Has anybody used an Aputure Gigtube wireless with a 5D MK III ?
If so, what model of Gigtube did you use
Thanks

Thank you for all the feedback. I'm ok with a little noise; I got the photo attached tonight and it has been put through LR4 for lens profile and 30 NR. That one isn't too bad but the wiggle room for either less noise or more shutter/aperture would help.

I have no experience with the 5DIII. Among other things, I shoot live theater. I've been shooting pro bodies for a decade...typically keeping the previous body as backup to the new body. I'm currently using a 1DX with a 1DIV as backup. I've also held onto my 1DsIII because I shoot actor headshots and I wasn't sure if the IQ of the 1DX would be up to to the task (it is).
I've decided that I will purchase a 5DIII as a backup. It will be a little weird for me to shoot a normal sized camera again. It seems the AF and high ISO are similar to the 1DX and I would like a smaller body for travel.
Since acquiring the 1DX, I've settled into using 5000 ISO for live theater. I'm hoping the 5DIII will give me similar results. Here are a couple at 5000.

Nice images Brett.

Its fun to shoot live theatre, I particularly like it when they turn out the lights and have just enough light so a person can see the action. That's where the 25600 ability comes in. Of course, most of the time, ISO 3200 or even less is fine, but when the lights go down, that's where the challenge is.

I'd get a 1D X, but haven't been able to justify the difference in price to myself. I had a 1D MK IV and used it to 12800 quite nicely, but went back to the smaller body to to carpal tunnel issues in both my hands.

The 5D MK III degrades gracefully at extreme ISO settings, so even though their is noise, it doesn't increase on a steep curve as the ISO goes up.

Faster, stronger, and enough DR to make you hang out in Nikon forums mentioning DR every time someone posts about anything.

Or to put it another way, no-one knows. Its all speculation at this point. But I'm hoping for the DR bit, if for no reason other than a bit less shadow noise in this forum.

Before buying the M + 22mm (and being very impressed by how accurate its focus is when you use the zoom thingy on the monitor for small objects) I thought I would never want a camera without a viewfinder and a fixed focal length (I realize it's not fixed on the M, but for me it is for now), especially one that's relatively wide. But as long as they're fairly inexpensive relative to the price of a lens by itself, it occurs to me - as it has to others - that they're a good alternative to carrying around another lens: if I have to carry another lens around, I might as well carry another camera if it's small enough and save myself the trouble of changing lenses. (If this M + 22 deal had been available when I bought the Olympus 17mm f/1.8 for my OM-D, I would have bought the M + 22 instead and saved myself $200!)

Two or three would probably suit me in addition to the M + 22 - 50mm equiv. & 70mm equiv, and maybe 24mm equiv for occasional use (more if a small longer lens were feasible). If just one, I guess 50mm equiv.

Canon has been running nearly continuous rebates for two years. I bought a refurb 70-200mm 2.8 MK II when they had their 15% off sale which put it at just under $1700. Its perfect, and I've been pleased with it.

You have to be very quick to find it in stock and at 15% off. I waited 6 months before I snagged one.

You can sign up with canon price watch and if you carry a smart phone with you, it should not be too hard to grab a refurb when they are available. Unfortunately there are not refurbs of the great white (300 F2.8 and up).

Does any one else think it is *interest* that one of the pixel dimensions is 8192, a power of 2. I have never seen that in any camera before. : Looks like someone made up a rumor without even thinking about it carefully.

Health to use your 400D, I loved mine.

It's a great little camera. I got mine after I already had my 5D2 and 7D, just to use when I needed something light and portable. It really holds its own, even though it's a relatively old body by now. I replaced it a few months back with a Sony NEX-6 and finally put the 400D (and the 55-250) up for sale last week. They're both in the hands of happy new owners now.

Adorama canceled my order for the $299 EOS M and 22mm lens (which was placed in early July and apparently couldn't be fulfilled).

