That somehow makes sense but also not... if you need to buy more cards then it get only more likely that one will fail because you've more.Personnaly I would rather have multiple 4GB SDHC cards each of which is filled by 100 to 130 DNG+JPG - that way I minimise the effect of failure of a particular card
Of course all failing at the same time is very unlikely.
I'm not so good in probability calculation, hopefully someone can enlighten us

Thank you all, one of my survived a the washing machine so it's hard to break them most failures would be electronic.
The score is very good, you can't say the cards are unreliable.

Do you think Pentax would/can make an update for those cards like they did for the *ist so that they work with SDHC?

Well 64GB cards are coming this summer, I can get 750 photos (PEF K10D) on 8GB so around 6000 would fit on the bigger card, I think storage wouldn't be a problem johnriley wrote:

Same here. I fear dropping or losing individual cards more than electronic failure, and of course while the card remains inside the camera you're unlikely to lose it (we all hope!)The only failure I have had was not electronic but the write protection switch falling off.

I was talking about around 1900, it must be so different to be a photographer those days.

I know they are very tough but many say you should back them up... I'm going on holiday for 10 days and I will probably just take two 8gb cards with me and look at the photos at home.
So what is the failure rate, I've 6 cards and none have failed *knocks on table*.
What is your experience?
Since amount of card varies I'll ask for an percentage.

Oh wow great luck you've there

John, didn't they use FOV to calculate what will be in the frame in the early days?
Aren't we just spoiled

Sorry but isn't purple fringing a form of chromatic aberration?
Also PF is depended on the sensor so results may vary by camera. http://toothwalker.org/optics/chromatic.html
I don't know how he meters his CA...

Of course you can get the same FOV on FF with the same lens by moving closer to the subject, but that's not what we were talking about in the discussion on FF. We were talking about the difference between sensor formats when all else is equal.
So your point is correct but irrelevant.
True but if only Focal Length and sensor size is important, then why not use AOV instead or is distance also important?Of course you can get the same FOV on FF with the same lens by moving closer to the subject, but that's not what we were talking about in the discussion on FF.

Dan then the DA*60-250 is a lot worst link so really it isn't that bad

Most here say the sigma is quite soft at the edges at 300mm, don't know how fast the fall of is though
