The least persuasive case is for Portrait Photography where your subject is not moving and stays quite still, since a half press of the shutter will usually do an excellent job of autofocussing (with single AF point) without any tracking, possibly far better than tracking.

However, if you are doing re-framing, such that the focus point such as the eyes move around a lot, the tracking could save you some time, if it is really accurate.

I loved looking through the photos with the accompanying text. Most people, including me, forget the painstaking detailed work whether performed by hand or cleverly automated.

It's incredible that the smartest people in the world have improved understanding optical principles and have devised practical solutions to build such amazing devices.

Of course we must not forget that we have not discussed the complicated processes of creating the raw materials, namely optical glass, plastic and metallic parts that are needed to fabricate a lens. Plus, very special lubricants, cleaning fluids, adhesives etc.

I almost left out all of the microelectronic processing components and memory !
I'm certain to have left out other things too...(lens coatings etc.)

Thanks very much !

Very interesting article featuring some very capable people.

My favorite Canon lenses are:

1) Canon 70-200mm /F4L (my sample was incredibly great, possibly better than my IS version of the same

2) Canon 70-200mm /F2.8 II IS because it is faster, although much larger and heavier

These two are excellent for portraits and fashion in general. The zoom feature allows me to frame very rapidly without having to change the shooting distance. Also at the telephoto end you can blur the background very easily.

I don't like zoom lenses where the aperture changes so the exposure must be adjusted, which is especially an annoying problem for video.

What I absolutely hate is are the celebrity photos of women taken with wide angle lenses which distort feet to make them (the feet) look vertical like on a puppet. It's really horrible !

cdembrey: Very strange. Why would thieves target camera stores? American camera stores are going out of business due to lack of sales.

The thieves are photographer fanatics with expensive tastes, not willing to work and save up to purchase these goods.

Jan Frojdman,

Incredibly Beautiful and Exquisite, It's like going to Heaven for anyone who has ever dreamed of visiting Mars. It's rare that Artistry is so well combined with Scientific Accuracy and it looks like a perfect marriage.

You have created an artistic Masterpiece with gorgeous music to accompany the wonderful visuals.

Congratulations on creating a Masterpiece ! And thank you so very much.

Dan

On article Sigma releases price and availability for sd Quattro H (369 comments in total)
In reply to:

Dan Tong: Congratulations to Sigma for this unique camera featuring the novel Foveon Sensor for keeping creativity alive. Along with Fuji, who also have designed a unique sensor, they have avoided the far safer "Me too" approach and have pushed technology toward constant improvement.
I sincerely believe that multiple approaches for tackling any problem are far more likely to result in surpassing yesterdays best, than a single path toward that goal.

Innovations of this type, as well as Pentax K1 shift technology, are needed to further improve photographic technology, and too many of these innovations are not coming from the biggest market share (richest ?) players such as Canon, Nikon, or the upstart Sony.

Perhaps many of the cameras that leave off the Bayer Filter, have been inspired by the Foveon Sensor.

-Continued

The Sigma sd Quattro H sounds very exciting, and if I read things right, appears to increase dynamic range by combining multiple exposure readings in a single DNG RAW file.

In contrast to the whiners and constant naysayers, I applaud and value these novel products and ideas.

Thanks for reading.

Dan

The video looks fantastic, probably due to the excellent color grading. I can well understand why Richard Butler finds this camera so appealing.

Excellent IS performance.

The reason is that the people making this decision are MORONS.
End of story.

Pierre Louis: According to the pictures, the GH5 will have the same design flaw that plagues the GH4 and GH3. Watch this to find out more and speak up to let Panasonic know you want this flaw fixed once and for all!

Absolutely RIGHT. The microphone input gets in the way of the display screen, and his suggested alternate position makes sense. View the youtube video for details, and if you agree please add your voice to this request.

The GH5 is the new camera I'm most interested in at this point, so I'm eagerly awaiting it's full debut and hope it lives up to our eager anticipation.

Best of luck to Ms Highsmith I hope she wins the full amount.

I filled out some answers to the founding member pages just to see what questions they asked etc. and found that after choosing Video, Pro level, they asked what was the subject of the work and they had Portrait, Editorial etc. almost all dealt with still photography, with very few choices relevant with Videography and filming (such as independent films).

Like too many other companies, the people that Parachut put in charge of this survey/questionnaires, do not appear to be familiar with the somewhat different scope of still vs video photography, the very reason for filling out these forms.

The company sounds interesting but if it is run by amateurs, to the extent that this experience suggests, they're not likely to be successful.

Here's my suggestion to Parachut, find competent people to do each task and then test everything, over and over until it works otherwise you're going to crash notwithstanding your company name. Best luck, in any case.

On article D500 owner formally accuses Nikon of false advertising (473 comments in total)

Truth in advertising is an important concept, but unless it is enforceable it is pretty meaningless. The description is misleading.

This has nothing to do with the qualities of the camera, or of Nikon's innovations, and it applies to ALL COMPANIES. We want the truth, not BS.

On article Pentax K-1 Pixel Shift Resolution: Updated Field Test (211 comments in total)

Pentax is a seriously innovative company that pays more attention to photographers than most other companies. The Pixel-Shift feature is great, as long as you know when to use it.

I can think of only 2 or 3 really useful features introduced by the Subscription PShop since CS6. So much for the promise of not being limited by the update cycle of the standard purchase model - just total BS.

I have not subscribed and just use PShop CS 6 and based on the announcements here, I don't think I'm missing much based on "my use" of PS, your experience may differ.

The sharpening feature (useful mostly for movement blur), is now available in PS Elements (the cost of a plugin when on sale) a feature which I found far less useful than I hoped. I expect Content Aware Cropping to be available on PS Elements soon, so if you really want it, that's one way you may be able to get it without subscription to PS.

I'm sorry to hear about his ill health and passing. His columns were always enlightening, and practically focused on the usability of cameras as tools to do art.