I feel very lucky I ordered from B&H and not Adorama when EOS-M/22mm was already backordered. It looks like B&H decided to bite the bullet and honor the backorders with EOS-M/22mm/90EX kit (currently on sale for $399 at B&H) instead of cancelling them.

http://www.canonrumors.com/forum/index.php?topic=16074.0

I think that most users on the forum would not even consider using the camera to crop a photo. DPP comes with your camera, its a better tool for cropping. Many use Adobe Lightroom which will easily crop your image to a desired format such as 4 X6, or 5 X 7, for example. You can set custom sizes as well.

Some cameras allow you to set a different format size before you capture the image, and then the image is cropped to that size when opened in DPP (Canon editing software)

I also believe you can crop in the print menu, and the image will be cropped when you print directly from the camera. Not very useful unless you must print directly from the camera as part of your work flow.

I can't find anything from ChipWorks that doesn't cost a hefty penny. I did find this article that determined the DIGIC 4 was a 65nm part:

http://techon.nikkeibp.co.jp/english/NEWS_EN/20090218/165866/

Additionally, the DIGIC 3, a very old part at this point, was manufactured on a 130nm process:

http://techon.nikkeibp.co.jp/english/NEWS_EN/20090218/165867/

Canon has been using far smaller and more efficient manufacturing processes for their DIGIC chips for quite some time. The 500nm process is just an oddball thing that has apparently permanently attached itself to Canon's in-house CIS products. Aside from some assumptions about it being less costly and still effective (from a "consumers are still quite happy to buy their products" standpoint), I don't think anyone really knows why they are still using such an inefficient manufacturing process.

I would be willing to bet DIGIC 5 and 6 are manufactured on at least a 32nm process. I am not sure if they have moved to 22nm...that is fairly cutting edge at the moment, and extremely costly, so I am a bit doubtful. I don't suspect we'll see anything at 22nm or 14nm in any Canon CMOS device for quite some time.

So, looks like someone else is experimenting with an alternative color filter array. Specifically, RC,CB 2x2 array. C being clear, so having no filter over it instead of a green filter, while still having R and B with standard filters.

Ever pinch your finger in a Manfrotto flip lock? Extra points if you've done it in -25°c temperatures!!1!

One of my older Manfrotto tripods not only had the vicious flip locks, but the edges of the fliplock had this very sharp plastic flashing. Crikey, they could not have made it more dangerious unless they put metal teeth on it.

Not keeping your finger out of the way is a mistake you make ONCE with some of the older Manfrottos. Yikes that hurt!

My newer one still has the flip locks but the edges are at least more rounded.

I disagree that you disagree.

Seriously, I think we are saying the same thing. 5DIII targeted to a professional market to fit a specific need. D800 targeted to...whom? I've never been sure.

The 5DIII may be $500 more camera, but that's because it has features that make it worth that to a specific market.

Click to expand...

Agreed

I think the 7Dii will follow the same path. Many sports 'pros' use the 7D as a much more affordable 1D -whatever. My guess is the next one will be basically an APS-c 1Dx.

My copy of 24-70 f/2.8 II needs -9 at wide end and 0 at tele end on my 5D III. My Canon 70-200 f/2.8 II needs 0 at either end, and my 100L also needs 0. Some of my fast primes including 35L, 50L, 85L II range between -1 and -3.

A brand new Canon 17-40 f/4L I just borrowed needed -6 at wide and 0 at tele.

-9 seems a tad too much for a $2100 lens, so I'm just wondering what 24-70 f/2.8 II owners have experienced with AFMA (and 5D III)? Is it worth sending in the lens to Canon while still under warranty for calibration?

Is my copy of 5D III partly at fault here, as the body seems to need Minus AFMA on lenses, never positive. The body is out of warranty, but should I send in both the 24-70 II and body to Canon for calibration together (does Canon even calibrate a specific lens+body combo?).

Any help would be appreciated.

Click to expand...

As long as you can get it setup what does it matter. Some people seem to get so worked up about the number and dream up reasons to be unhappy.

Click to expand...

A lot of the concern is due to future resale value, ease of sale given full disclosure, etc.

Click to expand...

So you,re worried that someone else will be worried that a lens camera combo will be outside limits. Not much chance of that coming true due to manufacturing tolerances. I for one am very glad AFMA is on my camera.

