Mixing an Einstein 640/w Cyber commandeer with 600 EX RT's and ST E3 RT.

So, Just got my first Einstein and went the cyber commander route as I want to add more lights as time goes by. At the moment I also have and use 3 600 ex RT's and a st e3 RT. Will I be able to plug the Cyber commander into my PC port on camera, and have the Canon RT transmitter (Plan on using a 600 as a Hair light) attached as well and get both to fire? or do I need to buy one of the Paul C Buff receivers? I can't find reliable documentation of this working but would be super happy if it did~

300 f/2.8L and 400 f/2.8 at f/2.8

I have a technical question to ask the forum. I already have some ideas on what is going on, but I don't really know for sure and wanted to ask, since many of you are so knowledgeable. In advance, thanks.

I tested my 300 f/2.8L I IS vs. my 400 f/2.8L I IS yesterday at a track meet. I felt that I had more OOF shots with my 400 and wanted to see if that was really true or not. So I set up at the end of the back straightaway, and shot runners running towards me (from curve up to about 20-30 yards away from me). I set the lenses both to f/2.8.

I shot with the 300 and the hit rate was unbelieveable. The faces were razor sharp almost everytime. My settings were 1/5000, f/2.8, auto ISO. I was in Servo mode on a 1DX.

I then shot the same settings and the hit rate was much less with the 400. A lot of the focus was missed (can see another area in focus just slightly to the right or left on another runner) or the faces were just soft and there was no real apparent focal point anywhere in the photo. However, it did hit a lot of photos, and again, those were incredibly sharp.

I did realize of course that with the 300 the runners are closer to me when I fire the shutter, vs. the 400, which could matter.

Is DOF (f/2.8 is pretty thin) more difficult to manage at longer focal lengths? Remember up until this year I had only used a 300 for sports and didn't buy the 400 until last July. Is IS more of an issue, even at 1/5000? Does the lens focus slower or not as accurately as the 300? I was thinking it's not AFMA since when I shoot golf with it I never have any OOF shots, ever. Of course they are not moving much in golf, so I'm afraid the track problem could be my bad technique with the 400.

Just thought I'd ask since of course as you can imagine, it's sort of frustrating. Thanks a lot!

Stolen lens database?

Hey all, Is there a place where i can check if a lens is stolen (given that i can get my hands on the serial number).

There is a 400 f2.8 IS II up for sale, a little ''too cheap'' imo.

New it costs 10800 here and its being sold for 6000 (without receipt or hard case), looking to be in good condition when looking at the photos.

I tried to google about a stolen 400 f2.8 IS II but nothing shows up.

It's a bit fishy.


Thanks

A 4000$ budget for Lenses on 5D3... need suggestions

Hello CR folks,

I recently bought a 5D3 and 50mm 1.8.This is my first investment and I am based out of India.
I mostly shoot Low Light , Landscape , Street Photography and Slow Shutter captures.

Before taking up 5D3 I had an experience of working with my colleague's Canon60D , 18-135(kits lens) ,70-200mm f4 and NikonD7000 50mm f1.4,70-200mm f4.
I had some severe limitations while shooting Landscapes and didn't get enough experience on wide-angle shots :-[
I will be travelling to Ladakh,a landscape,rich cultured,wildlife Himalayan Range in the month of July and I am looking for suggestions to get some 'real' gear.
All I can say that this will be my starting point to get into some real action ;)

I can spend up to 4000$ on the Lenses.
Please share the gear details based on your own experience.

Regards
Hari

---------------------------------------------------------------

Update :
Thanks for the suggestions Guys
I decided on getting 24-70 2.8 and 70-200 2.8

5D MK II Error - Pink Frame

Ladies and Gentlemen!

I have a 5d MK II, bought from ye Canon refurb store, and the other day, it randomly started making frames like the one attached. When I would take the picture, it would simply capture whatever the previous image was, but with a pink cast over it. Removing the battery would help, but, then it randomly stopped doing the error. A week later, it started doing it again, for no clear reason.

