Speedlites, Printers, Accessories / Re: Lexar CF cards FAIL - Sandisk?
« on: April 07, 2014, 02:05:40 PM »
It could be the case that you have fake Lexar cards and that's why they are failing. Lexar, Sandisk, Transcend are all really well known firms and I have never heard that their production is failing (massively, as in your case).

Had a Sandisk disk-on-key fail out of the box. Couldn't copy anything larger than ~100KB to it.

Had an Intel processor fail straight from the shop, failing to install three different versions of MS-Windows from five different CDs.

This is a well known phenomena, which is why it is good practice to test memory cards before using them for anything of importance.

EOS Bodies / Re: Canon's Medium Format
« on: April 02, 2014, 08:41:44 AM »
The whole "eqivalent megapixels" deal that Sigma uses is also very misleading. Currently, today, megapixel counts are based on output image widthxheight. A 15mp Sigma Foveon is 15mp, in terms of actual megapixels stored in the output JPED image or a JPEG that you can create from RAW. It may have 45 million photodiodes, but that is not the same as megapixels, and I really wish Sigma would stop being so misleading.

No more misleading than stating a sensor has so many megapixels, when each photodiode samples one color, and the other two are interpolated in the JPEG.

Probably an April Fools, but I still find it more credible than the rumors about Canon purchasing a MF manufacturer.

APS-C & EOS-M made sense because (a) those are big markets, and (b) Canon's FF lenses could be mounted on those cameras.

What would be the benefit of making MF cameras? Selling a small amount of cameras with another manufacturer's mount? Making a whole new line of lenses, rather than investing resources into some other line which benefit it more, e.g. EOS-M?

Lenses / Re: New EF-S 24mm & USM Motor Coming? [CR1]
« on: March 28, 2014, 12:58:44 AM »
Is there a particular reason that makes EF-S cameras need (dedicated) 24mm lenses?

Is there any reason FF body shooters need a dedicated 35mm lens?

An EF 35mm lens will work fine on crop bodies, as will an EF 24mm lens, e.g. the new 24mm f/2.8 IS USM.

An EF-S 24mm f/2.8 IS STM will not work on FF bodies, hence it's being dedicated crop lens.

Third Party Manufacturers / Re: Patent: Tamron 10mm f/2.8 Fisheye
« on: March 26, 2014, 02:27:21 AM »
Wondering if it would be for Full frame or cropped sensors...

It's focal length is close to 10mm and half angle of 90 degrees, so it looks to me like a diagonal fisheye for crop.

Shouldn't the electronic contacts be visible across from the red points?

This is a machine vision camera, and those typically are used with dedicated lenses (fixed focal length and aperture and often a fixed focus distance).  No electrical contacts are needed, which is why you're not seeing them.

The text has a line about EOS lens compatibility, so I'd expect contacts for aperture control, etc.

Considering the left lens' bulbous element and small hood, I'd guess it's wider than 10mm.

Edit: then again, it looks like knobs on the barrel - maybe a tilt-shift lens?

What's "Shifutobure"?

Because I want my friends, or my friends' friends to see the photos.

E.g. I've seen a band playing jazz music in a street with half a dozen people dancing, took photos, and posted some on my web page to share a bit of the experience with my friends. Shared it on the band's FB feed, and the people who danced (apparently fans of the band) tagged each other. Apparently they wanted to share the "been there, enjoyed that" story with their friends as well.

EOS Bodies / Re: Is Dual Pixel Tech Coming to the EOS 5D Mark III?
« on: March 08, 2014, 01:05:17 AM »
I wonder why did Canon introduce the EF 40mm STM in 2012 if it had no plans to introduce a FF camera with DPAF shortly after that?
Not quite making the connection there...care to enlighten?

-pw

All the other lenses with STM are EF-S, and work with APS-C bodies that have DPAF.

Why would Canon make a FF lens with STM, if there are no FF body owners to buy it?

EOS Bodies / Re: What Happened to the Photography Industry in 2013?
« on: March 06, 2014, 04:31:26 AM »
IMHO, we should also be looking at what happened in the years up to the peak.

In 2000, Canon wasn't selling any DSLRs. In 2010 Canon was selling the 5Dmk2, an FF DSLR that can shoot video at an attractive price point. Point being, people were moving from film to digital, and that helped sales. Now that the market has reached maturity, it's only natural sales would slow down, and smartphones & the economy just help to roll sales down the hill.

My guess is the new non-L 24mm, 28mm, & 35mm IS USM are first signs of Canon realizing it has to tap the lower end DSLR market to make money, as in most rebel owners aren't going to upgrade to FF or buy L lenses.

"Will still photography be necessary in the age of 4K video?

No, because you can just select the frame you want and it will have sufficient resolution. Now you only need a flash system that does 30 full hss bursts per second and lasts for some hours w/o overheating and power drain :-> ... that's why I'm happy with my 3fps  6d.

A) I was mocking the resolution based argument the interviewee was making.

B) Plenty of photos are taken without a flash. Last two family events I went to took place outdoors in full daylight, so I didn't even bother taking a flash with me.

C) Flashes like the 320EX solve part of the problem.

So, will still photography be necessary in the age of 4K video? Yes, 4K can eat a nice chunk out of it.

"Will still photography be necessary in the age of 4K video?

[GT] Somewhere in the future, maybe the two things might converge but currently with 4K technology you're talking about an 8MP still image, and with 20-30MP stills cameras being the norm I don't know whether 8MP would satisfy someone's needs."

Cause nobody can't compromise on prints sized A5 and smaller anymore? Damn...
