EOS Bodies / Re: Canon 1dx vs Nikon d810
« on: August 13, 2014, 01:07:11 AM »
The experiment is flawed, and the photo shown has nothing whatsoever to do with the vague concept of "the D810's sharpness."

The sharpness in the picture is clearly limited by just about every other possible photographic factor other than the D810, so the D810's "sharpness" (whatever that means) is not even being measured here.

Besides, I happen to have a D810, so how is it that my "D810 sharpness" looks different?

(Note: this is definitely not the sharpest example from my D810. It is also flawed and limited by photographic factors other than the "D810's sharpness.")

The difference is your sharpness is partly due to having a very deep DOF, where as the example from the OP is sharpness within a very narrow DOF. The eyebrow is definitely sharp, it's just that the eyebrow wasn't the thing that should have been the focal point of focus.

To compare sharpness you have to normalise to the same size, you can't look at the same 100% enlargement as the Nikon will be enlarged much more.

Reduce the Nikon to the same size as the Canon and then compare sharpness, this is comparing 101.

Agreed, however, the eyebrow is definitely sharp in the D810 shot, where as the eye is just slightly out of focus. That's a misfocus, if you ask me. Even if it sharpens up when downsampled, the eye was the focus target, not the eyebrow.

I'd certainly welcome the demise of that flapping mirror.

So would I, except for the fact that all the alternatives are dramatically worse.

Agreed. A viable alternative hasn't presented itself yet.

Nice shots, Alan and Febs.

For everyone who likes to photograph the moon, you should really try on the non-full phases. There is SO much more detail when the moon is a large crescent, half, and gibbous. The closer it gets to full, the less relief there is to show off all the surface detail. The best times, really, are a few days before through a few days after half, as you get the greatest amount of relief during that period, and the moon is bright enough not to require long exposures (crescents can be challenging, as you often need to use longer exposures....and it's best to use the lowest ISO you can get away with, as DR is still immense.)

Just out of interest, what flashes are you using at 1/1600 sync?

Schneider Kreuznach  has some 1/1600th second sync leaf shutter lenses for the PhaseOne system. They are apparently extremely good...I think the price starts at around six grand for a 28mm prime.

You might find this article insightful:

No, I wasn't interested in the shutter, I have been shooting leaf shutter lenses since the mid seventies, I was interested in what flash puts out a decent amount of usable power in under 1/1600 sec.

Leaf shutters are often held up as some kind of golden bullet, especially here, but they have all sorts of their own issues (I own four) and what people seem to fail to grasp is that flash duration at decent power levels is normally much longer than 1/1600.

As I understand it, the higher sync speed allows you to shoot, with flash, at MUCH faster apertures in brighter ambient light than you are normally able to with slower sync speeds. If you read the article I linked, it becomes pretty clear why people want a high flash sync and how they use it.

I really wonder why Canon doesn't bring eye control back. It certainly seems like fans of the EOS 3 ECF really want it. It would be interesting to have whatever it is your looking at in the VF be focused...that would just rock. I am guessing the system was expensive, at least that's what I'd read in the past...in a film camera, it was probably one of the most expensive things. However in a DSLR, it's just one more expensive thing to add to the mix...maybe it pushes cost over the edge.

As much as I love the idea, eye AF never worked well for me on my EOS 3, or any of the Canon camcorders I used to use back in the day. I'd probably fare better with contacts, though.

IMHO there's a simpler, better way to do it. Of all cameras, the Panasonic GH4 actually comes close to what I'm thinking- if you enable an option buried deep in the menus. It's not ideal, but it's a good start. With a little creativity, one could iterate on it or something similar to design a UI for AF point selection that'd be significantly faster & easier to use than a D-pad, or a joystick, or the cumbersome 4-way controllers on most mirrorless ILCs.

I currently don't have any problems whatsoever selecting the AF point with the joystick. I can move it around without ever taking my eye from the viewfinder. The toughest part is hitting that little M.fn button next to the primary dial...there is probably a more accessible place for that button. But once it's pressed, actually selecting the AF point is not difficult at all.

No built in WiFi?  That kills it.  It's utterly and totally useless.  Heck, I might as well use film!

Not really.  But wifi would have been nice to fiddle with for me, at times, especially when I have it attached to my telescope.

Now, if it's missing a direct print button, then I'm out for sure.   ;)

Hmm. I wouldn't want an unreliable wireless connection as my connection to the camera when it's on the telescope. I image for hours every time there is a clear night, and wifi signals are prone to interruption and dropouts. A dropout would stop imaging dead in it's tracks.

