On article Tamron files patent for 115mm F1.4 VC lens (34 comments in total)
In reply to:

CameraLabTester: On a Full Frame camera, at a distance of 10 feet, the DOF would be 2.26 inches, just enough to get half of a face into focus.

On a cropped sensor APS-C camera, at the same distance of 10 feet, the DOF would be a sensational 1.43 inches, just enough to get the eyeballs into focus!

New boyz and brett nz have it right.

If you stand 15 feet away, you will get the whole face but the dof will be larger.

On article Brooks Institute announces closure (130 comments in total)
In reply to:

ewelch: I checked official numbers, their default rate is 10.8 percent and their default rate was 36 out of 330. Acceptable numbers. There's more to this story.

Sounds like the "government loan" story is just a red herring. Probably they can't make a profit given their drop in enrollment.

On article Brooks Institute announces closure (130 comments in total)

Looking at the link, it seems the article left out some details.

"Under the regulations introduced today, a program would be considered to lead to gainful employment if it meets AT LEAST one of the following three metrics: at least 35 percent of former students are repaying their loans (defined as reducing the loan balance by at least $1); the estimated annual loan payment of a typical graduate does not exceed 30 percent of his or her discretionary income; or the estimated annual loan payment of a typical graduate does not exceed 12 percent of his or her total earnings."

These criteria are much less harsh then the article suggests.

On article Still solid: Fujifilm X-E2S Review (228 comments in total)
In reply to:

By standing on the Shoulders of Giants: Fujifilm seemed like they have used the SAME sensor on like 5 dozens types of their camera.

You're right, and I think its a good strategy. Advantage for them they get to concentrate and amortize all sensor related R&D. Good for the consumer, they know what they are getting accross the product line and choose camera based on other features.

Nikita66: sorry if this is a dumb question, but what, exactly, is Nikon AE mount?

AI mounts use a mechanical lever. AE mounts use electrical contacts.

On article Getty Images sued again, this time by Zuma Press (68 comments in total)
In reply to:

AbrasiveReducer: I hope McDonald's hasn't trademarked this phrase, but "I'm lovin' it".

Hate to burst your bubble, but the USPTO has given the I'M LOVIN' IT trademark serial number of 78257217. It was registered on 6/13/2006. Expect a letter from Getty, demanding you pay them a license fee for posting this. The fact that they don't own the trademark, that Macdonalds does, won't stop them.

Getty has technology that searches the entire internet for images that are in its database. Yet it doesn't search the library of congress, or other stock agency databases for images that it "acquires". I think lawyers call this willful blindness. And thats being generous.

Gesture: At this Pro level, which is better: writing to Compact Flash or some form of SD cards?

Cf cards are harder to misplace.

In reply to:

shooter mclens: I had the S5100. its best feature was the 10x zoom. it would have been an excellent camera had it offered more direct controls, but it was decent for that time. i cant recall if there were even any 6mp cameras back then, and the consumer DSLR was still years away. I remember taking that camera to Africa. Fuji has always made pretty good cameras.

The 300D was the first consumer DSLR, had 6MP and was introduced in the summer of 2003.

Nikonandmore: Amazing that in 12 years camera design hasn't changed A BIT!!! Specially the Superzoom S5500. There are new cameras today that look exactly the same.. too amazing..

Camera design hasn't really changed from the film days. I guess thats because human design hasn't changed.

I suspect you must be right.

Unfortunately the commlite/vello does not seem very reliable. Doesnt support many lenses, slow and inconsistent with others:

Novoflex makes a smart adapter that will control aperture. will set you back $300.

Can't wait for someone to build a reliable auto focus F mount to E mount converter.

On article Accusations fly over Fukushima photos (88 comments in total)

I think the photos are much more interesting now. Without the controversy, they are just bad snapshots.

On article Sony prices 70-200mm F2.8 GM OSS G Master at $2600 (211 comments in total)

25% higher list than the competing offerings from Canon and Nikon? Yes, I get that those offerings are "old". But so what? Are Sony's optics demonstrably better? Is the IS better?

In a similar vein, their teleconverters are listed 10% higher than Nikon and 25% higher than Canon. Don't tell me their tc optics are superior.

I'll note the 24-70mm Gmaster benches comparable to the equivalent offerings from Canikon. A tad sharper at the center, a bit more astigmatism, basically a wash.

On article Lens shootout: Sony RX10 III destroys the competition (487 comments in total)

"its faster maximum aperture helps it combat diffraction. Remember that F4 and F5.6 on 1"-type cameras are equivalent to F11 and F15, respectively."

Very good point. Is the rx10's superior performance over the g3x attributable to its lower diffraction? Coming from FF, I've always stayed away from f16 for just this reason and prefer to keep at or under f8

With the fall of the inluencers, there has been the rise of the micro-influencers..Instagram influencers with 10,000 to 100,000 followers. But they too shall fall to the nano influencers.

Seems we are coming to the day when adverstisers will just pay individuals who are personally in the market and are about to make a purchase. Coming full circle, they will discover the power of using their marketing budget towards discounting the price.

Michael, you will always be with us through the impact you have had on us all. You uniquely brought together, and advanced the understanding of, the technical and artistic aspects of photography.
