It would be stupid to go for it, with PMA being next week. Just hold off till next week. You know you should wait, or else you wouldn’t have even asked us, if you should wait. You are trying to balance your impulse of buying a brand new cam now vs doing the resposible thing of waiting till next week. I’d say wait, and see if D5000 will come out and if so, what specs it will have.

You go for it, nothing in new Nikon range will have electronic shutter that allows 1/500 flash sync.

You should buy the touchscreen part, it is almost inevitable!

The reason i asked the question above is because I am contemplating on buying a D40 and thinking whether it is worth waiting until PMA or go for it now (I use a D300 now and I want the D40 just for its 1/500 flash sync, and it is cute and small!)

Do you guys in NR think that once D5000 (if it is for real), the price of D40 with the 18-55 kit lens will go down until the D5000 is available in the market??

plus what makes you think a 24mp dx sensor is harder to make than a Fx sensor. We have 15mp point and shoot cameras. That would have to amount to much higher pixel density than a 24mp dx sensor.

basic principals are just we we believe to be possible. Nikon keeps suprising us every day. Your comment was saying that noise would be to high for a 24mp dx sensor, and as I said you have never used one. So stop making statements you can not back up

Yes, we are all allowed to have an opinion. However, your opinion as you call it, was stated as a fact.

markdphotoguy, where did you get the stitching idea from? Maybe I misunderstood you. I always thought (and still do) that sensors were cut out in one piece from a silicon wafer which itself is circular. No stitching necessary

Then there are two reasons why larger sensors are much more expensive than smaller sensors:
1. The area is larger, so the chance to find a fault is proportionally larger. Let’s say the FX is twice as large as the DX sensor, then Sony/Nikon would also need to trash twice as many FX in production compared to DX sensors.

2. With the silicon wafer being circular and the sensors rectangular, you will always have some waste silicon simply because you cannot cover the circle with rectangles. Now, if you cut out many small sensors from the wafer, the total area of these sensors will be larger than the total area of large sensors cut out from the same wafer. Just imagine arranging many tiny rectangles on a circular ara, you will almost cover the whole area. If you used large rectangles there will be large areas close to the periphery which you cannot cover.

Both factors will cause the price ratio of DX and FX sensors to be more than the ratio of the sensors’ areas.

Really? You miss a 12mm DX lens that existed in the film days? Fascinating…

Forgot about the no AF on the D40, oops! I use it on the D200 & 300 so forgot about that!!!

It is actually allowed to have an opinion ?
or are your opinions final

TO PRODUCE A 24 MEGAPIXEL SENSOR FOR DXS FORMAT IS MORE DIFFICULT THAN FOR FX FORMAT …DO I REALLY NEED TO EXPLAIN BASIC PRINCIPLES TO YOU ?

By: David Olsen

I used one today , yesterday and I hope tomorow .
Unless you can prove D3X does not use nikon sensor ?

The old AF 50 f1:1.8 D is great, it was the first lens I had on my D40. I can’t understand the complaints about it… It worked well for me! Besides this one tiny little baby hick-up: no AF. If you shoot in a studio or have a professional model and plenty of time it’s great. Moving objects are well beyond my capabilities though

I am also a D700 user and waiting with fingers crossed for a replacement for the 70 200VR as I tried two and both were razor sharp in the centre but soft at both sides and the corners for close stuff even stopped down The vignetting doesent worry me I can fix that but the soft edges and corners are just not good enough. Or an updated 70 400VR…

Not to mention that DX also offers the versatility of more compact lenses such as the 18-200mm. Personally, as a D3 user I am looking forward to a “D5000″ if its specs are similar to the rumour. I really want a Small Body camera to take on Family Day Trips. The D40 was perfect though I would love higher ISO capability, better Colour Gamut and the improved active-D lighting.

Really hope the D5000 keeps the 1/500 flash sync but given the fact the D40x dropped it, I think it is unlikely.

Where is there even a 24mp APS-C sensor to be purchased? Samsung, Sony, Kodak, Fuji do not have an APS-C sized sensor with that resolution.