Yes it is UniWB. It basically give the camera WB adjust coefficients of 1.0, 1.0, 1.0, which means WB is NOT applied at all.

Then you use flattest tonal curve by choosing Neutral picture style, then dial down the contrast to lowest, sharpness to lowest (to remove sharpening halo)

Then the histogram will be a lot better resembling what the RAW records.

Of course the output JPG will be garbage, all green and stuff. But if you enable highlight blink, you gets RAW blinks too!

There will still be a bit of discrepancies between UniWB histogram/blinkies and the real RAW data but at least it's a lot closer.

Oh, while you are at it, don't forget to shoot a white card in the scene to restore WB in post.

Anyway, I found a website that had publish some UV filters test result with transmission and absorption curve:
https://ww2.chemistry.gatech.edu/~nmakarov3/INTERESTS/Photo_Filters/index.htm

Interesting to see the EF 50mm 1.4 lens also block UV light...

Click to expand...

IIRC, Lenstip also tested transmission of many UV filters with a spectrophotometer.

It's interesting that the 50/1.4 blocks some UV, but not surprising. Standard microscope objective lenses don't transmit UV all that well, so for applications with UV fluorophores, we use objectives specifically designed for better transmission down to ~340 nm.

Something is up with the CPS points. 30D is still 1point, but 40D, 50D, EOS 1D Mark II N, EOS-1D MARK II, EOS-1D and other are listed as 0 points. Here's the kicker the EF 200-400mm f/4L USM Extender 1.4x is also listed as 0 !

For some reason the 200-400 dropped from 12 pts to 0 pts. Not sure why - I asked CPS about this but did not get a satisfactory reply

Nope nothing showed up but I called up my local canon dealer after I got the mail and he said the 600ex-rt was free with the 24-70 kit and it was valid till last month.

Now I called up Canon edge global customer care support and they told me that the offer is still live and its available with both 24- 105 and 24-70 kit with a limited stock and its been kept covert for canon edge members only.

I got confused after hearing that so I wrote a letter to Canon asia and I am expecting a call from their office soon. Will let you guys know as I receive the confirmation from their office.

This is really starting to get ridiculous, who needs a 1200 mm equivalent in a body that's impossible to hold still??

Superzoom compacts have moved away from usefulness to marketing gimmick IMHO.

Click to expand...

Got one here to complement 5D3 and 60D. As Mt Spokane says, not very ergonomic but light, inconspicuous, pure fun. I use it 95% of the time at 1200mm handheld.

Click to expand...

My girlfriend has a Panasonic Lumix FZ-50 which has a 12x zoom and 35 - 420 mm equivalent and is f/2.8 - f/3.7. It takes fabulous pictures given enough light, but so far the 420mm equivalent has been enough reach. What's lacking in this case is more wide angle, something that she's missing a lot. So we're actually looking at something new.

The FZ-200 looks great, 'only' 24x optical zoom (25-600mm equivalent) but it is full range F2.8!!! What's missing is the manual controls of the lens that the FZ-50 has. That really was/is a special superzoom camera.

Click to expand...

I have an FZ-50 too and I love it- if it wasn't so noisy I'd probably still be using it more regularly. It's got better ergonomics than entry level DSLR's. Although the LCD seems so TINY now.

I know there's probably physics involved blah-dee-blah but I really can't fathom why there isn't even a 1/1.7" birdge/superzoom (or even better, something like Nikon 1 series). Once you get past the miniaturization constraint of most point and shoots, it seems like there would be a way to get something reasonably sized.

To me there seems to be something wrong with the "S" lens results. When comparing it to the "EX OS" version it is as good wide open and bare.. but with extenders its way worse in the centre and better in the corners. Something fishey with that. Here is the comparison @600.
http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=803&Camera=453&Sample=0&FLI=7&API=2&LensComp=844&CameraComp=453&SampleComp=0&FLIComp=7&APIComp=1

I would expect the "S" to give better IQ with a Canon 2x III than the APO Sigma 2x.

