A stop can be a lot, however most of the time it is nothing, iso 100-200 is the same as 1/250-1/500 for instance, and few people are shooting portraits with the 200 f2 at 1600 iso and higher out of necessity. In situations where you really are pushing your equipments limits then obviously one stop can be the make or break point.

But realistically you're not looking at ISO 200-100 for indoor sports, you'd be looking more at ISO 6400-3200 (or as you mentioned 1/250-1/500); which IS a huge difference.  And for instances where you do have the luxury of lower ISOs, you can burn that extra stop on shutter speed or stopping down for sharpness/dof as needed.

As for the lens giving an unrepeatable "unique look", well we all know that is rubbish, for a start you can Breznier Method 200 f2 with almost any lens, you can certainly get much shallower dof using the 85 f1.8 and the Breznier technique. Similarly few, if anybody, can actually pick out these "unique look" lenses when they don't know what the image was actually shot with.

For portraits, absolutely. Although you have to go long for the desired level of compression and need to keep an eye on MFD.  And you have to incur the overhead of stitching/processing them.  Definitely worth it for a special shot though.  And if absolute sharpness isn't your goal, arguably, you may even be better off.

The main use case for this lens is indoor sports though, and and you're kinda out of luck there.

At least you have a balanced and realistic and balanced opinion of what this lens is and isn't.  Better than those that insist it's "the one true lens" (usually because they own one), or that it's overpriced junk (usually because they can't afford one).

Me, I greatly appreciate the lens for it's strengths, and I'd love to have one some day.  But I'm not under the illusion that it's the perfect lens for everyone, or for every use.

Very useful information about the AF system at the below link.

Always funny to see people complaining that the new low-end camera aren't focused on professionals users needs. The fact is that both these camera's target audience are amateurs who just what to make a few good looking picture easily. The great majority of them have no idea what are AFMA, DR or other. The thing they will see, though, is that they can get just as good picture from this camera that the last model but it is of smaller size, so it is more portable and more practical for them.
Although some might fell "cheated" by Canon, just remember that it is a corporation; its only goal is to make profits, just like any other corporation. They are making the products they think will sale best, and according to the success of those low-end camera, it seems they are doing a good job in it.

nonsense....

the complains are about that canon sells a camera as NEW that has barely anything new on it.

Car manufacturers do it all the time from model year to model year, especially their bottom line series of cars....  It's a beginners camera... dont get your panties in a twist...

It's a just a Rebel, they come out like clockwork, and the changes have always been minor from year to year.

Ah the EF 200-400 f/4L IS... The worst kept secret and will be the most un-exciting announcement ever.

No no... he's not talking about the 200-400.... he's talking about the 00-400 lens.... obviousl some new super-ultra-mega wide angle lens...

It's so wide it takes a detailed scan of the brain of the person behind the camera and delivers a picture of what they're thinking.

Always carry a tripod ... use as a weapon if necessary :P

A Monopod makes an excellent weapon.  I have never had to use mine, but I have twice had to explain to the person who wanted to rob me that I was holding a metal pipe, and was a poor target.

That's the kind of stupid advice that gets people killed.
The one you don't see is the one that stabs you in the back!

ET

I refuse to be a target, and I refuse to be a victim.  If someone wants my stuff, they had better arrive in force, and fully willing to face death; most aren't, they just want an easy target.  I've got 13+1 reasons I'm not the one they're looking for.

Be aware of your surroundings, be safe, don't act like an easy target.

Video & Movie / Re: Clouds, my first serious time-lapse!
« on: March 16, 2013, 01:50:25 PM »
Set your shooting aperture, depress the aperture preview button then de-couple your EF lens and twist it 1/3rd away from the lock.

Good tip!  Why didn't I ever think of that?

Are you struggling with money at the moment?  If so let me know, I seriously might buy you one.  The thought of you standing there with a stopwatch in one hand and and your other hand on the camera is killing me.

Yeah, that's painful to even think about.  I'll pay for half that intervalometer if you want to go dutch on it.

You definitely get more bang for the buck with a PC.  I don't do video, but here's the base for my new PC I'm building for photo editing:

Shuttle SZ77R5 http://www.amazon.com/gp/product/B007UZO3F6
Intel Core i7-3770 http://www.amazon.com/gp/product/B007SZ0EHE
32GB DDR3 1600 MHz http://www.amazon.com/gp/product/B0068ZWZY0
Crucial m4 256GB SSD http://www.amazon.com/gp/product/B0085J17UA
GeForce GTX 650 http://www.amazon.com/gp/product/B00966IU4M

~$1150

I haven't decided which direction I want to go on monitors yet, probably either a pair of Dell U2410 or U2412M monitors.  Those are about $400 and $300 each respectively.  Or I may go with a single 30".  I'd prefer 27" but I insist on a 16:10 display, so that's not happening.
Bulk storage will be a few 3TB USB3 drives (which are only about $110 each these days).

All said and done I'm looking at about $2k and change, which doesn't get you much in the Apple world.


Thats a solid build. I hope you dont mind, but I may propose a slightly different setup. The thing I value most in a custom built computer is the motherboard. The option to choose from the thousands on the marker make it possible to customize everything to the fullest. I would start with a Corsair 300R/Antec 900 or others depending on your budget. Those cases are optimized for airflow and will allow for the coolest temperatures. Couple that with a 500-750w power supply (depending upon needs). I recently built a computer where I got a corsair 300R and a corsair 650w builder power supply together for $75, but those deals are hard to find. Then all you have left to match the bare bones setup is a motherboard. The best for the price is the asrock z77 extreme4 (or extreme 6 depending upon needs). I promise you would not be disappointed with this setup.

