EOS Bodies / Re: B&H Photo Hands-On With the EOS 7D Mark II

Who or what says you need to shoot only sports and wildlife with this camera?
Says anyone who could save several hundreds of dollars and get the same performance from a 70D if they're not going to shoot sports/wildlife.

If the 7d1 was good enough, the 70d certainly also is - but you have to watch out for hidden traps. Canon removed the spot af from 7d1->70d, and at least when I tried the 70d in a shop I found the af points to be *huge* and think it might be difficult to af small spots with it. Feel free to correct me, but many usability differences don't show up in a quick comparison of core specs.

It is possible that there were two prototypes 7D Mark II, with 20 and another with 24 megapixel. However, Canon would not give for someone to do a review, a camera that was not properly tested to be produced on a large scale.

I'm positive there were more than just two prototypes as the 7d2 seems to be delayed a lot - from a marketing point of view, it should have come before the 70d using the 7d1's af system.

Most of all, with Nikon being at 24mp, it's reasonable that Canon tried to catch up - but probably found that their 24mp sensor underperformed and would also endanger the 22mp 5d3 as a lot of "dumb" Internet tech rankings and quick reviews only compare a handful of core specs like af point number.

Regarding the extra grip, which provide double battery capacity. Does anyone know if they are using the batteries in parallel, to boost torque for faster AF speed? If they havn't, I'll drop the grip and just carry an extra battery, as I have done with my various 5D bodies.
I posted the very same question to another thread here a while ago, and I think it was neuro who answered that it uses the batteries sequentially, thus not paralell :(

To be expected, Canon is quite zealous in guarding the 1dx-only features (faster af speed, af-linked spot, ..., no Magic Lantern). If they trickle down the af (5d3) & rgb metering (7d2) and don't find anything new to add to the 1d, this will only make them stick more to the exclusive features left.

I video my kid swinging her bat at the softball... 60 fps is good enough when I slow it down to 24 fps... but... I definitely wouldn't mind the 120...

The current problem is the speed of the sensor readout, current (Canon) dslrs don't seem to be designed with video in mind but it's rather a later add-on. Having said that, if you're planning to do slow-motion you can crank up the fps for free at least a bit using Magic Lantern's fps override.

A video I made with a Canon 5D markIII, Raw mode with magic lantern, Lens Canon EF USM 50 mm f/1.4.

Very nice, you could also link it to the ML website as they're always looking for good samples.

I hope the upcomping Canon cameras will have higher-iso and moiré-free video like the 7d2 and a sufficient sd card speed to enable raw video (750d? 80d?). It's such a pity you have to spend €2600 to get a really raw-capable camera, it's not like you'd need an expensive lens for video as you demonstrated. Raw video would then become accessible for the masses and people starting off into making movies.

EOS Bodies / Re: Wifi on 5D MK IV?
« on: October 09, 2014, 05:34:39 AM »

If you imagine the 7d2 with a battery grip for extended wifi life, it probably doesn't make that much of a difference though the add-on has awkward cables connecting the two parts.

After 7D II without WiFi I consider it quite possible that Canon is also going to withhold WiFi on 5D IV. They seem to believe they can get away telling us to just shut up and buy their ridiculously expensive and ultra-clunky WTF bricks.

I'm sure Canon doesn't mind 5d4 customers spending another hundred €€€ to get the wifi, but that might not be the only reason:

The built-in wifi on the 6d is "nice to have", but has limited range and draws a lot of battery - making it feel kind of "amateurish". As professionals are expected to use the 5d4, it comes down to neither optics nor portability, but pure performance and "getting the job done". Looking at a full-blown camera rig with flash, bracket, battery pack and a large lens, another add-on probably doesn't matter that much.

people get way to emotional, and aggrevated, when it comes to discussing camera gear!

But only if our cameras have less metapixies and dynamo race than our neighbor's :-p

More equal? ??? I don't know what that means.

