On Nikon D5500 real-world samples article (129 comments in total)
In reply to:

Mssimo: Great camera, but where are the lenses? Nikon DX lens selection: 4 Primes, one f2.8 standard zoom and two wide zooms (all other are kit or super zoom lenses)

This segment will die next year. Full frames are almost hitting the magic $999 mark. Mirrorless have much better native lens selection and innovations.

Nikon has given up on DX, they are just "milking the cash cow till its bone dry" I would not invest in this system.

It's not the optics! It's the AF system in each camera body!

Not that the DPR staff doesn't have enough to do, but Real World Samples of the same scenes at the same ISO settings from the Nikon D7100 would make for an interesting comparison of the Toshiba/Sony sensors.

On Panasonic Lumix DMC-LX100 Review preview (950 comments in total)
In reply to:

Bram de Mooij: I own this camera for while now and I agree with almost all of the conclusions in this review. I do not care about the seperate flash, since I almost never use flash. I like the camera very much although at this moment I have no possibility other then rawtherapee to process raw files on a computer. I have noticed the distortion of uncorrected wide angle raw files is severe and am a bit surprised that this seem to have little effect on corner image quality or did I miss that ?
A viewfinder on a camera is essential to me (for that reason I do not like my GM1 as much as I expected). The quality of the LX100 viewfinder is not that great. As I wear glasses I keep on fiddling with that correction wheel. I do not seem to get that right. I will do some experimentation with the contrast and color settings of the VF now. Thanks for that advice.

Distortion is one of the five Seidel aberrations which has no impact on softness. Or hardness for that matter. Check your optics book.

I'm holding out until Hasselblad has a camera that delivers at least 750 Giga Bytes per picture:)

On Behind the Shot: Flames of the North article (68 comments in total)

Interesting article and great technique.

And as an easier way to produce these landscape photos focused from near to infinity, that's what view cameras and tilt and shift lens are all about. Scheimpflug imaging it's called.

Great idea but, personally, I find these examples missing the artistic potential of illustrating interesting connections in time and the same location, or connections in space at different times. The obvious use of layering is distracting.

But there's potential here for something interesting.

I can't find a new Galaxy S tablet at Verizon or Best Buy. What's the deal with Samsung announcing a product that's not in the market place?

In reply to:

ProfHankD: I think AA filters don't make sense anymore. Just have small enough sensels to be past Nyquist for any lens and do analog/digital reduction in resolution. Easy. As I account for Bayer filters, a 5um sensel is at Nyquist for a lens resolving 50lppmm -- which few do corner-to-corner. 5um is just 14MP APS-C, or 36MP FF -- i.e., the D800. A little higher sensel count just makes the AA issue disappear.

The D7100 pixels are 3.9 um. That's the major reason it doesn't suffer from lack of an AA filter.

I've had my D7100 for four months now and I'm liking more the more I use it. Really impressive image quality particularly compared to the D90.

I find Nokia's whitepaper on the Lumia 1020 to be pseudo-engineering without any math--a.k.a marketing hype--and only serves as the latest example of elucidation through obfuscation. It might serve to make the clueless feel they're purchasing some advanced technology, but really, how is Bayer sensor interpolation noise overcome by (electrically noisier) oversampling?

In reply to:

mosc: It's not unique to cameras or even tech gear. Flip through your TV infomercial section to see exercise equipment and programs, jewelry, collectibles, cleaning products/equipment, cooking aids, time shares, the list is never ending. It is deep seated cultural materialistic desires routed in our love of self indulgence.

People try to feel better about themselves by purchasing rewards. Our spending patterns show a pretty direct correlation between unhappiness and "impulsive" purchases. At the extreme, people compensate for problems in their personal lives by acquiring things they enjoy in small bursts of time. This is exasperated by marketing that plagues on addictive personality traits and looks only at the moment of sale as the only value add to the company. The purchase itself is the enjoyment, not the product use.

The only real way to break this cycle is to find things you find rewarding by interaction with others or by accomplishments rather than purchases. The problem is mental.

Boy isn't that the truth. I had to sell my Ferraris just to keep up with the latest in tube electronics.

dennishancock: Timely article and greatly appreciated!

One further question: what would be a recommended color temperature setting?

Thank you.

5260 K seemed to work out well.

GPW: Can the buffer be fixed with a firmware update?

On the face of it, this is a lack of memory hardware not correctable by software. Something like a car with a two gallon gas tank. Unless of course the RAM is there and Nikon has switched it off.

In reply to:

mforbes: You guys crack me up, complaining about the buffer, I make my living taking photos of outdoor adventure events, zip lining, white water rafting etc., I use Nikon gear and have no idea what the buffer size is in any of my cameras, we don't have time to spray and pray and have the guests sort through a bunch of images and pick out the ones they buy, we do that for them by getting one or two good photos of them. If you need a large buffer for Fido running around the backyard, get a V1.

Precisely.

There would be a wide spread of requirements on buffer size taking a picture burst. It would depend on your personal situation and desired outcome.

Apparently gymnastics photography places different demands on the photographer than photographing white water rafters.

oeriies: I've been using the D7100 for 3 weeks with a 500mm f/4G and a 35mm f/1.8G. I've been a Pentax user for a while, currently owning a K-5. There is a lot of detail in the D7100 shots, which is important for birds and wildlife, and the continuous autofocus system is a dream compared to the K-5. The bummer is the buffer, as others have noted and as is clear in the DPReview appraisal. I spent an hour shooting seagulls in flight the second day I had the camera just to try to learn my new gear. I knew from the specs that I should get 6fps shooting raw. Fired off a burst to catch an on-coming bird -- 5 shoots and the camera stopped dead. I thought that for sure I had a defective unit. It was only when I went to the user forum here that I found that this is how the camera is designed. Nikon, you've got to be kidding. I hope there is at least a partial fix via software for the buffer problem that we'll see soon. It is a crippling flaw in an otherwise excellent camera.

Nikon would do its customers right by recalling the D7100 and adding a larger image buffer.

On Just Posted: Nikon D7100 in-depth review article (401 comments in total)

I have recently migrated to the D7100 from the D90 and it's proving a quantum jump in image quality, noise, color rendition, focus response, and features.

What condemns the D7100 to the insanely good category as opposed to the insanely great in my mind is the issue heavily discussed here--the image buffer. I'm not a sports oriented photographer and I'm OK with jpegs, but the thought that skimping on two dollars worth of memory is Nikon technical management's idea of the pursuit of technical excellence is astounding.

I'm getting a burst of 18 jpegs before the frame rate drops by approximately two-thirds. ( DX mode, optimal compression quality, fine image quality, large image size.)

Considering this camera is otherwise a technical tour de force, it appears Nikon technical management wasn't thinking. Marketing should be asking how many sales of the D7100 it will be losing because of this gaffe. Heads should roll. I know they would in America.

P.S. Great review, DpReview!

Great article. Stunning results. Would be great to see these images in 3D.