Also, check out the intel i7-3770k processor. For barely any more money, you have full control of the overclocking capabilities. Place a cooler master hyper 212 heatsink on that with arctic silver thermal compound and the temperatures will be unbelievably low.

Whichever route you go, have a great time building it!


I've been down the big, loud, heavy case road before (in fact I'm sitting next to an Antec P182 right now); this time I'm going in the opposite direction.  Small, light, moderately quiet, and portable if needed (without a sherpa).

Site Information / Re: My previous account just disappeared
« on: March 08, 2013, 10:07:03 AM »
I know we periodically purge old accounts as there are tens of thousands that get created during each contest, post once, and then never login again.

We'll also sometimes get a spammer that will create thousands of randomly named, or sequentially named accounts, and then abandon them once they realize they're useless since they can't post links until they've reached a certain post threshold.

Mark 5D Team III (if I'm remembering your old name right) and mreco99 don't show in the user list so they were deleted.

EOS Bodies / Re: Bodies and cell towers?
« on: February 26, 2013, 11:02:44 PM »
If you do decide go, just stay as far away from the antennas as possible, and be mindful of the inverse square law.  Your exposure (and that of your equipment, but you can replace equipment) increases exponentially (I=1/d^2) as you get closer to the source. So for example, moving from 10m to 7m doubles your exposure, as does moving from 1m to .7m.  Conversely, moving from 10m to 14m cuts your exposure in half.

(awkward photography analogy follows, abandon all hope ye who enter here)

If it helps, think of it in terms of f/ stops.  Your starting point is f/1, reduce the distance (focal length if you will) by .7 (sqrt2/2) and you're at f/.7 and your exposure doubles (plus one stop), increase the distance by 1.4 (sqrt2) and you're at f/1.4 and your exposure is cut in half (minus one stop).

So say you want to reduce your exposure by 4 stops (1/16th the exposure), four stops from f/1 is f/4 so you want to be 4x farther away.  Six stops (1/64th the exposure) would be f/8 so eight times farther.

If that's confusing, just ignore it.  I explained it poorly, but it's the exact same law that governs both (inverse square law).

"little metal screw port that I’ve never seen anyone use…"

What the heck is that anyhow?  It's on the 430EXII as well.  I've always wondered when I notice it there, but never enough to actually look it up.

EOS Bodies / Re: 7D Mark ii with WiFi/GPS or Without?
« on: February 25, 2013, 12:02:46 PM »
I think the GPS is a useless addon, provided you have a smartphone + an inexpensive appli like GPS4cam. It offers IMO the same benefits of an integrated GPS. I'd rather like Canon focus on photographic specs rather than these useless peripheral specs, that cost a lot for a very weak added value. The smartphones HAVE a GPS, we have a smartphone always with us, bar.
About the WIFI, this could be differerent, but there is too a dedicated grip... So ? I really do prefer high iso performances for less MP, weather sealing, and a lower price... I'm maybe old fashioned ?
Disagree
I do not belive that an in camera GPS is going to add a lot of cost to the camera. I'd rather have it in camera than pulling out the smart phone, capture the GPS coordinates, identify the image to add the coordinates in post process sounds like too much of a hassle. I subscribe to the idea of have everything but give the users the option to turn them on/off.
+1
please correct me if I'm wrong on this one, but the camera will have a 'true' GPS, meaning a GPS that will function on its own, whereas a smart phone only has the aGPS meaning assisted GPS where it will need a Wifi connection or 3G connection to be able to obtain its position. + the extra hassle of having to connect it to the phone and all that annoying stuff that won't work properly anyway, no I'm not a fan of having to rely on my phone and in this case some home cooked app too much.

The problem with GPS without A-GPS is how long a cold start takes.  The transfer rate from a satellite is extremely slow, and even though it's only a couple kB it can take quite a while, and only then can it attempt to acquire a lock.  A-GPS has the benefits of being able to download that data from a faster source, and having a rough estimate of current location so it can determine where it is way faster.
Cold start may take longer but I'd rather have it in camera than another device that I have to pull out and go through the hassle of tagging them in PP. At some point someone needs to take the initiative of including them in Semi Pro DLSR's and that's where further progress can be made with faster locking on to the coordinates can be achieved. A good example is Canon 600 EX-RT speedlite ... yes there are some AF issues, but unless the RT was not integrated by one of the big names, there would not have been much progress in this area.
I subscribe to the idea of useful new technologies being integrated into products that can benefit people ... at the moment I see WiFi and GPS as very useful features for a lot of people, especially if the user has the option to turn them off.

I agree completely, the more features the better.  I would just prefer that features that may impact reliability be deployed with extreme caution to "single digit" bodies.  I don't think WiFi of GPS would impact reliability in any appreciable manner (excepting the occasional "battery died because I forgot to turn GPS/WiFi off"), things like swivel screens still worry me though.

Perhaps my fear is unfounded; I never had any problems with my 60D, nor did I ever hear of anyone else having problems.  But I also literally never used it, and haven't missed it one bit on the 5D3.
