EOS Bodies / Re: Patent: Canon EF 180mm f/3.5 DO Macro
« on: Today at 11:13:27 AM »
I've been hoping for a 180 II, but was hoping for f/2.8, 9 bladed diaphragm, and the like, not DO.  Let's hope this is just a defensive patent.

Ditto.  And IS.

I have a question: in the link posted http://petapixel.com/2012/12/24/how-to-scan-your-film-using-a-digital-camera-and-macro-lens/
the author says 4-6 shots are required for a 35mm image, but he is using a Zeiss Makro Planar, and a 1:3 magnification.
What I don't understand is, unless the magnification is greater than 1:1, why would I need to take multiple images and stitch. Can someone clarify?
Thanks!


The author is stitching multiple photos in order to extract the most detail from each negative/slide.  The explanation:

"Using an higher reproduction ratio is more time consuming (you’ll need more shots to cover the same area), but as a result you will be able to extract the most detail from the film. Here are some examples showing my Canon setup at various reproduction ratios, compared to the results of a well-respected flatbed scanner, the Epson v700..."

The exact numbers depend on the size of the negative/slide compared to the size of the digital sensor.  Using 1:1 for a 35mm negative would require stitching multiple shots on an APS-C sensor camera, or just a single shot on a full-frame digital camera.

There are flatbed scanners capable of scanning film negatives that are affordable and supposedly quite good.  I plan on getting the Canon CanoScan 9000F MKII scanner, and it is listed on Amazon around $180 US.  I just need to clear up the funds and the desk space first.  For 20 rolls of 36, I think it would be much easier and the quality much better. 

If you already have a good flatbed scanner but it doesn't do film negatives, I read a DIY article that showed how to make a box to reflect the light from the scanner around behind the negative.  You could also try that on the cheap.  I'm pretty sure it was this article:  http://makezine.com/2011/07/13/how-to-cut-and-fold-slide-negative-scanner/.

Lenses / Re: What Lenses are missing from Canon's range

Canon could add a non-tank like 28-300 similar in price and quality to the Nikon 28-300 as well as the Nikon 18-300.  I use the 18-300 on my D7100 and that has replaced by for my event camera which was a 60D with 18-200.  I've been surprised just how good the 18-300 and D7100 combo is.  They have been a joy to use.

Agreed.  I'd like to see the 28-300L remade along the lines of the 70-300L - compact, twist zoom, light, great IS.  It would be great to have a full-frame all-in-one with L quality that didn't break your neck for hiking, kids sports, etc. Although if they're gonna list it at $3k, don't bother.

+1, and maybe an L-quality 28-200 f/2.8-4.5. From what i understand, the 28-300's are popular with paparazzi taking red carpet shots at premieres and award ceremonies. My guess is that 200mm would suffice on the long end.

I would accept 200 on the long end but you can always hope for more!  If they did a 28-300L remake, though, it would be harder to justify alongside the 70-300L unless there was a significant variant in terms of cost or focal length.  I'd even be happy with a quality non-L 28-200 or 28-300 with current technology.

Canon General / Re: New Speedlite Coming? [CR2]
« on: July 16, 2014, 12:59:12 PM »
I can't wait.  I hope this is the 4?0EX-RT everyone is expecting.  I'd love to get three flashes and a controller for under $1k.  I know the 600 is well-loved, but I can't justify it unless I could catch a refurb under $400.  Even if I did, I wouldn't have anything to use the radio functionality with anyway.

EOS-M / Re: Looking for a wifi Sd card or an eye-fi?
« on: June 24, 2014, 05:26:56 PM »
I got the Toshiba Flash-air when it was a $20 deal at Adorama.  You cannot turn off the wi-fi on the card to save battery life.  Also, once you set up the connection to the phone/tablet, if the camera powers down and then powers back up, the wifi connection to the camera is lost (on my iphone 4s at least) and you have to reconnect.  Toshiba does have an app that you install on the iphone/ipad, not sure about android.  The app is pretty simple, and I got it all set up and working in short order. 

I haven't used it as much as I would if the feature was installed in the camera.  My intent was to use it to add the Wi-Fi functionality to my G1X Mark I until I can afford the Mark II, just like on my 6D. If you get a good deal and do not expect to replace your camera with one that has wi-fi inbuilt in the near future, go for it.  I tend to ride my technology to the bitter end, so for $20 it was worth it to me.

Never tried an Eye-Fi.

Lenses / Re: Any word on the 50mm with Image Stabilzation?
« on: June 19, 2014, 12:47:36 PM »
Now we have comparatively insane ISO capabilities.  You don't need 1.8 to get a viewable picture.  The only reason to have 1.8 is the depth of field and bokeh.

