i'm happy to hear constructive comments...positive or negative.  i'm always open to hear different opinions.


Nice, I never see owls in the daytime down here.

Hi Carl.
If you want pheasants just come to the Isle of Wight, trouble is they are mainly squished on the road, they have no concept of vehicles on roads at the best of times but it is the thinking with the small brain season so they are even less aware of their surroundings at the moment, one tried to get under my van wheels yesterday, not content with running in to the road it then started random acts of dithering left then right then stop then.... I missed him, but he tried really hard to get hit!

Really great pics from all, thanks.

Cheers Graham.

Excellent works, guys! Thanks for posting them.

And for something aerial kung-fu. Or taekwondo, if You like that better...

Great, don't see enough pheasants...I wish we had them down here.  The wings spread one is the best.

Thanks for the suggestion, at the moment I can't afford to travel abroad.  I know what you mean about things in the road, I hit a deer, or rather the deer hit me last week.  Oh well, more food for the coyotes and vultures!

I'm not sure I could work under those conditions! 
What does that mean? ;D  :P ;D  :P ;D  :P

Haha, let's just leave that to the imagination!

The stars and the moon are still out there, even in the day time. I think Erik was trying to add a little atmosphere to his journey of heading straight up into the sky!

No need to pile on me, I already clarified my point, but you didn't read it.

Lenses / Re: Canon 400mm DO

Canon's own MTF charts show the 300mm f/2.8 II + 1.4xTC III (bottom) to be significantly better than the 400 DO (Top).
Just checked Bryan's TDP comparison: the 300 at 420mm is distinctly sharper


Well, I did too, and it's not "distinctly sharper" except in the extreme full frame corners.  I would say "somewhat noticeable" on the full frame borders, and "not much different in the center".

What about Canon's own MTFs? Have they got it wrong showing the distinct superiority of the 300 @ 420mm?

Yes, yes they got it wrong, because they just did, ok?  They can't draw their own charts...Let's not get silly Alan.  Look...I believe I originally said the 300 + 1.4iii combo was "not that far ahead" of the bare 400 DO, or something to that effect.  Their MTF chart shows the 135L as even softer than the 400 DO, but the one I own, is not soft at all.  Why would that be? 

In any case, if you must defend the 300 ii as if it is your child and I'm attacking it or something, go ahead.  But just know that's what you're doing.  Frankly if your 300 were your girlfriend it would have already whooped your ass for cheating on it with the Tamron!!  How do you like them apples?

It doesn't change what shows on Bryan's test...in the center of the image, anyway.  Like I said, by the borders, and especially corners, yes the 400 DO is quite bad, wide open (and even closed down a tad).  But it's a DO, designed perhaps 20 years ago.  It's not a terrible lens given this, especially if it can be bought for $1000 or more, less than the new 300 f/2.8 ii (either new, used, or refurb...but I'll admit not many are out there).  And the 400 is a pound lighter.  The 300 is the more versatile lens overall, and performs better overall...but you pay for that.  It doesn't mean the 400 DO is not worth owning and using, if someone wants lighter weight and doesn't mind the slower AF and lower performing IS...yet still wants f/4 at 400mm.

Canon build both lenses at the present time, and they have not stopped production of the 400, that I'm aware of.  Are you calling them fools for doing so?  I think you are...and they (yes the whole company) want you to step outside and discuss it in the street!

Here's another real-world image taken with the EF 400 DO IS, and 1Dmk4, handheld, S/speed 1/5000sec at f4, Iso 500, and a downsized image for web with ACR and CS 6.  Cropped to 2 mpixels from a 16mp original.
And I checked out your cardinal at very high iso Carl, in the BIF thread, amazing results that the sensors can produce at such high sensitivities.  Think the highest I have shot at in the field is iso 10 000

Nice work on this one too!  I liked the 1D4 a lot when I rented it, it had amazing speed.  I much prefer the noise performance of the 6D, though.  Yes, I didn't venture too far out in the field for those shots, I was inside my house.  It was pretty dark for the cardinal in flight about to land on the sill.  I would prefer to shoot wide open with such a fast aperture lens, but it's very hit or miss, getting the bird in the plane of focus while it's flying toward me at almost mach...lands...eats its seed...is gone again, sometimes all this in the span of about 1/3 of a second.  So I wind up closing down more and more to try to get a bird that is not "bird bokeh"...!!

