ogl: The external design dates all the way back to the Pentax Optio WG-2, which I believe came out in 2012

Is that nessesarily bad?

Link | Posted on May 29, 2017 at 03:49 UTC

I have owned a Pentax branded WG3 for a number of years now that I originally bought for cycling and sailing. It has been dropped, kicked, fallen overboard and even handled by children and never had a problem. I have been brave enough to take it to the crushing depths of 10 feet in my local swimming pool and gotten decent photos. I would recommend a good float strap to be purchased with this camera for anyone who lives where it rains as it does sink like a rock. A charging kit and an extra battery are a good idea too. My only two gripes camera are that it is difficult to press the shutter release with a gloved hand and that there is no RAW capture. Other than that I would definitely buy another one.

cshyde: It's weird looking.

A dog bone carved out of anthracite (with pieces of a rain slicker glued on in some models) for sure but incredibly easy to grip.

Craigski: Not one prime lens was chosen, or even mentioned.

Not to take anything away from the impressive achievements of the world's best optical engineers and manufacturers. I just bought a 50mm 1.8 STM lens and am relearning what it means to be an engaged photographer; moving closer or farther to obtain the ideal framing and composition rather than standing off, detached from your subject. What used to be the "standard" lens with every 35mm SLR still holds it's own against the latest high end zooms.

On article Leica SL Review (1093 comments in total)

Three years from now on DP: 3-1-2020, LUMIX announces it's first full frame camera. Although it's clearly a rebadged Leica 24 SL, it's $2200 price is less than ⅓ that of the Leica's. Sloth like auto focus and confusing menus have been greatly improved over it's progenator.

On article Canon patent shows curved sensor design (105 comments in total)
In reply to:

AstroStan: This has prompted me to ponder the physics of vignette. It is possible to mathematically model the lens and imaging plane or semi-sphere then compare that to real-world results (e.g. "flat field" frame). There are 4 primary components of photon-flux per area attenuation:

1) aperture transmission. This varies geometrically with angle of incidence. e.g. circular at perpendicular and a decreasing area ellipse with increasing angle of incidence,

2) geometrical distortions of the lens. Pincushion or barrel, etc. distortions change the flux per area (measured at the plane or semi-sphere).

3) geometry of the focal plane / semi-sphere / bent-plane (etc.).

4) pixel angular attenuation due to cicuit structures and/or micro lenses.

Issues 1-3 are not a simple calculation but the basic geometry is not that difficult. Issue 4 cannot be predicted without insider knowledge. But it can be measured indirectly by solving 1-3 and comparing to flat-image.

I may give it a go. Anyone else?

Stan

Didn't Leica address this problem a number of years ago? As I recall the problem was that the lenses designed for the rangefinder cameras were particularly vulnerable at causing vignetting with digital sensors. This was due to the fact that lens was so close to the focal plane and the angle at which the light exited the rear element at the edges caused fall off. Film didn't have this problem.

This camera would almost be useful with a fast, high quality zoom. Perhaps a 40~120
F 2.8 would be nice. It would likely cost around $3,000 and weigh more than twice that of the camera.

Roland Karlsson: Hand made in Sweden?

What would it made of or called if it were made in the UK? Or does it matter because it would most likely fall apart and be worthless after a few years.

So true! Like all fantasies and dreams, the wake up reality is never what one imagines could happen. I'd rather not have the facts get in the way of a good story.

jaygeephoto: Does anyone here understand the difference between high end professional equipment meant to do the heavy lifting and all the other stuff? It's not all about speed and megapixel counts or any of that; it's like comparing sports cars to trucks. If there was a story here about a Sinar or Linfof half the people here would be deriding them for not having neck strap lugs or a built in flash.

Cinematographers and photographers like the film look and "feel". I do sometimes miss shooting with my old 500C loaded with Ilford Pan-F; the results were sublime.

You make some excellent points. I'm not so sure that mirror/slap.camera vibration matter all that much to fashion photographers or product photographers working with high speed professional strobe equipment . Or even the landscape photographer that is on a tripod with a cable release and the mirror locked up. Other than sports or nature photography I'm old fashioned; I like turning the focus barrel myself. Film vs digital is a whole other debate however. Film has found it's niche as a fine art medium just the same as artist's brushes and paints. Filmmakers seem to still prefer it though.

In reply to:

obsolescence: Make the body text light gray ("silver") against the black background instead of white. That's all I think is needed to make reading easier.

Try and strike a balance. There's a reason that the gauges on your dashboard are light gray or white against black; it's easier on the eyes.

As soon as Nikon announced their D5 I know that we'd hear something from Canon any minute. My 1Ds's have held up remarkably well under regular use. I'm torn though between buying a 5DS-R for studio use and a 5D for field /PR use or just go with the sturdier 1Ds for both. Anyone have any thoughts on this?

villagranvicent: If Leica really want to honor the Panda and show its "profound interpretation of environmental protection" they should donate some of the profits to Chengdu and the people who take care of those bears. Other than that is simply marketing BS.

Supposedly when Porsche named one of it's models the Cayman, they pledged some portion of profits to preserve the Caiman. This is not confirmed.

Actually there was a mythical digital Nikonos. Whether or not this thing actually existed or it's some clever CGI is a matter of debate. You can be the judge.
Yes, many of us would love a truly professional type ruggediized DSLR or high end mirrorless that we don't plan on taking down to nuclear submarine crushing depths. I think the main impediment to the existence of such a camera are market forces.

I broke into a cold sweat just reading the headline; I would pack away my M cameras with fresh desiccant when there was even the prediction of rain!
Yes ad another 40 to 50 percent in price for anything EU produced and expect less performance, coupled with poor reliability compared to Asian counterparts. That's the way it goes.
But, then again Nikon never had the intestinal fortitude or the spheres to produce a digital Nikonos (always sounded like a mythical Greek island) . So hats off to Leica or Panasonic, or whoever they are. I'm going to to re-certify my SCUBA in any case.

Never a good sign when you have to sell such plans. There is no product sole in the entire universe that has a higher profit margin than insurance.

scottcraig: Whatever happened to the good old days when your tripod was bulky enough to be used as a weapon to defend yourself is someone ever tried to steal your camera. :)

. I have some Gitzo's like that. Carbon fiber one's are looking ever more attractive as I get older. Airline security once thought my 25 year old cast-aluminum body mono-pod was a truncheon. Oh well. My long standing philosophy on tripods is that there is good, light and cheap - pick two. But these are so adorable! Good match for a diminutive mirrorless camera.