Then, tonight, it started doing it again, for no clear reason! Here is an example frame. It seemed to be doing it a lot more tonight than the previous time...

6D. Lines in shadows

Hi,

Some time ago i notices vertical lines in dark areas in my video. Then i took few more samples and now i'm sure, there is a constant problem with these lines.

Take a look at this vid:
https://dl.dropboxusercontent.com/u/5020311/MVI_3580.MOV
or this screenshot:
https://dl.dropboxusercontent.com/u/5020311/6d%20lines.png

or this vid:
https://dl.dropboxusercontent.com/u/5020311/MVI_4113.MOV

look at dark area...

Guys, owners of Canon 6D, can you check your cam? lock iso on 100 and take a sample in dim light, will you have these lines?

Jammed Filter

Hi all
I unfortunately dropped a lense or of my bag today onto the floor.
Unfortunately it was a bad choice.
It was a 70-200mm is II so it was a Big Bang. The lens looks intact but the UV filter is jammed and dented.
I've tried using a washing up glove to get grip and putting it in a freezer.
It didn't budge a millimetre .
Anyone got a suggest as to what to try next
Kind Regards

5D mark III problem - 32gb sandisk extreme pro destroyed

I encounter a problem with my 5D mark III that destroyed one of my cards.

The problem appeared when I locked two pictures on the card and after that I erased all pictures fron the card except the locked ones. The erasing proces started and after few seconds (10-15 sec) appeared the message "the card is not recognisable". Tried different approaches: close and open camera, remove and put back the card, try to format the card on 5D mk II, try to format on MAC, PC, tray to accese it with IPAd, but the card remained not recognisable by any of the cameras, pc`s, mac`s or Ipad.

Is just broke.

Does anyone knew something about this issue?

Thanks,

Robert

How do you prevent buttons from being accidently changed on Canon 1DX?

As a photojournalist, I tend to have 2 and sometimes 3 cameras hanging on my body (usually one wide-mid range zoom and a 70-200 on the other body) and since I am shooting and on the move constantly at most events I have had plenty of problems grabbing my 70-200 (with my 1DX) and finding that all the settings have gotten changed as it bumps against my body (I do tend to turn the top of the body towards my boy versus hanging outward as I have found that it gets beaten up more when it's facing out (i.e. the hotshoe and top facing out, versus turned inward to my body)...

So long story short, I'm getting sick of this as I have milliseconds to respond, grabbing my camera and then I get it up to my face and find I'm on ASA 10,000 and shutter speed of 1/8000....it's starting to get really annoying...

So I figured out how to set-up the multi-function lock so it will lock back dial and multifunction dials and I figured out how to disable the modes down to just manual (I NEVER shoot on anything other than manual or bulb) but the thing I can't figure out is there a way to disable the small ISO button on the top of the camera near the shutter speed dial?...between shutter speed dial (which I can lock via multi-function lock) I can't figure out if there is a way to lock/disable the ISO button? the ISO and the Shutter speed dial seem to be the things that get changed the most often...I can't seem to find anything about disabling the ISO button or locking...anyone have any ideas?

Thanks....and just to answer in advance, no I don't want to use some wierd new harness contraption that someone has come up with...maybe good and fine for shooting weddings but when you are covering protests, riots, war zones, NFL games, etc...I have not found one that would be more dangerous than useful...

near future lens size and resolution

My interest is primarily with wildlife photography and in this thread I want to explore the near future (the next decade - if you can consider that near) of telephoto lens inovation. Over the past 2 or 3 decades telephoto lens size appears to have changed little - is this going to change over the next 10 to 20 years?

1. What specifically restricts lens size with existing DSLR technology? Does the distance from the sensor to the lens make enough of a difference that future telephoto lenses on mirrorless systems will be substantially smaller? (forgive me for assuming that mirrorless cameras will replace DSLR)

2. Ten years from now, when you're shooting with a 100mp mirrorless camera body, will it still be an advantage to shoot with a massive 600mm f4 lens, or will cropping to a 20mp image with a significantly smaller lens eliminate the need for a super-telephoto? There are certainly differences that will be difficult to overcome, such as tracking wildlife from a distance and accurately focusing at that distance with a smaller mm lens. Do you think these challenges will be met?

