On Fujifilm updates X-mount lens roadmap to end of 2015 article (141 comments in total)

There were rumors of an update to the 35mm and maybe the Macro as well? I hope these are true, but I doubt it.

I think this is probably now as solid a lineup at m4/3 which is impressive given the single company vs 2 that m4/3 has. I wish the 10-24 mm was smaller but it seems a good lens so far.

I will continue to save my pennies for an X-T1. The only real downside of that camera for me probably will be in cases of snow and sand where my eyes are super dilated which makes non-optical finders hard to see.

On Fujifilm announces XF 10-24mm F4 R OIS wideangle zoom article (172 comments in total)

This lens is heavier than the X-E1 so I hope the center of mass of the lens is toward the rear element otherwise things just become awkward. I have been waiting for this to be released and got a 14mm to tide me over to the release. This is the make or break lens for any system and myself. If it is terrible I will probably dump my X-E1 and lenses and put my eggs into my FF system (happy to dump the FF system if this lens rocks). I probably would need to get something like an X100s if this lens is horrible. Though I could stick with just the 14mm + other primes. I have my fingers crossed.

Needs a shadow area badly like the last scene had with the box at the lower left. Without that it is very hard to tell color shadow noise level.

Since Adobe stuff was the main thing holding me on windows, I guess this means I will just eventually switch to linux completely and use things like darktable.

Could have interesting knock on effects in cameras that are supported. Thankfully there are plenty of good choices in RAW processing outside ACR. I'll have to give capture one and DxO harder looks but if I have to lose an integrated workflow I will give competitors a big chance. Sad thing is if people worked together for a year we could have something better than photoshop with GPL free forever.

drwho9437: My camera is a mirrorless full frame camera similar to a EM5.

It however has a fully electronic pixel mask-able shutter. This allows all sorts of DOF reconstructions and high dynamic range methods to be employed.

To take a simple example, if you place it in HDR mode at 1/250 it will take 3 photos one at 1/1000, one at 1/250 and one at 1/60 in just over 1/60 of a second. This extends the DR of the image by 4 stops without blurring artifacts. Because the shutter is electronic there is no delay to cause blur between the images that would cause alignment issues. The data is integrated into a 3 channel RAW file.

Or equally the camera could sample at the shutter speed many times to integrate to saturation. This would eliminate well depth as a DR limitation on the sensors and provide true tone mappable images even into the darkest shows and brightest skies.

To be clear I am still describing a stills camera however it is possible that the focus (no pun) on video will integrate these features. Video even very HD is low resolution compared to stills, and I care much more about stills. Synthetic aperture cameras have been used in academic research. Completely electronic shuttering has existed in CCDs for a long time.

I believe we have significant room for improvement in spectroscopic data as well. Mimicking the human eye is one thing but the human eye is quite limited. I want a superhuman camera, which can render a subset of the collected data in a human looking way rather than bad looking HDR and other effects.

The ideal camera would let a photographer focus purely on composition and the critical moment, leaving complete flexibility in the technical aspects and processing.

I doubt we will see such a camera. Look at how many people care about JPEGs, dpreview included. JPEGs like MP3s shouldn't exist anymore. "Good enough" for the lazy.

mr moonlight: I know this is just the Beta version of the software, but wow! Image quality on the Xpro1 looks like it blows the other cameras out of the water at all ISO's

JPEG is okay but the RAW look quite bad, guess they haven't got the demosaicing down yet?

I hope this completely kills the DSLR video market, then maybe we can see feature sets that focus on improving stills rather than video.

On Canon acknowledges 'light leak' in the EOS 5D Mark III article (282 comments in total)

Pretty much a non-issue issue. Mostly because if you are shooting at something dark there isn't enough light to go into LCD to change the metering. You have to have something bright while shooting in the blackest possible conditions. In normal conditions this effect won't change the metering even 1/3 of a stop...

So it is a bit silly. The only time this would maybe be an issue is if you do use the backlight in the dark on a tripod to check the exposure I guess. In that case you might want to look through the finder to change the exposure or use the LCD quick menu...

I didn't know what PL was; presumably http://en.wikipedia.org/wiki/Arri_PL

EF -> Canon
F -> Nikon
MFT -> micro four thirds (Panasonic/Olympus).
E -> Sony

On Samsung US announces rugged and waterproof SD cards article (49 comments in total)

There is nothing inside an SD card that can be damaged by water as long as you don't power it on with it still wet and lots of ions in the water...

If you drop your card in the ocean you can simply take it home and put it in deionized water, and change that repeatedly until all the salt is gone. Then let it dry out. One way to help that is to use IPA to displace the water. Do that a bunch of times. Then let it sit.

