I bought a slide duplicator that mounts on my camera, using a t-mount. The item I bought was similar to this, but not exactly the same:

http://www.ebay.com/itm/Zoom-Slide-Duplicator-T-Mount-MINT-/121050627342?pt=Camera_Lenses&hash=item1c2f2dfd0e

Here are some pros and cons...
  • Pros
    • Fast - Make a copy as fast as you can insert the slide/negative and take a picture. My scanner takes a minute plus to scan a hi-res image.
    • Hi-Res - My DSLR makes a much higher resolution copy than my scanner
    • Better Color - My DSLR gives better color than my scanner (for slides). I haven't been able to perfect the color profile for negatives, but I am working on it.
  • Cons
    • Have to load one at a time. I can load twelve slides/negatives at a time in my scanner
    • I don't have a good color profile for negatives. I get good results, but not great, due to the fact that I have been unable to dial in a good profile for correcting the negatives. The scanner has a built in profile for handling the orange background on negatives.
    • Works well with mounted slides, but my negatives are in strips. I had to modify a film strip holder so that I could properly hold my negatives in place.


I have a bunch of old 35mm negs that I need scanned. About 20 rolls of 36 exp, cut negs.

I priced it out and it'd be about 500-700 to get it scanned locally.

Since I have the time and good equipment I thought I might try this myself?

If I did it the cheap way, I'd use my 5dII, 35mm f/2, 25mm extension tube - that would give me almost 1:1 magnification. Negs on a lightbox, make sure my planes are all parallel, kill all ambient light, shoot at about f/8 with mirror lockup, either live view or shoot tethered to fine tune focus.

Or, a speedlite instead of the lightbox? Would that yield significantly better results? Or if I wanted to sink more money into the project, I could buy a 100mm macro instead of the same money going to a scanning place.  ;D

I know it's a bit off topic, but I also used one of the inexpensive rain bags for shooting a "Color Festival". That damned chalk/corn starch, get's into everything.

I will admit however that I left my better equipment at home. I shot with one of my backup cameras and a decent, but older lens that I felt I could risk.

I put a UV filter on the front of the lens, installed the bag around the eye piece. I taped the bag to my lens hood and sealed the other end. I also made sure I went in with a fully charged battery, because I didn't want to risk a change.

If you have ever been to one of the color festivals, you would know that a guy with a camera quickly becomes a target.

Other than a bit of chalk on the filter and exposed parts of the hood, everything came out clean.

Like a camera, the best rain bag is the one that you have with you when you need it.

I always keep a couple of these in my bag. They are inexpensive and don't take up hardly any space. Sure, they are not the best, and are essentially disposable,  but they work well in a pinch. They come two to a pack.

I have a couple of nice rain bags, but they rarely get used. I don't normally carry them with me, due to the bulk, unless I am expecting trouble.

I plan to pick up a 1.4x III. I expect it will be as good or better that than the 1.4x II. If not, I'll return or sell it:)

Thanks everyone for you input.

I sold my 5D II over a year ago, so I can't remember all of the specifics, but as far as the beep and lighting up, is the camera by chance in "AI Servo" or "AI Focus" mode?

There is a switch in the battery compartment that shuts the camera off, when you open the battery door. I know it's a long shot, but see if you can find that switch and activate and/or deactivate it with something. It might be jammed.

My wife dropped her PowerShot and had a similar issue. It would no longer power on, so she bought a new one. A few months later, when I had some time to play around, I got a tooth pick and used it to probe the battery door switch. It had somehow gotten jammed. The toothpick freed the switch and the camera sprung to life. It is still working today.

Like I say, it's a long shot, but it's worth a try. I could certainly see something similar happening based on the description of your issue.

Lenses / Re: Canon EF 1.4x II vs EF 1.4x III

I plan to use the teleconverter on a 400mm f2.8L IS II and 1DX, 5DIII, etc.

I shoot a lot of sports, so fast and accurate focus is important. You don't often get a second chance. The speed and accuracy is supposed to favor the 1.4x III. I've seen the claims that it's faster, but no numbers to back them up and the 1.4x II works quite well.

For this particular application I am not too concerned about the corners. Sharper corners is better, but not a priority.

To my eyes, looking at the center and mid-frame, this comparison on tdp favors the 1.4x II, but they are close. Unfortunately, they don't have a comparison, using the 400mm. I guess it could be my eyes, or maybe tdp the setup needed a bit of AFMA. That's why I am hoping to find more examples.

$200 is not a lot of money in a relative sense and I'll probably bite on the 1.4x III, but am just trying to make an informed decision, before I commit.