In a nutshell, 10 years from now (when I finally have 10k to spend on a lens) will I still want to purchase a 600mm 5kg lens for optimal image quality?

5D3 Pricing

Well, I was about to go ahead and pull the trigger on a 5D3 about 3 weeks ago ($2949) at B and H, but of course I procrastinated. In the last week or so it was back up to $3199 (more, but OK). Then today, it's $2999!!! I think instead of stocks, I will just invest in a whole bunch of 5D3's.....

Seriously though, anybody have any thoughts on when we can expect at least a little price drop? Right now D800's are $2796 at B and H, which seems like a pretty significant differential for 2 pretty good directly competing bodies...

I need mine by June, so hopefully a little reality sets in soon...

What made you choose Canon in the first place?

I picked up a Nikon 5100 and I actually kind of liked it. But then I thought to myself, why pay the same money for a Nikon that was not even made in Japan? So I went for Canon and got a 60D. Stupid reason I know. 3/4 of my friends shoot Nikon. I don't like to be asked to lend lenses. That's another reason. ;)

Sometimes I wonder if it was the right decision. I have a 6D now. Nikon D600 seems pretty attractive. I'm not going to switch over to Nikon. The switching cost would be too high. But are there things about Canon camera, lenses, or optical technology that are superior to Nikon? I'm not really looking for validation, but I'm curious to learn more about Canon since I consider myself a newbie. Please share your views.

Nikon D800 Value Dropping?

There is a almost new D800 on our local craigslist (not a scam) for $2100. I checked ebay and noted that there were a lot of sales in the $2200 range, some even included a cheap lens.

Why are people dumping them? I was tempted to get it as a 2nd body to my 5D MK III. I have several Nikon lenses. Finally, I decided that I'd pass it up, if others don't want them, I won't be able to resell it a year from now without losing money.
I did buy one new last May for $3K, and later sold it for $3200 when they were hot items. There are some better lenses now available or on the horizon, so the lens situation is not so bleak as it was.

I think I'll wait for a new backup body and see what the year brings. I just bought my 6th 40D this week, its great for my product photography, but isn't capable of ISO 6400 or 12800.

Please share your camera settings

Ken Rockwell claims that he doesn't need to shoot RAW and he said if you know what you are doing JPEG is fine. He also said the smallest size JPEG is good enough.

well I think I know what I'm doing but I need RAW. Anyway, my real question is
1. what size of RAW and JPEG do you normally use?
2. do you use camera NR at all? or do you use LR?
3. what settings would you advise against and for?

Canon 1.4X III vs Canon 2.0X III

I am looking at both the Canon 1.4X III and Canon 2.0X III. What I am confused is why they are both at the same price. Been reading some reviews on the web, but given that both are the same price, which one to choose? I am aware of the loss of 1 or 2 stops of light as well as image quality being not as sharp. I have a 7D and 5D3 with 70-200 2.8 II. I would love the notion of extending the reach to 640mm on my 7D, but I don't know if that means that my image quality would suffer greatly or settle for the 1.4X and be limited to 448mm. Or I can settle for 280mm or 400mm on my 5D3. My intent for the extra reach would be for wild life.

Any advise? Thanks in advance.

Keep my 70-200 f/4 IS?

I just bought a new 70-200 f/2.8 IS II and still have my 70-200 f/4 IS. I'm guessing others have probably "upgraded" as well and I'm wondering how many of you kept your f/4 or if you sold, any regret you had. I have the 85 f/1.2 II and 135 f/2 plus teleconverters so I could use those for travel or when I need lighter weight.

I'm just wondering if I'll ever use the f/4 again, but it's been one of my favorite lenses, so I'm not sure what to do.
