SD1400 to sd4000? Improved image quality?
Wondering if anyone has gone from sd1400 to sd4000? I'm not very impressed with IQ of sd1400 and am thinking sd4000 should be a lot better, anyone made this change and care to comment?
I haven't done that personally, but if you search for "imaging resource comparometer" you can see identical studio shots from each camera at different iso's which should give you an idea of the difference.
I have SD 4000, and just can say that I'm very satisfied with this camera. I only use the automatic mode, and 95% of photos are very great, even in environment with low light, the photos are good..
And the HD videos is amazing, and its size of the camera is very good too.
The SD1400, SD4000, S90/95, and G12 all have very similar image processing, with each one having a slightly sharper and more contrasty image (in that order). If you want to see a significant difference in image quality, you'll want to step up two or more models, not just one. The difference between the SD1400 and SD4000 image quality is fairly subtle, as is the difference between the SD4000 and S90/95, and likewise the S90/95 and the G12.
Then again, if you are looking to improve low-light shooting then the SD4000 is a significant improvement due to its faster lens.
fyi, Canon just announced the sd4000 replacement today -
I had SD410is (4MP) for several years and it finally broke. Bought SD4000 recently. Speaking strictly IQ, I cannot see on the monitor that SD4000 is better than my old one. Yes there are more megapixels and the picture can be expanded to a larger size, but when viewed on 18"-19" monitor (in monitor size), I am actually disappointed in picture quality when comparing to SD410. I think the old lens perhaps was better quality?
On the other hand, it obviously has more menu choices and it's video capabilities are far better.
While increasing the pixel resolution they've also added a lot of anti-noise processing, and the resulting artifacts are (ironically) much easier to see thanks to the increased output resolution When printed out, the higher resolution image will probably look better, in spite of the artifacts.
It's also possible that the lens is smaller and less contrasty. Ultimately a bit inferior, like you said. Regardless, you should see much better high-ISO performance out of the SD4000, partly due to the anti-noise processing, and partly due to the extra stop of light you can get with f/2.0.
I will play with the camera settings and put it through a rigorous test (lots of pictures in different environments) and see if I can up it's (DS4000) IQ performance. On the other hand, I now have more incentive to spend $500 on that DA 21mm for my Pentax K-7 (I have DA 70mm and it's fantastic).