Lenses / Canon EF 1.4x II vs EF 1.4x III
« on: July 12, 2014, 09:09:04 PM »
Can anyone here provide photographic comparisons between the Canon EF 1.4x II and EF 1.4x III that actually show the EF 1.4x III is really as sharp or possibly better that the EF 1.4x II?

I see all sorts of claims that say the 1.4x III is slightly sharper and has higher contrast, but I have yet to see a photographic comparison that actually proves that.

I looked at the comparisons between these two teleconverters on the digital picture for both the 200mm f2 and the 70-200 f2.8 IS II at 200mm. In both cases I believe the 1.4x II is actually sharper and higher contrast, regardless of the conclusions they drew.

I already have a 1.4x II but am considering a second 1.4x teleconverter, since I frequently carry two or three bodies. I was leaning to the 1.4x III, but I have yet to see any comparison or claims from Canon that would convince me to spend the extra money.

EOS Bodies / Re: Eos7D mk2, How EXCITED will you be if . . .?

The 7D Mark II will have to be something really special for me to get excited about it. Had it come out a year ago, with some of the rumored features, I would most certainly have one by now. I may be a bit envious of some of the new features VS. my 7D Mark I, but not enough to splash the cash. At least, not any time soon.

I have since shifted up stream with a 1DX, 5D3 and still have my 7D Mark I and have added some better glass. There are many good light situations where the additional reach comes in handy and I pull out the 7D Mark I, however as soon as the light starts to go, the 7D goes in the bag.

I expect the 7D Mark II will have several desirable improvements, but I don't believe it will even begin to come close to the full frame bodies, in low light, which has been my biggest nemesis.

Of course if I was made of money, I would have them all:)

Software & Accessories / Re: DPP 4 not recognizing my lens
« on: July 06, 2014, 11:29:55 PM »
Is this file a jpg or a CR2?

I ask, because after seeing your issue, I went through several folders and looked the info to see if DPP4 was recognizing my lenses. In each case the info screen showed the proper lenses and I have download profiles for them. Here are some that I checked: EF 24-105, EF 135mm, EF 70-300, etc. It says "Lens data: Not available" for all of them, when looking at a jpg, but when I look at a CR2, the lens is properly recognized and data is available.

This sounds like it may be a bug or at least a temporary inconvenience, until Canon adds additional support and functionality to DPP4.

The default on mine was to use shooting color space as the work color space.  That keeps a user from ending up with a impossible combination.
Great suggestion! I usually shoot AdobeRGB, but not always, so that makes a lot of sense. I just changed to "Use shooting color space as work color space" and it looks good. Thanks!

At least now, I'll have an idea of what is happening, should I run into issues again.

Is there a US/North American version?  Don't see it.

FYI: I am using the US version of DPP4. I downloaded it from Canon USA's site on 6/21/2014. I believe it's only available for download, under supported cameras (1DX, 5D III and 6D) and you do have to enter a serial number, before it will let you download the file.

I think I may have figured it out.

When I installed DPP4, I didn't set any color spaces. I expected, like most software it would properly detect my settings.

After discovering the display issue, I went in to preferences in DPP4 and tried every combination of the color space/display settings. The only ones that displayed correctly were the sRGB settings.

This was odd to me, since the image was shot on a 1DX as a jpg, using the AdobeRGB color space and I am using a wide gamut monitor, which I believed was also configured with an AdobeRGB profile. I don't know how to check the color space on a profile, so I recalibrated my primary monitor and generated a new profile and ensured I chose AdobeRGB.

After generating the new profile, the sRGB settings still worked in DPP4, but just for kicks I switched the DPP4 preferences to AdobeRGB and they now display correctly, as well. I'm guessing that I must have accidentally generated an sRGB profile previously or that it somehow got corrupted.

Has anyone else here run into this issue with DPP 4 (See attached image)? This doesn't happen with DPP 3 or any other software that I have used.

I have two monitors. In DPP 4, the colors are messed up on my primary monitor, but when I drag to the secondary monitor they look good. Both monitors are color corrected using an iProfiler1.

The left image is on my primary monitor and the right image is how it appears, when I drag the same window to my secondary monitory.

EOS Bodies / Re: The Always Hidden Camera at the World Cup
« on: July 04, 2014, 02:28:13 PM »
I don't like to shoot with rain covers unless I absolutely have to. They are bulky and get in my way. Which makes me wonder, why so many camera's at the World Cup are covered. I have seen several, not just the one in the photo. I could understand, if it was raining, but from what I can tell it hasn't rained or even sprinkled at any game that I have watched.

I agree that there are probably better ways to conceal a prototype, so why else would someone put up with the inconvenience of a cover, in conditions that don't seem to warrant one?
