On Fast and full-frame: Nikon announces 24MP Nikon D750 article (406 comments in total)

I am so confused by Nikon's naming convention. Is the D750 better than the D700? Is the D610 better than the D600 and the D750? What about the D7100? Is that lower than the D810?

Everyone wants to look like a Pro photographer but less and less people are willing to pay enough for it.

This is probably a great Full frame camera. Too bad the market for people looking to buy a new full frame camera is shrinking.

"offering a faster frame-rate than any non-professional full-frame Nikon DSLR since the D700". That is a ton of caveats in that sentence. What they should have said is "Offers half the burst speed of most smaller sensor cameras".

Everyone believes SanDisk cards are the most reliable only because they say they are more reliable. I have 10 SD cards of various brands. Only the Crappy Eye-Fi cards have ever failed.

The Eye-Fi cards are very flimsy around the contact points so I expect them to fail. None of the other cards fail.

Show me evidence that PNY is less reliable.

This card has a much higher GB per $ cost than the memory in the Microsoft Surface and I thought that was expensive. Still nowhere near how much Apple charges for extra memory in the iPhone though.

mpgxsvcd: “but you need to remember that ISO100 on a small sensor won't be the same quality as ISO 100 on a larger sensor.”

It almost sounds like you are saying “If I take a full frame sensor and cut it down to micro four thirds size the noise for ISO 100 will magically change”. If you crop a sensor noise does not change.

"Are you saying that cropping out the middle 25% of a photo has no effect on the quality of the photo?"

No I am saying it only affects resolution. The pixels are the exact same in the cropped sensor as they are in the full sensor. There is just simply less of them. The image view will be compressed into a smaller area but the noise will be identical to what was there before.

Please capitalize B if you are referring to bytes and not bits. 30 mb/s != 30 MB/s.

Sorry. I was typing too fast. I will try to correct that.

I fill the card with large movie files. Then I stick it in my computers SD reader slot. I cut the files from the card onto my internal 7200 RPM hard drive to test read speed. Then I write them back to the card to test write speed.
Ironically my UHS-3 card has had write failures when writing at 100 megabits per second on my GH4. Apparently the bit rate can spike above 100 mb/sec in the camera and it happened to spike when the card hit its min level.

Even the 30 MB/sec guarantee is not a guarantee that you won’t have issues. It is a statement they make to convince you that their product is better than someone else’s even if it isn’t.

I couldn’t get my PNY to write at speed less than 42 MB/sec. I tested it in heat, cold, humid, dry, and all sorts of other situations. It wouldn’t write less than that speed.

"The noise does not change, but rather how you view it changes"

Wait, are you saying that using a smaller sensor changes my eye? Now I am really not understanding you.

he image that the cropped sensor takes will be identical to the full sensor in every aspect except for resolution if you keep all other aspects the same and use an “equivalent” lens instead of the full sensor lens.

It is a myth that Sandisk cards never fail. They are just as susceptible to failure as any other card. Do you know what the leading cause of failures for SD cards is? It is damage due to handling. Being stepped on or being run over by a chair are great examples of handling issues. All cards are equally susceptible to those issues.

“But that is only 10 MB/s minimum write, this Sandisk is UHS-I Class 3 (U3) is 30 MB/s minimum write.”

That is absolutely incorrect. The spec only specifies that it will maintain speeds above that level. However, the card itself will maintain much higher speeds. The problem is that some cards came out before the spec yet they still achieve the same level of write speeds.

As Tommy Boy once said “If you want me to take a dump in a box and put a guarantee on it I will” but wouldn’t it just be better to buy a quality product that does the same thing for less money?