Respectfully disagree -- there is one reason you forgot.  Low light with moving subjects requires fast glass -- IS doesn't do a thing for that.  Lenses for indoor events like sports and concerts need all the speed they can get.  I recognize the 50 F/1.8 is not a sports lens for a boatload of reasons, but you get my point.  What my brother (more on the novice end) can't capture at a school concert with his kids with his kit 18-55 crop zoom can be better pulled off with his nifty fifty.

And though we can use high ISOs on DSLRs these days, not everyone likes climbing up to ISO 3200, 6400, and beyond in poor light.  It's useable, but it's simply not as good as a shot at a lower ISO.

Seriously, this is Canon.  Do you really believe they want to keep offering us a great deal on a cheap lens, when they can offer us a good deal on an affordable lens (the 40) and a rebate/MAP deal on a second (one of the 50s)? 

I'm torn on this one.  Evil-Big-Corporation Canon (who punishes us often with new lens prices) would do exactly what you've said.  But Thoughtful-We-Are-The-World Canon seems to have protected two lenses as mass-produced, cheap, sharp plastic lenses -- the nifty fifty and the kit 18-55 (revised a good 5-6 times by now).  Both are marvelously sharp for the dollar.

I think Canon would rather make a III version of that EF 50 F/1.8 lens -- possibly with STM (no chance with IS) and keep it reasonably priced, say $150-175 -- than obsolete the nifty fifty altogether.  As much as we're sitting on a gear-obsessed forum, they need a reasonably priced low end to their lens offerings for novices and those on budget.  Canon isn't Leica, after all.

  • The 40mm Pancake is not part of a '50 prime ecosystem' in my mind.  That's its own animal.  Throw the focal length out for a minute.  I just think the pancake is an odd duckbill platypus of a lens experiment -- will people use a focus-by-wire little guy with few common lens creature comforts?  I see it like a soft focus or a 1:2 Macro prime -- just a unique little creature.  I'd leave it out of a pricing tree discussion, personally.
  • You may be underestimating the Canon 50mm F/1.4 user base.  That is the sharpest 50 Canon sells.  By F/2.8  or so, it outclasses the L.  So the L is relegated to portraiture / art / small DOF work, and the 50 F/1.4 is the more-general-use lens that I see in pros hands at events, in photojournalists hands, etc. And I think this is the Canon userbase that is screaming for a better do-everything option in the 50mm segment. This group probably just wants a modern 50mm F/1.4 II more than they want a 50 IS, but if the new 50 IS gets them the IQ improvements, internal focusing, build quality, true USM focusing speed, etc. they will gladly pony up the money on day one.  This is the largest pent up demand segment in Canon's prime universe, I believe.
  • So my vote is to buck the trend of eliminating the Group 1 lenses in just this focal length.  Offer the new 50/(whatever) IS and replace the 20 year old 50 F/1.4 that many folks are stuck with as their best option.
  • I think it will be pricey at first as Canon snatches up all the pent up demand from the current 50 F/1.4 user base -- say $750.  But then it should walk down like all the other IS refreshes have.  $500-600 seems about right.

All good points.  I do wonder, though, if entry level users are actually get the nifty fifty and using it in those low-light situations (indoor sports, theater).  I was more under the impression that they were just turning on the flash and wondering why things were blurry.  I'm not really in those settings now, so I don't know.  But the people who buy $100 lenses don't know the difference between 6400 and 12800 ISO.  Once they do, they are committed enough to pony up a few more bucks for the "Group 2" lenses that meet their needs.  Also, the part in red about wanting a new 50mm 1.4, I agree 200%.  I just think that Canon is content to move more slowly on the Group 2's and start with the Group 1's first.

I wish we were voting!  We only get to vote with our dollars, euros, yen, which means we only get to vote after the products are released, not before.

Software & Accessories / Re: Inconspicuous Messenger Bag
« on: June 19, 2014, 10:26:39 AM »
If you want a messenger type bag that does not look like a camera bag, I would recommend not buying a photography messenger bag. 

I would use The Googles and look up the manufacturers of messenger bags.

The problem with regular messenger bags is they do not normally come with the padding to protect your gear and the compartmentalisation system required to stop it all rattling around together.


Search amazon or B&H for "camera bag insert" (http://www.amazon.com/s/ref=sr_nr_n_0?rh=n%3A502394%2Ck%3Acamera+bag+insert&keywords=camera+bag+insert&ie=UTF8&qid=1403187843&rnid=2941120011). Then just put that in whatever regular messenger bag you want, so long as it can support the weight.  The problem you will have is size and weight.  For a 5dIII and the two 2.8 zooms, you're looking at a bit of both.

