and that those sensors would be maybe ?? superccd sensors ???

No idea about Nikon cameras (though I'd imagine it'd be the same as sony since they make Nikon's sensors) but Sony's 12mp CMOS a700 has undeniably better ISO performance then the 10mp CCD a200/a300 sensor.

absolutely just like i said and you are repeating now different approaches in sensor making have different results. they have their benefits and short comings.

just like you said a CMOS might give better high iso performance (not always true tho) then CCD sensors of sony. and also a normal CCD will have worse high iso performance then superCCD (which is fuji films sensor type). these are different approaches which has their benefits and shortcomings. like having color artifacts with superCCD, or having great saturation with regular CCD sensors or having great high iso performance with CMOS etc etc. given the same sensors. like, take a CCD sensor from sony. bump it up from 6 to 14mpixel it will start struggiling with artifacts like luminance noise. solution instead of making a700 with the same ccd sensor as a200 use cmos. OR if you want better performance bump the sensor size to full frame. same goes for canon cameras. and sigma cameras and fuji cameras.

if that wasn't true, "like just bumping the megapixel was enough" there would absolutely be no need for full frame sensors. and canon or sony or nikon wouldnt bother but just improve their existing sensor and pack more photosites


anyway. bigger photosites in most cases (with exception of superccd's untill they reach aps-c size) give better iso performance so megapixels wont hugely improve iso or per pixel detail and in lots of cases and will make things even a little worse.

I just got a D90 and its a pretty solid Camera, Like the Sony it also uses a CMOS type sensor and not a CCD. Picture quality is awesome. Im using a 8G Sandisk Ultra Extreme III card in it and the speed is insane.

Most of them are too centered with no real focal point. Sure they're pretty, but nothing really stunning or eye catching (on most of them).

Many of them are also poorly lit, you could benefit from a flash for some fill. There are some that are overly soft, probably need to work on your longer lens technique (higher SS, holding steady, ect). Lastly you need to watch your horizons and keep them level. Lightroom makes it so easy to straighten a picture there isn't any excuse for having a plef'd image.

That being said, they do show promise and you've got a pretty decent eye, keep at it.

Thanks for the comment. By the look of it you really sound like a proffessional photographer with many experienced years... Could you please show me the work you've done so I could compare to a real photographer?

Not a professional, just know what I like. I've only been into photography for a little wile, but I'd got some decent shots. Unfortunately most of my good work in in Glamor/Nude photography, so I can't post that here... [rofl]

Here's a pic I like though, playing with my 85mm at the last hockey game I shot.



Lizard I like, but is way too centered, and I need to tweak the colors.



Like I said, no pro, but I know what I like.

And there's the build in VR motor in the camera body. Since I doesn't have any in my D40 I have to buy all my Zoom lens with build-in VR in it which cost more...

but now I explain that my camera is only 6mp, doesn't have the VR motor in it and the ISO performance could be better on the D90 etc..[surrender]

Hi, I looked through your photos and you have some nice pictures. I just wanted to point out that the D90 does not have VR (vibration reduction) built into the body. It has a built-in focus drive motor. The D40 does not have that. So, the D40 cant auto-focus with older lenses and some of the newer lenses (the lenses need a built-in focus drive motor for the D40 to AF). The only dslr body's that have built in VR or IS (Image stabilization) are Olympus, Sony and, Pentax. For all other manufacturers if you want VR or IS you have to get it in the lens.

As for the 6mp vs 12mp, do you print? If you print large (16"x20" or larger) you will need more then 6mp. If you dont print large are dont print at all then, more mp is pointless.

Yes you're right I though it was the VR but it was the Auto-Focus motor which lack inside my D40... That's also why I was thinking to upgrade to D90. I'd like to have the Sigma 150-500mm but I think it doesn't have the Auto-Focus motor in the lens so with my D40 I'll be stuck with manual focus mode which is kind of a letdown...

I do not print my pics however sometime when I crop them I have the feeling that I'm limited with my 6mp. I'd like to see the difference between 6 & 12. Anyway there's always a good excuse to have the greatest and lastest equipment [rofl] Sadly it won't be for now...

Not 100% true. The D90 will handle noise at higher ISO's better, and the increase in resolution helps retain more detail at those higher ISO's.

I agree that the D90 is better at higher iso's but, its not by much. At least not enough to upgrade just for that, unless you do a lot of low light photography.

Getting the D90 so you can use lenses that the d40 can use (cant AF with) is a good reason to upgrade. I always tell people to upgrade your lenses first then the body but, that wont work if the lens you want doesnt work with the body. Suck too, the d40 is a darn fine camera. As for cropping, you could always download a sample pic from the D90 and crop the hell out of it to see whats its like cropping a 12mp photo.

what ppl need to understand is, there is a diminishing improvement as you bump up the megapixel count. the improvement in iso performance is most often thru the software, and slight improvements on the sensor design, but that doesn't go parallel with the megapixel improvement.

think of it like a speaker.. more u wanna hear, more you bump the volume up.. but you get to a point where speakers aren't big enough (assuming u have a big enough amp). bumping up the volume will add nothing but more distortion (consider buzzing and distortion as the noise on your photos). u can come up with smarter box designs etc. even tho they will provide some improvement the real solution is bumping up the physical size of your speaker and going with something that can handle more power.

well i hope that example made sense ..

I think this is a bad analogy....

sensor technologies will keep advancing as they do now, and of course software has something to do with noise control and reduction, but that aside, noise generation can be reduced not only by software but also by making more effective sensors(photosites).

Some great pictures!

Damn it makes me want to get a dslr.

[Suvuseh]

Finally!


Yesterday I bought the D90! Terrific camera! Along with the MB-D80 Grip and 8GB SD card. I took some pictures with it. Here's the first one:

D90 - 18mm - f/6 - 1/180secs - ISO 200

very nice camera and nice pic good exposure.

congratz enjoy ur new camera

Ok I've updated my flick page once again with a couple of pics from another Zoo.

Much better! Like the DOF, composition, and subject. Might try bumping the green a little bit and messing with the WB to get it to pop.

Do a comparison,of the same exact thing with each camera body. Use the same lens, exposures, and camera settings on both the D90 and the D40, takes pictures and show us which gives the better pictures.
THAT's you homework for this weekend! [thumbup]
It seems you have the sweet lenses. So compare the quality of the bodie's abilities for us. please?

[9uWzBx4l]

Hmm that's a big homework isn't it? [xmasbiggrin] however I'll sure do it if I have the time this weekend! I'm still trying to figure out some of the settings and options on the D90. As for now, even if I didn't played around alot with it. At this early stage I can clearly see a difference between 6mp & 12mp. especially when cropping... I also think the bracketing is a very usefull feature when I'm not quite sure about the exposion and I don't have the time messing around with settings (especially with animals). 4.5FPS versus 2.5 for the D40 in continuous shooting mode does also make a difference with moving subjects. Status LCD & Autofocus... I know there's much more feature on the D90. But theses are the ones I particually like so far...

hehehe GRATS On the new stuff. That's awesome stuff!
I'm quirky, i love comparing the lower dollar stuff, to the high dollar stuff.
