derfotograf: This is modern America.

When I finished my studies in America 45 years ago, it was a totally different country. Today it is ruined by lawyers and rude companies...

But please don't complain. In Spain there is a saying:

Necesitan dos para joder. (You need two to have intercourse).

So it's up to you if you want to participate or not. I definitely won't.

Did the Argentinians change that to:

"Necesitan dos para tango."

If candy-colored cameras is your thing, there are camera manufacturers who make them in shiny candy-apple red, green, blue, etc. The maxim I grew up with, "the best camera is the one you have with you" favors cellphone cameras because it's the Swiss Army knife of electronics. And for those who say that dSLRs and compact cameras get better as fast as cellphone cameras, I don't agree. Cellphone cameras get better faster. That's why there's a big dip in camera sales. Net, net: I don't think this Silicon Valley fantasy business will fly. They should just start selling those cool, candy-colored leather cases. That'll fly for sure.

In reply to:

Adamant: Can someone link to an example of medium-telephoto (135mm) tilt-shift architectural photography? I keep seeing people say these are useful for such things, but I am having a genuinely hard time envisioning it. I promise I'm not being combative here. I really don't think I can understand without an example or two.

I get why tilt-shift is useful for architectural work at shorter distances and I get why it would be useful for product/macro type work. But the medium-tele architectural stuff escapes me.

These lenses are also useful for non-macro product photography (think pizza slices, circuit boards, and computer motherboards) where the flat object lies more perpendicular to the sensor plane and you want more depth of field to get the whole object in focus. I have used the 80mm Hartblei SuperRotator for this to good effect.

On article Canon EOS Rebel SL2 sample gallery (229 comments in total)
In reply to:

George Veltchev: almost an hour after the release of this article we have ' 0 ' comments !!! ... damn I was refuted when claiming that Canon 6D Mark II is the most boring camera for this year ...

It's not the camera that's boring. I'm sorry to say it's the snapshots. These images largely do not push the SL2 to any extent, even if they are absolutely typical of the kinds of images 99% of the SL2 owners will eventually take.

On article Hands-on with Canon EOS Rebel SL2 / EOS 200D (235 comments in total)

I use my tiny and light SL1 as my main dSLR 80% of the time, relegating my tank-like 60D to especially challenging situations. The SL2 will undoubtedly replace my SL1 as soon as the SL1 hiccups, dies, or ceases to exceed my shooting skills (which it still does by a wide margin). Certainly I'd like a 19-point focusing system so that I could ignore 18 points instead of the eight I already ignore (or 51 points so I could ignore 50). The "fastest AF in the world" is a win. The full-sensor, live-view, dual-pixel AF is a win. The bendy touch screen is a win. The image sensor is a win. The 1080p60 HD video is a win. The DIGIC 7 processor is a win. The minimal size increase is a win. (And yes, I'm sure the pixel-peepers will deem this new Canon body "crap." That's sort of a win too. I can't wait until they fill up Canon's refurb stock with "crap" SL2 bodies. Please. Please.)

On article Video: Removing a stuck lens filter... with a band saw (139 comments in total)
In reply to:

Entropy512: I haven't gotten through the entire video yet, but this is from the category of "I'm an electrical engineer, not a mechanical engineer, and I know that's a HORRIBLE design" with regards to that "filter wrench".

Since the filter wrench is threaded, torquing it in the same direction needed to remove the lens will result in (exactly as happened here) the wrench coming out.

A proper filter wrench needs to grip the filter from the outside.

That's because the tool Adam has purchased is not a filter wrench but a thread reformer. It's designed to put a filter ring back into round through gentle pressure after you pound a flat into it. I've watched demos of this particular wrench on YouTube. Adam Savage is truly a genius in the shop, proven time and again, but this time he tried the wrong tool--and it didn't work.

On article Throwback Thursday: the Olympus C-2100UZ (130 comments in total)

The UZ was my second digital camera but first serious one. I had been a Canon film SLR user for decades (since the FTb) but could wait no longer for Canon to go digital. The Oly UZ was a terrific camera and took great images with the sole problem of very bad shutter lag so capturing things like sports shots was hard. This camera gave me the experience needed to help me pass by Canon's first digital SLRs. They all had shutter lag until the 20D, which handled like a film SLR. I immediately bought the 20D and retired the UZ. I still have my UZ.

