On article Nikon D7500: Should I upgrade from my D7200? (292 comments in total)
In reply to:

TGThomas: Say No to Nikon. First, I thought I am going to upgrade my D7000 with this one, D7500. OK, there is only single slot for memory card -- I can live with that. Then, there is no vertical grip/power bank. Hell, No. I am going to dump Nikon and the full line of pro lens I have for years. Nikon sucks, treating its loyal users like dumb ass by ignoring basic needs. They think they either force to spend more money on a camera or let you live with a bad feeling with a camera without a basic function at its level. Say NO to Nikon.

What happened to the D7300 and D7400? The D500 is released (April2016) and THEN the D7500 (April 2017). Yeah, nice sequencing logic and timing.
The irony is that the D7500 competes with the D7200 price point, so which D7x00 fills the D750-D500 gap at $1600?

Nikon's business strategy fits this here and the other there, but I'm the serious amateur struggling to afford a good camera (which will never pay for itself), which depreciates quite quickly. Nikon adds to the price pot, making the purchases sweeter (like an articulating screen or a flash-sync port) or subtracts (no CLS for you, cheapskate).

My (ignorant) perception is that Nikon assumes the client will equate extra features with cost; my gut feel is that if there is no real cost (to Nikon) to include certain features, the price should not escalate.

I'm not getting a client-centric feeling. Starting to think No to Nikon.

On article Nikon Coolpix A comparative review (18 comments in total)

I'm using the DPReview Camera Feature Search, and the results for Nikon seem astonishing. Nikon sells Compact & Premium cameras, but not 1", 4/3 or FF (all in the Fixed Lens category). There is 1 APS-C camera, the Coolpix A. No Nikons have a gold award in the Fixed Lens Category. One wonders what Nikon's strategy is and how product costs and sales are interpreted. I'm aware there is a new strategy on the horizon to focus on DSLRs, but I am still surprised that the high-end technology did not filter to the smaller consumer cameras. No gold awards in the Fixed Lens category.

Earthlight: My respect for Sigma only continues to grow. They do so many things right.

Not me. I'm concerned about the 'lucky draw' when buying a Sigma, as well as the transparency behind number of lenses returned.
I'll stick with DxO ratings when making a purchase, but wonder if lenses tested at point-of-purchase versus after continual use (e.g. 10 000 photos) will show the same results.

Disappointing article. Did the author actually compare notes with Nikon's Marketing and/or R&D dept.

In reply to:

Biowizard: Seeing the numerous responses to my earlier post about sensor sizes ("Can someone remind me - just HOW big is a '1 inch' sensor?"), several people suggested something relating to the 135 format (35mm, "Full Frame", actually 35mmx24mm, or about 43.25mm diagonal).

This makes sense to me too, but most folks suggested something relating to the _area_ of the sensor: however, this is now how anyone currently thinks. All those "35mm equivalent" and "crop factor" quotes beloved of this website, are _linear_, not squared.

Of course, we also need to know the aspect ratio, as there is a heck of a difference between formats, from square in the medium format world, to 16:9 in default modes in some consumer cameras.

So my suggestion is this: treat 135 as the "standard" full frame, and using its diagonal as the standard reference point, notate it as:

1.00/3:2 (1.0 diagonal, 3:2 aspect ratio)

4/3rds, with a diagonal of about 21.65mm, would be:

0.50/4:3 (0.5 diagonal, 4:3 aspect)

I'd like to add another example of a sensor size,
E.g. RX100 1" (13,2*8,8) = 116, where the diameter is 15,86mm, and an inch is 25,4mm. I'm aware of the origin of the 1" term, but it's applied inconsistently (and underhandedly).

pieranti: I traveled with a Canon Powershot G15 that did not disappoint despite the sensor size. http://www.dpreview.com/galleries/5195451339/photos/3188787/img_2003

I travel with the Canon S95 (same sensor size as G15). Very handy, pocketable camera. DPReview Side-by-Side can be more accurate and complete e.g. in low light the S95 ISO extends to 12800.

I like what Brian says.
Does abstruse terminology assist the practitioner or the potential buyer; I suspect the latter. Sensor area, 135 format, diagonal, image circle diameter, all terms but with each camera test and after reviewing the specs I'm recalculating the given info to a consistent standard.
To add to Brian, perhaps the surface area (in mm) might be a simple guide, as a standalone or as additional info to diagonal & aspect ratio.
E.g. 135 sensor size (36*24mm) = 864
E.g. Canon S95 (7,6 * 5,7) = 43
E.g. Nikon D5500 (23,5*15,6) = 366
E.g. Medium format (56mm x 67mm)=3752

On article Real-world test: Nikon D750 at the Museum of Flight (280 comments in total)

Not sure what to think of this video. It's a hardsell for Nikon.

I would prefer a sober evaluation, e.g. by Thom Hogan (bythom.com) and critical comparative image evaluation (e.g. photozone.de).

The video disappoints: 1920 x 1080. Perhaps next year Nikon will match the Panasonic GH4 (4096 x 2160 (24p), 3840 x 2160 (24p, 25p, 30p)).

DP Review would do well to find new grades of photographic competence, the integrity of which cannot be imitated. Yes, so I went overseas, took some pics, gave my opinion to someone at a bus stop on a certain camera; now I'm ALSO an international traveler, street photographer and lecturer, and this is backed up by my links on Twitter/ Facebook.

The title of this 'essay' is misleading, and the pics are horrendous. Any integrity of this piece goes to the book he's reviewing, not himself. The subject of choice, purchase, cost and benefit is important, but must it come in this packaging?

I suspect this article will find its way into the same basket as 'Professional advice on Street Photography' because it's been on DPReview, and this is grossly insulting to the damn fine contributions made by other photographers in the field.

Graphics Interchange Format is abbreviated to GIF, which is also an acronym.
The purpose of abbreviations and acronyms is, inter alia, to promote efficiency in referring to concepts, but the general rule is that the sound of the letters in said abbreviation goes back to the words compiling the concept.

As much as the world is grateful for the GIF file, it is not Wilhite's (pronounced Jones) place to redefine pronunciation. His Jif-pronunciation messes with the efficiency of the acronym.

On article Canon launches PowerShot SX40 HS 35x CMOS superzoom (160 comments in total)

What is the actuation lifespan of this camera?

If anyone knows, please post this somewhere under a simple findable heading, e.g. "Actuation Benchmark SX40".
I'm referring to the sensor corrupting, and they do corrupt and the repair cost might outweigh the second-hand market value.

I'm still smarting from my Canon SX-10, for which I bought the lensmate attachment, the filter adaptor, extra lenses to fit onto the filter adaptor, multiple sets of batteries, dedicated camera bag and other extras, all worthless when the sensor corrupted after the 1 year warranty expired.

Lupti: 1080p24? The old SX1 IS had 1080p30. Geez, shove 24p up your ar*e, Canon. FZ150 offers 50/60p and you come up with 24p? Fail.

Agreed.

SX 1 - what happened to that angle - did Canon find it to good for the competitors and decided to wait for a more developed market?

SX 20 also has 12 MP, and takes penlight batteries.

It seems Canon brings out a good model and then releases micro changes to suit the market demand. E.g. Canon G10 - then G11 and G12, talk about going backwards.
Real competition is needed. Let's hope Sony can offer it.

How many actuations before the sensor is corrupted? Higher sensor sensitivity increases the risk. The first manufacturer that offers a benchmark guarantee, e.g 20 000 actuations within a 36 month perion, wins my loyalty.
