On Sony unveils FE PZ 28-135mm F4 G OSS cinema lens article (104 comments in total)
In reply to:

AlanG: Clearly Sony sees that one place to attack Canon and Nikon is in the full frame video market.

But there is a new market for people using mirrorless and live view DSLR cameras for video. I think Canon was initially pretty surprised by the popular adoption of the 5D Mark II by video users. While Canon has a head start, Sony surely sees this as a platform they can compete on as it is less dependent on legacy gear. (Canon and Nikon lenses work on the A7, manual focus is common, and there is a market for higher priced video lenses at prices that are still way below Hollywood level and other pro gear.)

On Ricoh surfs into action camera market with WG-M1 article (106 comments in total)
In reply to:

mgm2: "30 FPS is closer to what the brain interprets as "natural" over what 60 presents. The ideal number is actually around 40 (38-42 as most experts will say, it is a somewhat subjective number). That said, 60, and whatever number you want to come up with greater than 24, are not explicitly "wrong" however they create an unnatural motion." We may want this unnatural motion in our games but not in our rendition of everyday life.

I shoot from a quadcopter at 60fps so I can go to slow motion when I want.

On Zeiss introduces 'no distortion' Otus 1.4/85mm article (336 comments in total)
In reply to:

Frank_BR: Title of the article: "Zeiss introduces 'no distortion' Otus 1.4/85mm"
-------------------------------------------------------------------------------------
It is evident that the author of the article does not know the difference between "distortion" and "aberration". Distortion is when a lens bends the non-radial straight lines of the image. According to the Zeiss datasheet, the distortion of the Otus 1.4/85 is about 0.8% at the corners. In comparison, the distortion of the Nikkor AF-S 85mm f/1.4G is only 0.41%, and the distortion of Samyang 1.4/85 is 0.43%, as measured by Lenstip.com:

http://www.lenstip.com/264.6-Lens_review-Nikon_Nikkor_AF-S_85

Conclusion: The Zeiss Otus 1.4/85mm is far from being a 'no distortion' lens.

Yes but the Zeiss press release says this, "no color fringing or distortion, and an extremely high image contrast all the way into the edges."

In reply to:

AbrasiveReducer: How about a no distortion 20mm? Or a no distortion wide zoom.

That depends on what you are shooting with it. As an architectural photographer, I appreciate the lack of distortion in my Canon 17 and 24 tse lenses when shooting buildings. (Perfectly rectilinear)

But when I have people in the frame near the corners, barrel distortion can be beneficial and actually make people and other objects look less distorted. I like that distortion in the wide end of my 16-50 Nex lens. I can always remove the distortion digitally from those images however I sometimes add barrel distortion to "undistorted" images.

So there are two concepts of distortion at work - various types of curvature of field produced by the lens. And the so-called distortion of having a close perspective on a subject when using a wide rectilinear lens.

SAERIN: These firmware updates are like refried beans. They can't get on the first try.

The idea is to make the camera compatible with an upcoming standard... something that did not exist when the camera was released. I don't see why anyone would complain about a company adding features and keeping a camera current at no extra charge to existing users.

In reply to:

pixelatorcw: The news feed must be somewhat limited when a company's PLAN to issue a firmware update is considered top news...

In this case it adds features that may be important in the purchasing decisions of some buyers. This is no different than announcing that a new camera will be available in December. Many companies give details about upcoming offerings.

I am very disappointed they did not use the new advanced strap system from the T, so I won't even consider this. And no mention that they hand polished a solid casting on this camera for 45 minutes? So is the T made better?

Seriously, a new camera that uses the same old low res EVF when Leica has a new higher res EVF for the T. I guess that would require upgrading the basic internal electronics to something similar to the power of what Sony offers in $500 cameras.

Codik: Wow, the hatred. I love my M240. It's an amazingly pleasurable to use picture machine. It's also small, light, and discrete.

"There are many people who think if someone has something nice (a car, house, boat, job, etc.) it's because that person somehow cheated others. They can't believe you just worked hard and earned it on your own merits."

Is that what you think this is about? I probably made $30,000+ this year on an investment in GT Technologies... the premier company for saphire glass screens.

That doesn't mean I think it is reasonable for Leica to charge $1000 more for a saphire screen and a bit of RAM. But if the MP buyers have no problem with it, why should I care? However on a price vs. features, usefulness, and performance basis, this camera looks very unfavorable to me.

On Leica T (Typ 701) First Impressions Review preview (2300 comments in total)
In reply to:

NCB: OK, you go out and snap away with the T just as you might with say a Sony CSC, and it's not the same. DPReview didn't like the Nikon Df either, for much the same reasons. I have the Df. It's a dream of a camera and I wouldn't be parted from it.

Not all of us go around with our digicam glued to the eye and snapping at everything which moves. For a start, you miss a lot of good scenes that way. Some of us take our time. I see a scene which has got something and mentally frame the possibilities before ever I get the camera out. I turn it on and twiddle the odd setting, if necessary, before it gets to the eye. There's nothing in the operation of the T which you've run through which would put me off. In the slightest.

