Lenses / Re: Canon 400mm L 5.6 .. So what's changed in 19 years?

thanks for the replies and my statements were only examples about the glass or the coating as sort of a reference.  Assumptions welcome but I was seeking more absolute, factual information if at all possible.

Lenses / Canon 400mm L 5.6 .. So what's changed in 19 years?
« on: July 05, 2011, 07:48:19 PM »
This great lens first released in 1993 is currently still part of Canon's lineup and tack sharp.  It has USM but lacking IS as most of us know.  I called Canon support (3 different reps) and no one was able to tell me what exactly has changed/updated/upgraded on this lens since 1993.  It would seem logical that some components have been upgraded or possibly the coating but not necessarily a feature accessible by consumers.

Does anyone or can anyone shed any light on the 19 year time line for this lens?

PS one thing Canon support did state is that the lens is "drip and dust proof" which debunked a statement I had found on another web site.
Thanks in advance

Portrait / Re: Let There Be Light!

"Second shooting" is a common method that wedding photographers employ to make sure nothing is missed on a wedding day. It involves the principal photographer hiring an assistant to photograph with them. Basically two photographers at one wedding.

Lightweight/Starter portrait gear? A good starting point would be:

Umbrella Bracket
Shoot Thru/Reflective Umbrella

You can use your 7D wireless commander to trigger your 580EXII,  but I would consider investing into a wireless trigger system. Once you're comfortable with one light, you can move into two light setups. Most of the Strobist 101 seems out of date, but its very much a good starting point for reading. Speaking of reading, if you want to learn more about light and off camera flash I recommend:

Light: Science and Magic
The HotShoe Diaries

Very familiar with the wireless on the 580EXII - really enjoy that option especially when in manual mode - can get some cool shadowing effects.  I took a look at the books and see there are various versions of Light Science and Magic.  I would presume you mean the 4th edition?  I saw several on amazon  I appreciate the response and tips on items to acquire

Good post of examples - I need to explore that DxO program again.  I've been using a WhiBal card and don't touch the WB in post at all - it's usually dead on with florescent or tungsten light much like what you've show in your sample images

Good thing you got hit with a Canon, I heard Nikons are worse :)

I've been through your trials and tribulations and know first hand an excellent inexpensive solution.  I would skip using the preset WB's in the camera - they are all inefficient except possible the AWB in shaded outdoors or with flash - I had decent success with that .  Don't waste time on the color temp settings unless you have a Kelvin meter for accuracy and they are not cheap. For indoor without flash a White Balance card is essential

Here's what you may wish to consider:
1)get a whibal card - the one I use is by Michael Tapes at:  http://mtapesdesign.com/  the 36.95 one is probably your best bet.  In AWB take your photo, then Set the photo as the Custom WB choice and your done.  If the lighting changes repeat above steps.  Note:  this card offers more capabilities so be sure to read his tutorial.
2)And Shoot RAW, not JPG as JPG pre-bakes all settings into the picture.  Shooting RAW will let you choose the white balance eye dropper in DPP.  So you load your RAW photo with the WhiBal card, place the eye dropper on the WhiBal card in the photo, then apply to all photos from same session.

Hope that helps.

I do this all the time and the colors are dead on.  Also note, if you shoot RAW, there's already a JPG embedded in the RAW file.  The RAW is your Digital negative and the same benefits apply as if it were a film negative.  You always have the unaltered original.  I've played with the camera's color balance settings and that helped a bit but still to get accuracy nothing beats a a good white balance card.


EOS Bodies / Re: Ai Servo in low light
« on: January 14, 2011, 04:00:54 PM »
Though this response is related though I won't touch the AI Servo as Neuro already covered this, in using the MP-E 65 yesterday without the flash at F11 it was complete darkness both in Live View and VF.  As soon as I mounted the MT 24EX macro flash in E-TTL I had light in Live View and was able to focus.  I would imagine the same would be true with the 580 EXII or similar E-TTL flashes so that in fact that may aid your situation especially if in Live View as I was able to at the very least manual focus in low light.

Most L lenses have quiet focus.  Besides, you really need a separate mic / input system when filming on DSLR

Indeed I would agree.  The Zoom H4N is an excellent choice with a cold shoe adapter to sit on top of your Canon Camera or it can sit on another tripod or even mic stand to keep away from the USM sound.  In only wish there was a way to have the live mic's of the Zoom H4N override the build in mic vs. doing an audio sync afterward with Premiere or other software.  Although not that hard to do, just extra time

Just make a personal account with a fake name and fake pic. Lots of people are starting to do that!

I agree.  And if you do, call yourself Frank Canon, like the old TV show from the 70's less the 1 N in Cannon of course.  ;D

Surprising, out of all these posts a 580 EXII flash was omitted.  The built in flash is rather meager on the 7D or others with built in flash) and I use it seldom as it can overwhelming and provides minimal flexibility.  You can really get some well lit photos outdoor or indoor with this flash and it should not be omitted with that size budget.  A lot of folks are fearful about flash but this flash could make or break a potentially good photo.

The 7D is a great choice especially with 5K total budget.

The best she can do is read read read and ask a lot of questions as there is much to learn on what all is being proposed

Wound up watching that whole video thanks for sharing - there were some good reminders in there especially on AF modes in which I tend to lean on center focus more so and perhaps should not.

Macro / Re: Canon MP-E 65 1x-5x 2.8 Macro Lens example photos
« on: January 07, 2011, 10:33:19 PM »
Taken with Canon EOS 7D, MP-E 65 F/11  1/100 @ 2x magnification.  Used Canon MT 24EX Macro Flash.  Flash set to Manual.  "A" flash @ 1/2 and "B" flash @ 1/64 positioned at approx 270º on macro ring.  No diffusers.  Hand held.  No post processing - taken as is.

Great piece of information.  I never saw that blip on AI Servo for Macro.  There's no listing in the 7D LCD with respect to a name called Macro Ai Servo (I have 100mm on now with Ai Servo in place) but I would assume if you are in AF with AI servo on, it just kicks in - there's no menu listing per say.  for some reason I can get in closer to the subject in Manual then with AF spot metering.  The lens can't focus closer then say about 4 or 5 or inches in AF (I forget what the min. focus distance is)

Correct on the trade off 1.6 with the APS-C vs. FF

PS - if you recall where you read that info please send it along - thanks for the help.  You def. know your stuff

You are right about all you say.   I had forgotten about the 2 stop vs. 4 stop with macro despite its a hybrid IS and sure, 2.8 is certainly not suffice for all situations especially in greater need for DoF.  Have you tried using Hi Speed Flash sync with the 24EX?  or when you shoot are you in manual mode mostly ?

Ok, now I get the reason for no vignetting - thanks for that.  I did notice the narrower barrel at the base of the lens so the 58 to 67 as you say has no bearing.  Good to know.  Flake said he was tired of getting a variety of macro rings for each of his lenses that might warrant the 24EX.  That's one of the main reasons he got the Dual Macro Flash Holder.  of course it provides a greater amount of flexibility however he stated its a bit cumbersome to carry.

I am thinking of putting the camera (7D) in AI Servo or AI Focus full time this should help mitigate that moving subject in the wind syndrome

All these options are good but there's so many options one can get easily overwhelmed when the moment calls for the photo.

Neuroanatomist:  I had a hunch you were going to say all of that.  And follow each of your points / reasons for the 58C and 67C though one question remains to be answered:  with the 67C stepping down to the 58mm Macro 24 EX Flash..any vignetting or other issues that might occur while stepping down?  As I've got the 100mm IS USM L 2.8 and don't see much need for a flash (at least at this point) unless you feel its imperative.
