Lenses / Re: 300 f/2.8L and 400 f/2.8 at f/2.8
« on: May 24, 2013, 10:05:07 PM »@PBD,
They keep coming loose. I cannot make them stop coming loose after I shoot all day and then take off the camera. I cannot keep combating that.
That sucks bdun....did u buy it new or used?

Speedlites, Printers, Accessories / Re: Canon 1.4X III vs Canon 2.0X III
« on: May 24, 2013, 08:49:30 AM »I agree with Neuro the 2XIII works great on the 70-200 II if you can live with F5.6 wide open. Sweet spot with the combo is around F/8. Note also that the AF speed drops...not by a lot but it is noticeable. Birds in flight can be a challenge for it but not impossible. You wont be happy with the reach using the 1.4X. Where the 1.4 comes in handy is when you are using the Large tele's 300MM and higher.The 2x does well on the 70-200 II.
Eastwind nailed it...my thoughts exactly.

Speedlites, Printers, Accessories / Re: Advice on 1st flash
« on: May 24, 2013, 08:47:10 AM »Im looking to purchase my first flash unit and looking for help and suggestions. I currently own a canon 60d, 17-85mm ,50mm and the 75-300mm. I mostly do travel and outdoor photography and I'm not 100 percent sure how i want to us the flash yet, I just know I hate the pop up flash. My price point is right about 275, so that would be enough for the 430ex II new. And I was looking for thoughts and opinions on if looking at older used ex flashes would be useful. Want to get the best bang for the buck but also get I flash i will not out grow to fast. Thanks for the imput
Another vote for the 430 exii. Great flash, and as others said, if you upgrade someday you can still use it as a slave.

« on: May 24, 2013, 08:34:50 AM »i have a 500d and im thinking of upgrading to a new body but should i buy new glass instead
I had to read your question several times.....and after considerable thought, several google searches, and a phone call to a fellow photog, I've figured out the answer to your question......"maybe"

Whew...that was a challenging one

great action...nice capture!

1D X Sample Images / Re: Any Thing shot with a 1Dx
« on: May 22, 2013, 01:50:55 PM »Just upgraded to the 1Dx from the 5D3, I am just learning how to use it. On the plus side I am getter bigger biceps too. Here are a couple of images that I shot the other morning with the f1.2 50L and the 600EX-RT for fill, the surfer at the shower was @ 2.8/1250/iso 400 and the girls were at f5.6/2000/iso 400
congrats on the upgrade, and welcome.
the 1dx is such an awesome camera to shoot, enjoy!
nice beach shot....love the "chuck taylors" that the girls are wearing.

EOS Bodies - For Stills / Re: 1DX and 5D3 RAW files
« on: May 21, 2013, 12:03:49 PM »Certainly, let me use an analogy which might help. Lets say you are recording a violinist onto a tape recorder using a high quality tape. When the violinist plays softly you have to amplify the signal to increase the volume. As you do so you also increase the noise from the tape. Maybe the violinist is playing so soft that their sound level falls to the point where it's difficult to tell if it's a violin or tape hiss (noise). Depending on which tape you use (high quality or cheap quality) and what equipment you are using (radio shack tape deck or Yamaha digital tape deck) you will have more or less noise when recording that violinist at the same recording level.
This also holds true for image sensors. When the brightness is low such as in a shadow or low light situation the photon levels are so low that they are mixed with noise. Depending on the sensor and supporting backend electronics there may be more or less noise. Amplification, same as with that tape deck, amplifies not only the photons but also the noise level. Higher quality components (better sensor, larger pixels, better amplifiers) can all contribute to less noise compared to the signal and more DR in the shadows.
You absolutely cannot compare sensor IQ without also considering the supporting electronics used in processing the signal. Even if the cameras use the exact same sensor, different electronics on the back end will affect the IQ. There are a lot of different points to consider. What causes IQ differences in 5D3 and 1DX may be different in other models depending on the generation of support electronics also used.
Remember also that the image as it hits the sensor is still analog. It's not converted to digital until after any amplification has already occurred.Failure of the amplifier to pull photons from the background noise.
Please explain what you mean by this statement.
this makes sense eastwind...and i think somewhere in the supporting electronics/advanced circuits/design lies the specific answer to bdun's question.
one question though...if "better quality components/circuitry" supporting each photosite is so critical, then why does my old nikon d7000 (for $1000) have significantly better DR under iso 400 compared to a $6700 1dx when the "supporting parts" are surely of lesser quality.....does it all fall on design at that point?

« on: May 21, 2013, 11:10:51 AM »Some of mine. Went to the local zoo. Just testing my recently acquired Canon 2x teleconverter III with my EF 70-200 f/2.8L II. Gotta give you all a heads up that my shots do not come anywhere close to Gary Samples' and eml58's shots...composition and capture...theirs are just brilliant, jaw-dropping, and most importantly to me, inspiring. Thank you both for sharing your images with everyone here.
Not taking away from everyone else's images...just that these two gents' images are what keeps me coming back to this thread.
hi dwight...how's the 1dx treating you?
i like your second shot of the gorilla with the plant on his face....i like his expression!
remember when we were talking 6 months ago about counting actuations up to 1000, well now i'm somewhere closer to 30k lol...how about you?
lovely form of the stones. Looks like it is my "I like it better in B&W" day.