Hey Don Haines...One of my dove shots, also shot through glass.

Have you seen the new DP2?  They claim up to 39 MP...

I have and I'm waiting for the reviews, I think I may get one if the results are good. 39 MP are realistic... of course you just have to get rid of the context "pixels" just by x/y Resolution. The Details of a FoveOn (@lowISO) are outstanding above a Nikon or even a Pentax 645D!

F.e. (picture from dpreview.com):

This was the first sensor which really catched my attention after buying my 5D back then. Everything else is just "evolution" here and there, half a stop more Dynamic, more resolution, ISO25600. Hooray, you invented the holy grail. Nikon bla, Canon bla... everything no real leap. A 5D is still awesome and able to serve my needs. The sigma is again something worth time spending with.

Their stated pixel dimensions don't make sense, unless the sensor is not a 3:2 aspect.  I enjoyed the generation 1 Foveon a lot.  Even though it was only 4.6 MP, it easily scaled to 25 MP, still looked sharp at that resolution on prints at 300 ppi.  TDP and others reckoned the actual resolution was 14 MP, but I feel like it was a bit more (at least below ISO 200).

In the future I hope Sigma make a full frame DSLR with a foveon sensor, WITH A CANON EF MOUNT...rather than a Sigma mount.  That way it could use all lenses, rather than only Sigma's.  And if they make another crop sensor DSLR first, with the new DP series sensor, I hope it too comes with an EF mount.  More people would buy Sigma's cameras if they at least offered having an EF mount as an option.

Erik, who is the client, or clients, for these shots?  And your little foray into storytelling isn't too bad, but the part about climbing into the stars and moon, when it's daytime, doesn't quite make sense.

Carl, I shoot for a number of magazines and my work is also used by aviation book authors and publication houses. Without the support and accreditation of these, none of these great experiences would have been possible - well at least not for me anyway.

And are you trying to tell us that the moon and stars do not actually exist throughout the day?  ;D

Great story Erik!  Love the shot of the A-10.  I'm guessing you shot it out the back of a C-130 :)

You got that right! Taken from the ramp of a HC-130P Combat King to be exact, the dedicated Search and Rescue variant of the C-130.

Haha, well you can't see the stars during the day...maybe you can at high altitude.  I was just saying it was confusing because it was making me think your flight initiated in pre-dawn hours, but it didn't...did it?

I've seen Jupiter and Venus during the daytime, at least on a "cobalt blue sky" day, easier with binoculars than the naked eye, though.

And it's a shame the A-10 is going the way of the dodo bird, and NASA's Constellation program for that matter.  What other goodies can the current leadership ruin for us?

"Crane or Ibis?"

It belongs to Stork family of birds.



Ah, I should have known, thank you.

Hi Carl
To answer your question, I have attached a downsized version of the 22mp original frame of the bee-eater image.  I posted the deep crop to show the IQ that I got from the EF 400 DO, as it can be better examined in that way, as per AlanF suggestion.
It is not quite as crisp at those distances/crops as an EF 300f2.8, 4002.8 or 500 f4 but still pretty decent.
If Traingineer wishes to see more real-world samples from the EF 400DO I can share others, some in extreme low light, and also some birds in flight...
Hope that helps

Thanks Grant.  The amount of crop looks like less than I first thought.  It's quite nice results, I agree...and I'd definitely like to see more samples.  I know I'm not the original poster, so if I could see them some other way, let me know.  I posted in the "bird in flight" thread from my 70-300, at 300, even more cropped than that (and only starting at 20MP)...at ISO 1600, and it didn't look too bad (and I'm pretty sure I was shooting through a window too).  Nobody seems to have liked or noticed it though!  (the squirrel eating seeds in a bird bath, while a cardinal flies below him!).

Had 100mm macro mounted on my camera, just made use of the unexpected opportunity :)

Crane or Ibis?