You really don't? It's from George Orwell's Animal Farm, a fable about the communist revolution. After the animals get rid of their jailers and start into a bright new era with all animals being equal, it turns out that the top cadres are "more equal", murder their rivals and enslave the tamer animals again. Always a good quote :-)

I'm quite interested in learning more about their behavior. They tend to fly quite erratically so the better I can understand what they might do, the better I can frame up shots or know where to spend time setting up and waiting for the kind of shots I'm looking for. Hopefully it's not all about running and gunning.

I don't know about any literature, I found out for myself what they do - it's pretty regular. For example the "Heidelibelle" types above rest on noon and even retreat into the woods. If you happen to see one there, you can probably point your macro lens only a couple cm away from it and it won't fly off.

The other good opportunity is when they're looking for weeds in the water to lay eggs, they're really busy then and don't care when you come near them (or preferably wait standing in the water where the best spots for their eggs are).

What shutter speed will allow for just a tiny bit of motion blur? 1/1000s or 1/1250s?

I've tried this with my 60d back then with bees, I found it essentially doesn't really matter that much. Even 1/8000 is not enough to motion-stop an insect in full flight, but as with the wings of kolibri they tend to freeze in the air for tiny moments - that's when you have to get a lucky shot. Essentially I wouldn't trade off iso vs. shutter too much, better get a deeper dof for less oof shots - 1/1000 should be enough.

How I hate even the thought of it. Luckily you and a lot out there feel the same.

Of course it's hard to pinpoint in what circumstances a picture was shot - with macro, it's so difficult to capture a part of the environment and show that it isn't in a lab or a zoo.

Take 20Dave's last (linked) shot above, here's a thumbnail: It doesn't seem to be cropped from a natural environment, so how did the animal get there :-o. Before I get excited about image quality, I'd be interested in the story.

One tricky thing is that absolute extreme ETTR can make processing tricky as most standard tone curves end leaving you with poor highlight separation and a lot of stock color profiles are twisted so you can get weird color tints and problems.

This is also an issue with Adobe's ACR process version 2012 which is "intelligent", unlike PV2010 before it.

In my experience this means that a shot filling the histogram left to right w/o having a nice and cozy "normal" structure with a bump in the middle is a hassle to postprocess. The shadows/highlight controls react in a different way and/or are not strong enough, they need to be dialed at least to 11. So you regularly end up tweaking the tone curve which takes more time.

During the day it is easy to predict their behavior, because many of them hunt from exposed spots and come back for rest. So just be patient and study their behavior. You also can predict their flight course and try to shoot them inflight. But that’s much more difficult than BIF. So don’t bother about too many misses here.

There's so much excellent information here so that I find myself nearly at a loss to add anything except +1. With the 100L, I find it easier to use the crop 60d camera for more working distance (or higher magnification at the same distance) - but this only works in very good light.

Be prepared that this is only a fun venture, there are so many high-megapixel "sitting duck" top-notch shots out there and you you probably get the best images from frozen or paralyzed animals with focus stacking, which I certainly won't do.

  • For me the key is to predict where they land to wait for prey, chasing after them is near useless. After some time they might get used to you though or simply rest a while so you can crawl up.
  • The biggest problem is depth of field to get anything in focus except a part of the eye. This results in either slow shutter speeds (= shake, motion blur) or high iso settings (= too little dynamic range for daylight high contrast, noise). The better pictures you want, the less keepers you get...
  • I find in-flight images extremely difficult, my cameras certainly arent't able to track them so for me it comes down to pre-focusing and being very, very lucky

Have fun and let us see some of your shots, here's a thumbnail of one recent of mine. Also attached is the 100% crop with some motion blur on the eye so you can have an idea what to reasonably expect with a crop sensor.

Also, the profile change in LR sounds like a great advice. Never thought of it before.

Few people have, it's unfortunate one of the most important setting is at the very bottom of the list. Unless you rtfm you'll only get to it when it's too late and you have to red-edit loads of old shots with a sub-optimal profile :-\

I would not doubt however that it's possible that these were shot at 24mp and then downsized (and the metadata stripped......) to cover it up!!

Sure, a 7d2 with more resolution than the expensive 5d3, and pigs can fly :->
