On article How the 50mm lens became 'Normal' (78 comments in total)

"a 50-mm best approximates human" *perspective*, not "sight". A picture taken with a 50mm lens (or equivalent, if not shooting 35mm) covers roughly the same area within your field of vision as an 8x10" sheet of paper, held at an outstretched hand. Or a smartphone screen at a reading distance. If a "normal" portrait is viewed at this distance, the nose-to-ears proportion is neither compressed (as in telephoto) nor stretched (as in wide angle).

kodakrome: Outdoors there are no walls to bounce off of. Suppose I want to shoot a duck by bouncing the flash off a different duck. Can I do that?

Leono: Some compact cameras have limited controls. For example, if I wanted to shoot the moon with an Olympus TG-1, the only way to force the exposure time to stay above 1/100 was to enable the flash. Without the flash, the moon would be completely washed out.

jhinkey: As long as it has 14stops of DR at base ISO and 40+MP then it will be great. Seems we'll be waiting a few years for that.

Placing a DAC into every pixel means DR is no longer limited by the capacity of the electron well, but by the bit count of the register that holds the result.

On article Hands-on with Panasonic Lumix DC-ZS200 / TZ200 (127 comments in total)
In reply to:

Julio Sánchez: I think is not a great improvement over TZ100. You gain extra zoom but you lost an extra f:stop.
Large zooms with a compact camera will be dificult to maintain steady by hand.
For the momento I don´t upgrade from my TZ100

2.8/3.3≈1.18. That's half a stop. A full stop slower than 2.8 would've been 4.0.

"Eco-friendly" mode, huh? My car has an "eco" button - to make the AC run at half-power, and make the acceleration lethargic at best. Which is, apparently, what it takes to approach the advertised gas mileage.
I wonder what an "eco-friendly"-mode does on a camera...

cpugourou: In France it is totally forbidden and heavily punished (5% of the turnover) for manufacturers to program the death of a product. Like for printers, washing machines etc.

Buy a ink printer in france and it last a decade. Buy one in usa and try to keep it running for a couple of years !

Apple is already under a huge pressure regarding taxes and a lawsuit by the goverment will be underway in january about this battery scandal.

My photo inkjet works just fine (a Canon, bought in 2011), except there's no driver support for it in Windows 10 (or Linux, for that matter). One of the reasons I've been keeping a Win 7 desktop next to it.

elee1967: One thing I like about TG-5 is that it can be USB charged. Not sure whether W300 is the same.

It wasn't just a USB connector. It carried an analog video feed too, so you could view pictures on a TV.

A waterproof camera really calls for wireless charging. Most of the diving/snorkeling destinations have wet climates. If you induction- charge and use Wi-Fi for file transfers, you can avoid opening the camera during the entire trip. That means no issues with condensation, and no sand on the seals.

Pentax had a rugged model with induction charging, but for whatever reason, nobody else followed suit. Which is unfortunate.

chrisby: Why are rugged cameras (Olympus, Nikon, Canon, Pana) still so crippled? There should be no problem to install a bigger sensor, at least 1/1,7 type; Tv, Av, P and M and perhaps a ND filter would lead to a great all weather camera. I use a Panasonic TS3 since years for extreme conditions, wating for a better successor, in particular for low light conditions. Whenever a new rugged camera is introduced, I look at the specification and think: oh no, everything remains the same.

Two reasons.

First, it's hard technically. Trying to fit a zoom lens into a narrow rigid box places a lot of constraints on the lens design. The modern 1" compacts get around this by using telescoping "collapsible" lenses, but those are impossible to waterproof.

Second, there's not enough money in the compact cameras market to drive the serious R&D that producing such a camera would require. *All* "tough cams" released over the last five years, were minor updates.

Shlomo Goldwasser: Time for at least a 1inch sensor?

The "tough cams" are one of the very few remaining categories of fixed-lens cameras that still sell in any numbers, primarily to the "active-lifestyle" users - skiers, climbers, kayakers, etc. A waterproof large-bodied fixed lens camera won't sell to the same category. Nobody will mass-produce a camera without a market.

Besides, what you're describing, can be easily achieved by an RX-100 in a waterproof case.

Shlomo Goldwasser: Time for at least a 1inch sensor?

The existing 1" digicams use collapsible lenses that expand an extra inch or two when the camera is turned on. Try to waterproof that lens, and it's no longer compact.

cosinaphile: love the idea of a tough camera .... why has no one in the many decades made one with at least the minimum "enthusiast sensor of 1 \1.7 or better a 2\3 like fuji x30
or Nokia phones of the past sized sensor ... also the lenses are merely good if at all never great lenses

genuinely wondering

There's another factor at play. In economic terms, the compact camera is on life support. Very few new models come out, most of them with very minor upgrades. The R&D money is gone. The TG series have been using the same lens for almost a decade.

Switching to a larger sensor would mean a complete redesign - and likely, a price increase. And the TG-5 is already near the top of what its target audience is willing to pay.

1" sensor and folded optical path don't mix. Large-sensor tough cams won't appear until either the flat optics come of age, or large sensors get enough resolution to implement a viable digital zoom with a fixed-FL lens.

To get 25-100mm-equivalent zoom with 3000x4000 pixels at the far end, they'd need a 12000x16000=192MP sensor. Not quite there yet.

"Tough cameras" follow a formula - a pocket-sized rectangular box of a camera, that offers optical zoom.

This is achieved by using a periscope-like optical design, also known as "folded optics". Which is a technical marvel - but also a compromise, that puts restrictions on the size of the sensor and limits the optical quality of the lens.

justmeMN: "freezeproof to -10°C/+14°F" -DPR

In Minnesota USA, that doesn't qualify as freezeproof. Not even close. :-)

> and since it’s sealed condensation issues are unlikely

With sealed cameras, you get condensation issues all the time. It's a common complaint. Moist, warm air enters the camera + camera body cools below the dew point = the lens fogs up.

The way to prevent it is store the camera overnight in a Ziploc baggie with an open battery door and a pack of desiccant next to it.

tinternaut: About time we had a Tough that comes either with a 1” sensor or even Four Thirds (e.g. a mean looking variant of the LX100). Ummm.. Yes, I think I’ve written the same here before now. That’s not to say the Tough 5 isn’t a fine camera - I just think Olympus is missing a trick.

Without a zoom lens, it will be another niche product. With a zoom, it will be much larger.

The many 1' compacts currently on the market, all have collapsible optics, that extend a couple inches outside the cameras body when the camera is turned on. Can't have that in a rugged cam.

"how do you imagine the third party manufacturers to connect the grip to the camera?"
Low-energy Bluetooth. Or Wi-Fi, or USB.
