92 GB, Page outs 2.42 GB (0B/sec), and Page ins 24.06GB (0B/sec). 3.42GB available RAM. So currently, I have plenty available, but given that I haven't restarted in a few weeks, at some point I did something that required some swap, and that's still showing up on activity monitor.

Thoughts? Thanks for your help!

Disclaimer: I have not really pushed the limits of video editing. I am somewhat of a tech geek, and have asked CS6 to do some 3d renders and high def video, but always playing around.

I've had a really great experience with my 27" iMac. It's a late 2010 model, 2.93 GHz 4core, 12GB RAM, Radeon 5750 w/ 1GB. CS6 works great, although sometimes I come close to bumping up against the RAM I have- so I might recommend 16GB or more. But as far as your current workflow, I think the iMac would do nicely. Two big problems with the macbook pro: screen size, and heat. A friend of mine has the retina pro, and it gets quite hot when working hard. The larger enclosure of the desktop helps get around this. There's also absolutely something to be said for that 27" display: I have both the iMac and a non-retina MBP, and 15" never felt small until I had the desktop.

As far as the PC option, I have to say, I don't know nearly as much, although performance specs are performance specs. If you can get a new i7 processor, at least 16GB of RAM, and a good video card and display, I imagine you'd be happy. Ultimately, that's a question that a lot of people will weigh in on, and you have to decide on for yourself. Would you rather try final cut, or PC-only-3D software? I am a very happy mac user, and would recommend the platform to a lot of people, but there are reasons to go PC, and you just have to weigh the pros and cons of each for yourself.

I dunno, I'm beginning to suspect I have a particularly sharp copy, but I just got a 2x extender II, and mounted on my 70-200 2.8/non-is, I'm pretty happy with the results wide open at 400mm. Autofocus is noticeably slower, and has to hunt a little more, but I didn't notice as much CA on high-contrast edges as I expected, and it's not as sharp as the bare lens, but at least in some quick shots of things all the way across the lab, it's absolutely satisfactory... no IS, but I imagine if you're shooting mostly airshows with the extender, that you'd have a fast enough shutter speed to render that irrelevant anyway.

I'm a little confused... if the 300 end of the 70-300 was limiting, why are you considering a 70-200 or 200 prime, + 1.4x extender? A 2x extender would get you more length... a 200 + 1.4x is only 280mm. I think if the 300 end of the 70-300 felt limiting, the 300 f/4 + 1.4x or 100-400 would be good options. A 2x extender on a shorter lens would be a possibility, but if you think you're going to want that length often, you'll get much better results without resorting to the 2x TC.

Having done a rebel -->  7d move myself (granted, my rebel was an older 400d / XTi) I highly recommend that trade.

I think Canon will put forward an affordable camera in 7D2...~$2500 at introduction perhaps even a tad lower...a price that tracks down with time to ~$2000 or even ~1900 (gasp! WHAT!? NO?....yes!) ;)

This is based on the assumption we are talking about 7D2 and its intended mass market and not the 4D or 3D etc.

Given that the original 7D cycle has stretched a few years now, and the pent up interest to buy is there for original users, I think they have the potential to sell a lot of units...*IF* it is priced right.

IF they miss the price mark...and offer some super-duper camera which is out of reach of many current 7D users, they have a problem... accolades and admiration by few who buy and can afford it and envy and apathy by many who can't... never paid no bills at Canon ;)

In such a case they will have to make embarrassing "Adorama ebay sale" kind of backdoor price reduction (5D3 anyone?) moves to bring the price in line with market forces to move enough units. Bring it down a bit, and they sell more units to easily off-set even the price reduction.

One should expect the 7D "preorder" price to be high (duh! It is targeted toward a certain kind of sap...er...I meant user). Look at the price trajectory of 6D in just the past few months... and it has not settled into its "real" target price yet...give it few more months.

So the intended target price for 7D may well end up being $2000 just few months after release in which case they cannot really pack it with high-end 1DX features in earnest.

Again, we are talking about 7D successor here, not a would-be 4D candidate. Canon is a conservative company. No risky market experimentation or bold moves usually...

So 7D2 will be a sensible camera at a sensible price.

God I hope you're right. I was getting worried I was the only one expecting/hoping this would be where they'd take a 7d2...

What if Canon leaks all these different rumors and uses our comments as a free focus group session?
hahaha I'd be lying if I said this didn't occur to me... great use of Keanu, though.

About the batteries-

There's a big difference between amps and mAh. mAh is milliAmpHOURS, or the amount of current that battery could put out for an hour. That's different from the measure of the number of amps the battery can provide in an instant of draw from the camera...

Edit: Mt. Spokane beat me to it...

This is in line with what I wrote here on a sunny Sunday last June:

Predictions based on generalized long-term knowledge of the history of technology with neither scientific basis nor specific speculation. Intended only to provoke thought and discussion. If you're response is that I'm an idiot, fine, I'll say that right up front and save you the trouble. So...

1. The Canon EOS 1DX (if it ever becomes reality) is the last 1-Series flagship DSLR Canon will ever make. Like the EOS 1V was/is the last 35mm film SLR from Canon, the 1DS will be the last DSLR. Like the 1V it will be around a long time. Its "obsolesence buffer" will be plenty of room for "upgrading" through software application.

2. A new "flagship" version of the APS-C line will be introduced (e.g. a 7D2), and like the 1DX it will be the final flagship of the APS-C line. It also will be around a long time and see upgrades through software. Given Canon's predilection for super pricing I predict it will be over $2500 U.S. And most people who have a 7D today will buy one! It will seem spectacular.

Meanwhile, Canon will lead a transition to new formats that require far less mechanical apparatus than the traditional SLR. I'll leave speculation about exactly what that may be to others.

That's what I said, and I'm sticking with it. The only adjustment I may make is to shift the initial price upward, probably over $3K, hard as that is to imagine.

as long as that new segment they move to after this round of DSLRs still works with my EF lenses, I'm OK with that. ;-)

who knows, maybe I'll "downgrade" to an 80d, if I ever move out of this 7d...

I dunno, this all sounds like it would make a great camera, but it doesn't seem like a logical step from the 7d, at least in my eyes. Don't get me wrong, I see the point of releasing a sort of followup to the 1d series, but integrated grip and price well north of $3k sounds like it should be a "4d" or whatever you want to call it- a 1dV, so to speak. That was is so much of the beauty of the 7d- manageable size and weight, and a very attractive price. Sure, this would be a great camera for sports/wildlife shooters, but it seems to be getting too close to the 1dx and too far from the 7d. If this is really the 7d2 that goes into production, upon the announcement I'll immediately go buy more LP-E6es and another 7d, and be set for a long time...

Also, I can't help but mention the two things that no one else has: this is one of many prototypes, and it's a CR1. So honestly, I'm not too worried about the fate of the beloved 7d line just yet.

It is very interesting and very hard to believe. Canon can be a BIG game changer if it can release such a camera.

I think this would be a game changer IF it comes in under $2.5k. If the initial release price is much more than that, then it'll just be a case of moving the 7d up in the marketplace, which really isn't remarkable. Moving the featureset up and keeping the price reasonable (note I consider $2k or $2100 reasonable, in this case) would be the market-defining move.

Walkaround, usually 85 1.8. I like the smaller size compared to my 17-55, which also suffers from a bit of zoom creep if I walk around with it hanging from my neck. By far the majority of my shots have been taken with my 70-200, but that's usually more a case of "I'm going to a sporting event, I'm bringing my camera", and less spontaneous.