Regarding the nifty fifty, I just think that Canon is showing a clear trend away from the wide aperture lenses as entry level.  I'm not saying they are going to announce tomorrow that the current 1.8 is out of stock everywhere.  I just think that production will quietly be stopped and once the current stock runs out, it will be gone.  The 50mm 1.8 originally was meant to be used with film cameras where you sometimes couldn't get anything unless you had 1.8 light.  Now we have comparatively insane ISO capabilities.  You don't need 1.8 to get a viewable picture.  The only reason to have 1.8 is the depth of field and bokeh.  I think Canon would rather use the 40mm 2.8 as the "gateway" lens to that, because 1.8 is not easy to work with.  After they've sold you the pancake at $150ish and you've figured out how depth of field and focusing works, then they sell you the 50mm 1.4 or the 1.8 IS at $350 or $550. 

Seriously, this is Canon.  Do you really believe they want to keep offering us a great deal on a cheap lens, when they can offer us a good deal on an affordable lens (the 40) and a rebate/MAP deal on a second (one of the 50s)?  I would love to see a 50mm 1.4 with IS added, but I think that is wishful thinking.  I just looked at B&H for the rest of the 50mm full-frame lenses with IS, and there aren't any.  So Canon is going to do whatever the heck they want, because this is going to be a unique product.  Because they can't add IS to a 1.4 and compete with the new Sigma Art or the Zeiss Otus on sharpenss and image quality, because it would cost too much.  I would have also rather seen the 28mm IS at 1.8 rather than 2.8, but it didn't happen that way.  They even went so far as to have the IS wide primes at 24mm 2.8 and 28mm 2.8, rather than create a meaningful distinction between the two (i.e. wider but slower, faster but less wide). 

Which is just a long way of saying that I think they are going to cull the "Group 1" non-USM primes in this IS update, and then we'll see something else happen to the "Group 2" USM primes (good or bad, I don't know).

Also, I think that the Sigma Art 50, the Zeiss Otus, and Nikon's 58mm recent offerings have pushed Canon's IS update back here.  Canon wants to let some of the hype die down before they get out there.  Because people are clearly clamoring for this thing and complaining about the lack of qualify 50mm options in Canon's lineup.

I think the consensus here is correct, but I will say this -- I am almost certain that it will be a 50mm 1.8 IS, that the current 50mm 1.8 II will be discontinued (with its entry-level fast prime status handed off to the 40mm), and the current 50mm 1.4 will stay for now (like the 28mm 1.8 alongside the 28mm 2.8 IS).

The 85mm (and higher) IS options are a bit more puzzling.  The 135mm 2.8 soft focus has basically been phased out, and that could be an excellent candidate for replacement with IS since it doesn't have USM and the only other 135mm is the non-IS L.  There are no similar options at 85 or 100.  Both of those non-L lenses are USM, seem to be popular.  I could see Canon adding an 85mm IS option at a price point between the USM and the L, maybe at f/2 or f/2.8.  I don't know about that for the 100mm, since that slot already has the fast 2 USM, the macro 2.8 USM, and the macro 2.8 IS USM L that is relatively affordable.

And I don't think anybody knows what Canon is going to do with their fast USM non-L primes (the "Group 2" in ahsanford's post above).

The viewfinder stays powered with the camera switched off, how much other stuff is powered whilst off, GPS on 6D?

The viewfinder in a traditional SLR or DSLR is a prism that reflects the light being transmitting through the lens and bounced off the internal mirror.  Hence, no power is required.  The GPS on the 6D stays on while the camera is powered off so that it can keep updating its own location, unless the GPS is deactivated first.

No ideas to share, but don't wait.  We just lost our older dog unexpectedly, and we treasure the quick family portrait with our dogs that I took at Christmas.  We had been planning to visit a studio with the dogs and kept putting it off.

Canon General / Re: Buying refurbished from Canon
« on: June 10, 2014, 05:37:24 PM »
Good experiences all around for me - most of the gear has appeared brand new or with very minor wear.  I hate having to pay the sales tax, too, as that ruins the savings many times, but there is another source of the very same Canon refurbished gear without pesky sales tax for most of us - Adorama.  The selection is very limited and the pricing can be lousy or great, but keep an eye on it and you're likely to find something.  I've bought a 180L macro and 2x III extender from them and both arrived in the very same packaging as the refurb gear directly from Canon.


B&H also sells Canon refurbs, look for them in the used department.  I bought my 6D that way, it was listed as manufacturer refurbished, and came in the expected red and white box with Canon logo and sticker, just like my 40mm that I bought directly from the Canon refurb store.