Alcohols and high resistivity water is ubiquitously used in semiconductor processing.

The reply seems based on the proposition it is ethical to expect a business that lasts only 1/3 of the year to yield a yearly income. It isn't. If you wanted to make say 50K for photography on a full time yearly basis that would be fair. So the prices are about 100% to high by his own numbers it would seem.

In reply to:

drwho9437: My question is what is the widest angle lens the optical finder will support. That is how much of the frame are the 18 (28) mm lens' crop lines.

It is vital for me to have at least 20 mm in 35 mm terms on a system and if possible even wider. No doubt the LCD mode will support it but a large chunk of the appeal is the optical path.

Hopefully this can be either added to the preview or in the final review.

@ Glen I meant EVF/LCD I'm sure they support the same things. I don't mind EVF either but largely I have that with m4/3 already.

@ Andy Thanks. I noticed the 14mm note on the link page after the comment. Seems likely they would have designed the finder to work with that lens if it is almost in the first batch. Supporting this notion is the brochure which shows crop lines for the 18 mm not at the edge of the frame. It looks like 14 mm might just fit.

Like NEX, there aren't enough lenses yet. But I really hope this system is successful. More competition is always good.

In reply to:

Peiasdf: Wow, I didn't realize there are so many style over function people here. A poor man's Leica..... please shoot me if I ever choose style over functionality and buy a Leica or cheap knockoff.

I own a Nikon D90, an Olympus E-PL2 and I am thinking of replacing both with an E-P3 or NEX-5N/7 or their future equivalent. Neither system is perfect but they are a lot closer than the X to me and most people's need.

I am proud to say I will never try to impress people by telling them I spend more on camera than I actually spent. I will never glue a red dot on my cameras and pass them off as Leicas. I will not be impressed by a photo just because it was taken by a Leica nor will I respect a guy with a Leica but otherwise takes crappy photos.

Shame on all of you that want this camera because it looks like a Leica. Because it would satisfy your fetish with the red dot or put the X above other mirrorless because of the MSRP. All camera should only be judge by the function and picture produced.

Not everyone is a robot. If you didn't grow up on MF cameras from the 70s then maybe you just won't get it, but the experience of photography matters to some people.

Those dials and nobs aren't just for looks, it gives a different experience. The same one I get on my m4/3 camera with old glass that I don't get on my Canon system. The Canon is objectively better but it is so much less fun. If I did photography for a living maybe the Canon would be the only sane choice, but I don't. Buying a Fuji camera to look like you have a Leica isn't going to have a real snob appeal. Besides it looks vastly more like a Contax than a Leica. All rangefinders look something like this...

Or maybe some people just desire innovation over the MP war and stagnation of the SLR market... Maybe.

harold1968: looks like an amazing camera
however the one thing I don't like about it is the slavish rip-off of Leica
In someways I prefer the Nex-7 as it has a fresh approach

I think it looks a lot more like a Contax G2 than a Leica. Rangefinders look like this in general, who cares?

Tim F 101: Sad to say, this is one reason why I bought a GH2 over the EP3. I love my E-P1 but I have no idea what kind of warranty or repair support I can expect a year from now. I hope like heck that Oly makes it through this (and with different management), because their optical division truly does make excellent and innovative products.

That is pretty silly... But if enough people are silly it could hurt them. Having shot for 20 years and never had a camera repaired by the factory... Just buy a used one in a year if yours fails... Normally the deprecate rapidly.

On Olympus raided over accounting scandal article (83 comments in total)
In reply to:

James Wages: As well all very well know, Olympus does have some very competitive cameras in the mirrorless market. Panasonic would be well served to buy up this company on the cheap so they can learn how to make decent in-camera JPEGs. (As a GF-1 owner, I know how JPEGs suck raw eggs. In-camera JPEG may not be important for pro users, but my wife hates to shoot RAW, so having stunning Olympus-style in-camera JPEGs would have the net effect of making some of the photos that exit my Panasonic cameras look better.) If Panasonic doesn't do something, in light of the amazing NEX-7, SONY will capture the mirrorless market before we know it. I have bought heavily into the GF-1 / µ4/3 world, but having been a Minolta SLR film camera user a decade ago, the NEX-7 compels me to put those old lenses to good use. If this news spells death for Olympus, it will be interesting to see how things in the compact mirrorless market pan out over the next year.

The bulk of their business is not cameras. Buying a few firmware engineers out of the company is a lot cheaper than buying the whole company...

That 32Gb card costs almost $600 if you need a CF card rather than SD. The 128Gb CF card costs a whopping $2,000 here!!

Buy one off eBay? Someone will mail it to you first class from the US for a huge sum of 2 dollars I bet... It would be there in under a week.