There seems to be rave reviews every where about this lens. Another thing to remember is this lens costs much less than a Canon 300 2.8 II or 200-400 so I would never expect to get equal results. But for 3K, if I could get 85% performance of Canon supertele in a similar focal length than that suits me just fine.
Personally if I was thinking of a 300 2.8 to use primarily with extenders I would go with a SH Canon 300 2.8 IS or wait to see if a Sigma 300 2.8 OS comes along in a couple of years which should give better quality with extenders. Thats what I will be doing for now anyway since I dont have the funds right now to upgrade my Sigma 300 2.8.

By the way I think the 120-300 S should be dubbed the "Sexma"

Wow are there really people complaining about the 135L and linking comparisons with the 200 f/2!?!?!? $6k vs $900, I'd hope to god the 200 f/2 was better for costing 5x more.

I thought the fact that the 135L is one of Canon's sharpest lenses and best values was just common knowledge, never ever seen anyone complain about it. And test charts can only tell you so much, try real world use and then come back and complain. I mean for you to say that I can only believe you've never actually used one.

Click to expand...

+1, but again it's possible there is some sample variation...even with a Canon L lens.

Click to expand...

Hmmm could be. I've not noticed all that much purple fringing, perhaps wide open in a brightly backlit situation you can and even then in the corners. Nothing like my 85 1.8 did! That thing drove me nuts!

I absolutely love love love my 135L. I mostly use it between f/2.2-2.8 which gives amazing results. I do wish it had IS but it's not a big deal. You can get sharp shots at around 1/125s. Does take away some of the low light advantage. Then again people don't stay very still and IS can't really help with that!

I recently used it on my 7D and the IQ was just outstanding. So good in fact I mislabeled my images as from "5D2" on import!

Click to expand...

+1

Quick update, for what it's worth:

Gave the 24 a reasonably wide range of subjects and finished a shoot on a 1Ds Mark II body, and the accuracy and performance were remarkably improved, even in pretty significant low light situations. I'm thinking this lens is just too sensitive for a lesser camera body's AF system. The 1Ds II's AF is even a little dated compared to, say, the 1DX, or what have you, but regardless, there was a CLEAR difference in performance. I haven't sat down and played with the DVD cases like I did before, to test the exactness of the accuracy, but I'll do that soon...

Haven't gotten a chance to give it a whirl on the 5DIII yet, but when I do, I'll let everyone know.

I had a mark 1 that lost infinity focus and couldn't be repaired unless I could source a donor lens with a different fault.
By that point I threw the towel in, optically there is no difference in any case.

I wouldn't buy a mark one now, mainly because of the parts issue, 23 years is a lot of iris movements etc...

They have become a cult item, fair enough, i just kind of think if you are going to spend 50% more for build quality then why not go that little bit further and get improved build, improved focus, improved bokeh, improved max aperture and pick up an in warranty in production servicable 1.4 instead?

I settled for the plastic fantastic.

Click to expand...

Actually from what I've heard the 1.4 is not really that reliable, with stuck focus rings for instance. History shows the Mk I to be remarkably durable, so it's worth having a unit that hasn't seen that much use over the years (hooray to my sublime copy )

Nothing wrong with the plastic fantastic by the way, given its low pricing (but still I prefer the Mk I).

South Western CT is bundled under the "NY City" area and it's crazy how much they want to buy for and how much they want to sell for. Either that, or the stuff doesn't stay up longer then a few hours . . . I'm not sure which.

Good for you, either way.

I got my refurbed 7D yesterday (looks new) from Adorama all for $889 w/1 year warranty (through Adorama). I was waiting to see what the MK2 would yield, but at this price point, I couldn't resist. The AF on this thing is totally crazy. It's like the starship enterprise, no wonder people have been excited about it.

Since I got into my 60D @ $850 new in October 2010 and they're going around $500 now, I really can't complain.

try setting it to P mode and see if it works there. If it doesn't then you probably have a problem with your camera but if that works fine it's probably down to your settings. The small built in flash will generally prefer as wide open aperture as possible and a shutter speed of less than 1/200. Crank up the ISO a little to get more oompfh out of it.