I want sharp pics with the right colour and exposure. The JPGs might be a tad flat; seeing what alternative settings could do would be useful. But the colours are superbly natural. The T has distinct attractions.

Expensive? Not for a Leica. Or other options for that matter.

I don't see why you can't use any camera as slowly and methodically as you would want. But if the camera won't work as quickly as you need, you are out of luck.

In reply to:

The Customer: I've already read enough about the camera, on line, to know that if I could afford one, it would almost certainly be my daily shooter. Beautiful!

Exquisite lines and, from the footage I've seen about its creation, craftsmanship! I especially like the colourful body skins -- very stylish and high-tech while still conveying a playful air! I think that's what appeals to me the most about this camera, the feeling that it's been designed for people who want to fit precision, performance, and Leica's rich tradition in their pockets, while still being able to have fun. It's a camera that says, "Hello friend, let's play!"

Those colorful skins may not have been so well thought through. This comment is copied from a Leica forum....

Looks are indeed great but what a disappointment in use. It not only is very hard to put on or to remove, but you have to do this every time to acces the SD card or USB port or to replace the battery. On top of that I did not figure out yet how to remove or put on the T snap without detaching the strap (left side)

So every time you need to charge the battery you need to do the following :
- search for the "pin" to detach the strap (where do you guys put the pin so that it is always with you and does not get lost )
- detach the strap left side
- detach the lens
- try to remove the T-snap (good luck to do that in less than half a minute)
- put the lens on or a body cap to prevent dust on the sensor while charging
- remove, recharge battery and replace
- detach lens again or body cap
- put the T snap back on
- attach the strap left side
- mount the lens

AlanG: I bet photos made of the region by RIT photo students over the decades would probably encompass an interesting documentary collection.

Also keep in mind how many serious amateur photographers lived in Rochester all of those years. Including former Kodak employees. They must have documented the heck out of that city and facility.

rowlandw: I spent some time in Rochester around 2000 and perceived it as a good value proposition to move to (from Boston) but stayed put. Sorry it's on hard times and hope it doesn't become a little Detroit. I hope RIT (great school) can help buoy the city's fortunes. BTW I'm in Maine now which IS a good value proposition!

I attended RIT from 70-74. Keep in mind that RIT is in South Henrietta and not really in Rochester. So if anything, it draws people and businesses away from the city. I believe the University of Rochester is the area's largest employer.

Yes, as mentioned, having a curved sensor will simplify lens design in general. Lenses can be designed for a specific curve and still have a lot of imaging advantages even if the ideal solution would be a different curve for each lens. (I guess someday a curved sensor could be built into each lens on an interchangeable camera as Ricoh did.)

Btw my guess is these are concave sensors not a curve in one direction on an otherwise flat sensor. But I'm not sure.

Markol: I sometimes see people using tablets for taking photos, so I guess that's the connection to this article being posted on the dpr site. Otherwise I would think that it's slowly turning into a tech-blog.

Well this can be a photo accessory. I use DSLR Controller software to connect my Samsung Galaxy phone to my 5DIII for tethered shooting. You connect them with a USB cord and the software starts up instantly on the phone. I could see using a larger tablet for this also.

Also, a lot of photographers use a tablet for a portfolio.

On Panasonic FZ1000: Not just another superzoom... article (158 comments in total)
In reply to:

W5JCK: Bridge cameras like this one and the RX10 or still what I consider to be sub-enthusiast level. The 1" sensor is too small to deliver quality IQ at any low light level. That f/2.8 lens on a 1" sensor is equivalent to a f/5.0 lens on an APC-S camera. Pretty darn slow for wide open, and thus rather lacking in low light capability. A f/4.0 lens on a 1" sensor is equivalent to a f/7.1 lens on an APC-S camera. So this camera basically has a f/4--f/7.1 zoom lens compared to APS-C DSLRs and mirrorless cameras. Meh! For the price of the RX10 you would be better off with a a6000 and a few good lenses. This one is cheaper, but still not worth the price for anyone who wants an enthusiasts level and above IQ. This is a mom/dad camera used to take little pictures to post on the internet. Again, meh!

"This 1" sensor camera. Anyone who thinks this little sensor camera can be set to f/2.8 and duplicate the photo exposure, low noise, an IQ of FF or even a APS-C using the same settings is quite delusional and extremely confused."

Yes but that is only one way to look at it.

The smaller lens and sensor will give much more depth of field at f2.8, so if that is what you are looking for, it may be a solution.

I found similar improvement in gaining more depth of field by moving from 4x5 to 6x9cm. I ended up needing f16 on some interior shots instead of f22 due to the shorter lens. This meant needing half the number of flash units or fewer multiple pops.

Now I am shooting on FF 35mm instead of 6x9 and may only need f8 with a 24mm lens. Thus I can use much lighter strobes.

If you go to a 1 inch sensor with 9mm lens & can use f2.8 and get enough DOF for a group photo, or interior for instance, it will be possible to use much weaker supplementary lighting at a given ISO.