On article Corel PaintShop Pro X9 arrives with improved workflow (48 comments in total)

I have used Paintshop Pro for 20 years and liked it. I'm using X7 right now. I've always found its user interface much easier to understand than Adobe's. Truly, I do not use the tool to a great extent. I find two clicks, the Smart Photo Fix and high-pass sharpen, will usually (but not always) get me 95% of the way there and usually don't bother with the other 5%. When I need extra help, saturation and curves adjustments are easy too. Price is right, usually less than $50 if you wait a few months after intro. The big downside: the advertising nag screens have been getting progressively more troublesome and Corel seems determined to hide the way to turn this off. They change the procedure for ridding yourself of these advertising screens with each new version so you have to wait for someone to figure it out. Meanwhile, its really, really irritating. That said, Paintshop Pro is an essential product for me in my daily work flow.

DamianFI: Who leaves important gear, worth $10K mind you, out of their site in a foreign country they know is rife with thieves?

Guy's a nincompoop.

Cameras left at the office take no photos. Organized thieves practice long and hard at their trade. This loss is no reflection on the photographer. We're all prey in this sort of situation. Sounds a lot like Barcelona, where street crime is rampant and "gone in 10 seconds" is common. Google it. you'll find 100 street scams all carefully worked out and documented.

Jonathan Brady: I honestly don't believe that Canon PURPOSELY tries to limit 3rd party lenses and accessories from communicating with their cameras. I truly don't. What I do believe is that they don't care AT ALL, if they make it to where they don't. Which is fine. They don't guarantee that 3rd party accessories/lenses will work, the 3rd party companies do - so it's on the Sigma's and Tamron's of the world.
But... I do feel like at least a few people at Canon, Inc are LAUGHING THEIR B***S OFF right now! hahahaha!
Having said that... I'm glad my Sigma 50 Art works with my 5D Mark III :-)

I agree with Jonathan Brady. If Canon started to worry about 3rd-party lens compatibility, then there'd be no end to the engineering mickey mouse needed to ensure all those reverse-engineered interfaces worked. In fact, Canon would have to reverse-engineer the reverse-engineered lens interfaces from Sigma, Tamron, etc. Makes no economic sense for Canon to do that.

In reply to:

Biowizard: There was a time when a camera simply measured the actual light coming in through the entirely passive lens, adjusted for the reported aperture setting (trasmitted via a mechanical lever), and made the perfect exposure on a fixed-ISO sensor (called film).

Frankly, the idea that a LENS needs firmware is appalling. So many lines of computer code trying to compensate for manufacturing shortcuts which, once upon a time, were sorted by decent design, gear reductions and the pitch of helical-cut metal.


I'm not sure how you get autofocus and aperture autoexposure without electronics in the lens. In the all-mechanical days, your fingers did the focus and aperture setting. As it turns out, lots of people like autoexposure and autofocus, so you pretty much need to smarten the lens with electronics. Now, if you want to use those old, all-mechanical lenses you can! Your fancy latest-model dSLR will accept these lenses and your fingers can do the magic like always. I've got a few manual lenses and they work fine. But if you want auto, then electronics are a must.

As for compensating for lens-manufacturing deficiencies that weren't there in the good old days , that's just not the case. Today's lenses need to resolve much better than the old ones to meet the needs of 20+ Mpixel sensors. Old lenses were designed and built to resolve down to the grain size of film. Even Kodachrome, the gold standard for small film grain, did not have the resolving power of today's top image sensors.

I regret Sigma's problem but this sort of thing has been going at least since Canon adopted the EOS EF mount for it's digital cameras. I once bought a Sigma lens that only worked on Canon EOS film cameras by mistake. That's when I learned that the 3rd-party vendors had to reverse engineer the Canon EF (and later EF-S) mount. Canon knows the shape of the electro-optical envelope of its EOS mounts and the camera-lens communications protocol and is able to update lens technology with things like multiple IS generations, ultrasonic focus motors, and STM's focus-by-wire. The other vendors can't. They don't know where the edges of the mount's envelope are. As a result, the only non-Canon lenses I buy these days are full-manual lenses with no electronics at all. Yes, I miss out on some really fine 3rd-party glass. I can live with that.

Hey Ken Philips. Here are my lenses that cost less than $175:

Canon 50mm f1.8 Mark1
Canon 28mm f2.8 pancake
Canon 40mm f2.8 pancake
Canon 55-250 zoom

None of these lenses are dogs.