Now, a gigabit ethernet port, that would kick ass. I'd LOVE something faster than USB to use, and a lot of the new high end equatorial mounts are putting ethernet ports in them as a matter of course now, so the whole entire industry could shift to ethernet for control of telescope imaging soon.

EOS Bodies / Re: Canon to Make a Big Splash at Photokina? [CR2]
« on: August 11, 2014, 10:00:02 PM »
Umm...toothpaste? That's where this conversation went? Seriously....?  :o
Wait a second... Big Splash? Toothpaste?? Does this mean that Canon is releasing EOS branded toothpaste at Photokina?  ???  Well if this is the case, then would that mean that the 100D used teeth whitening toothpaste to become white?..

It all makes sense now! Canon is releasing EOS whitening toothpaste to make a DSLR white coloured!  :o

Could this be Canon's response to Nikon's new T810 toothpaste?  It's at least as good as Canon's toothpaste, but it will only stick to Nikon's brushes, which in turn are a lot like Canon's brushes, but softer at the corners.

I think it's gonna certainly beat Nikon's T810 toothpaste, and hopefully, Canon release a new brush with their "dual fiber" technology/more fibers. Or else Nikon will have the edge with their 36 million fiber tooth brush.

They not only need more than 36 million fibers in their brush, Canon also needs a longer shaft, so they can reach way back into the smelly reaches and lift up plaque from the utter depths of the wisdom teeth.   ;D

Would Canon benefit from offering some kind of product similar to the Leica S? Not a "full-blown" MF system to compete with Phase One or Hasselblad, but still something larger than 35mm?

I'm just not sure of the benefit given 35mm sensors now boast amazingly high resolution. The quality of the pixels is what Leica sells in their S body, given its comparatively modest resolution for a MF system. The leap in quality undoubtedly exists in the lenses.

Interesting play on Canon's part...

It's not about resolution, it's about sensor area. For a given subject framing, assuming you frame the same in all cameras, a larger sensor will always perform better. It doesn't matter how many pixels there are or how big they are, all that matters is the total amount of light gathered. Bigger sensor, more light at any given aperture. A MFD gathers more light than 35mm which gathers more light than APS-C which gathers more light than m4/3 which gathers more light than the inch fractional sensors at f/4. Simple as that.

LOL  ;D  Not Islander's one....Dylan's one.

Ah...the conversations got crossed. Dylan's could be a Reddish...tough lighting on that one. The neck is definitely wrong for a Green Heron on Dylan's, though.

That's the one I think it is

http://ibc.lynxeds.com/photo/reddish-egret-egretta-rufescens/narrow-beach-along-kennedy-causeway

Most definitely not that. That bird is different in many respects. Wrong bill color, wrong neck type, does not have the yellow patch at the eye, does not have the same type and amount of varigated feathers along the back, DOES have long, thin feathers off the back, which the Green Heron (and the bird in Islander's photo) do not have, it's legs are the wrong color, doesn't have the white just around the lower part of the eye patch  around the bill, does not have the white streaks down the neck and breast.

Bird identification is a pretty solid science. Aside from a short period of time when birds are juvenile, their colorations and markers are VERY specific. There are far too many differences between the Reddish Heron and Green Heron to mistake the two. Islander's bird is definitely a Green Heron.

No, that's not a Green Heron for sure.

Dylan got the same bird, here

http://www.canonrumors.com/forum/index.php?topic=19270.1095;topicseen

And you can see a Green Heron just above from Islander.

Dunno, looks a lot like a Green Heron to me:

So my answer is, where are the new improved models from Canon today?

Pending. Canon does not iterate as fast as Nikon. That may have put them behind a little, but I think in general, having a longer cycle than a year or so is good for business. It is NOT satisfying to spend three grand plus on a piece of high end equipment, only to have the company "fix" it's issues, then ask you for another three grand a year and a half later. If you read Nikon Rumors forums, that reaction is evident in a lot of Nikon users. They may have the better sensor technology, but that doesn't mean Nikon owners are compliantless.

We cannot really speak to Canon's new sensor technology yet. It's too soon. The 7D II will be the first real opportunity for anyone to see if Canon has done anything on that front or not.

Mackguyver's image reminded me of some of my older supermoon photos. Most of these were from a couple years back, when the supermoon was the closest in 18 years (March 19th, 2011 @ 221,565mi, vs. the 221,765mi of this year). When the moon is full, I don't usually try to photograph it in detail...there just isn't any.

But it makes for great artistic photos, if you can catch it lower in the horizon, behind a thin layer of clouds, or painting a sky full of whispy clouds:



Very nice series....I can almost hear a wolf howling.

LOL, yeah. This one is definitely a wolf moon. :D
