Actually Iam not limited to 1800 dpi, the scanner goes up to 4000 dpi. I was told however that for 13x18 there is no real need to let the dpi rise above 1800.
...
Edit: You were told wrong unless you're not talking about 13x18cm prints but 13x18". If you're talking about 13x18cm prints then 1800dpi is more than adequate... (But only if you're absolutely sure that you're not going to crop later!)
I think a large part also boils down if you are prepared to carry a tripod. In the past, with analog still reigning the world, people usually stuck to a just a few different ISO films (e.g. just 100 and 400 ISO) and only rarely went for the more exotic ones like 3200 ISO. This meant generally low grain, and after scanning a nice image, and you carried a tripod if you couldn't handle the longer exposure times. But even with higher ISO film, you should still get a clean (in terms of typical "digital" errors like color noise - these horrible red / green pixels in dark parts of the image), albeit grainy image...
Now, in the digital age, with cameras supposedly supporting ISO of 1600 - 25600 :rolleyes:, and cameras with Vibration Reduction, Anti-Shake or some other kind of gizmo, people think they no longer need a tripod... Just choose 6400 ISO and go!... Yeh, well, if you want a picture looking like a Scottish kilt
If you are prepared to carry a tripod, and stick to ISO 100-400 max, just like in the analog age, most digital cameras should give you both a low noise and good contrast image, go upwards to 6400 or so, and the image goes down the drain.
About the Sigma, I have had a Sigma 28-70 F2.8 EX lens with my analog Minolta Dynax 7 for years now, and have been very pleased with it. It's a good lens, and gives me nice, and sharp, images, especially when shot from tripod, with mirror lock-up before release. No complaints.
And if you want to see what a good professional scanner like an Imacon Flextight 949 can do with film, go here:

The new Canon and Nikon models have excellent high ISO performance, so to a certain extent high ISOs to eliminate the need for a tripod. Additionally IS and VR systems do work well.
My experience with Sigma lenses has not been so hot. I'll never purchase another.

Ditto. BTW, I recently purchased a Tamron 17-55 f/2.8, and it performs incredibly nice -> very sharp, nice contrast/color. Highly recommended! (For quality in a budget.)
Let's not forget the Sony line, especially A700 -> which has a new CMOS sensor which does "in-chip" NR. Plus, IS/VR is included with the camera (Steady Shot), therefore all the lenses you mount to an A700 become IS / VR (without the added premium as in other brands).

I think it's going to be a while before Sony can pose a big challenge to C&N pro and semi-pro line of DSLR. But competition is always good.
I don't think Sony's NR at high ISOs is as good as Nikon or Canon's rendering. There are examples on the web comparing the different renderings by C/N and Sony.
But about pro usage: it will take another 5-10 years, but in the end, after the maturation of a new generation of young photographers that right now start out with Sony bodies, it is likely Sony will become a real player in the pro market

Guys, what Sigma lenses did you have? One of those cheap Sigma ones like the 75-300 F5.6-6.7 or something? :confused:
...
I recently enlarged a 100TMax 35mm negative made with my 28-70 F2.8 EX lens to a size of about 11x16", the image is very sharp and convincing.
Here's one:Can you please provide me a link to NR rendering comparison between semi-pro C/N & Sony cameras? Thanks in advance!
Well, if you think so then maybe you should read this:

"...
The level of pixel peeping complaints and criticisms levelled at the Alpha 700, which has unrivaled colour fidelity and tonal rendering straight out of the camera at ISO 6400, is either sad or laughable, Im not sure which. This is a performance we could never have dreamed of when Konicacolor 3200 was the fastest colour film on the planet

"...
In practice, even Adobe ACR offers all the quality needed to make stunning and superbly colourful A2 size prints from ISO 6400 - as does the camera itself, with in-camera JPEGs displaying plenty of detail compared to even the best raw conversions.
..."
In advanced amateur / semi-pro league, it's not fair comparing cameras (especially in terms of noise, especially when we have nice tools such as NeatImage and NoiseNinja which can do noise reduction much better than in-camera algorithms) according to their JPEG performance...
Besides, I seldom shoot @ ISO sensitivities higher than 800, so I went for better performance/price compared to C&N...

Here's one:
http://www.cameralabs.com/reviews/Sony_Alpha_DSLR_A700/noise.shtml
From the review:
Ultimately the A700 delivers good performance across its sensitivity range, although it's clear the full-frame sensor of the Canon EOS 5D retains a comfortable edge at higher sensitivities.
You can Google for others.
I don't hesitate to shoot at 1600 with the 40D and 5D. I imagine the A700 will be close but not quite as good as the Canons and I'm sure not as good as the Nikon D300, D700, and D3.
Do you own an A700 or thinking of buying one. I'm not sold on the Sony system yet.

My current Tamron 17-50 F2.8 beats the Sigma and both the following Minolta full frame lenses: 24-105D and 100-300 APO D (which were giving me very convincing results when I were using them with my Dynax 7). It's said that it's on par with CZ SAL1680 in terms of resolution...

The Minolta/Sony system may not be strong enough to urge someone to convert from Canon or Nikon (especially when they have considerable lens / accessory investment built around one), but it's definitely a good system for those who start digital from scratch or were former analogue Minolta users (like me). Simply because: for the same money, they offer more.

(gave the former A100 to my fiance)
and I also don't hesitate shooting at ISO 1600.
.were former analogue Minolta users (like me). Simply because: for the same money, they offer more
Now I am thinking about two possibilities:
...
Now my question is simple, what will give me better images with reference to color/contract/sharpness and the like. Analogue + scanning or Digital
I dont buy the 28-70 f/2.8 Canon L (because I heard that this lens doesnt work very good together with digital camera's,
1) I buy a second hand EOS3 body like I used to have and a 28-70 f/2.8 Canon
2) I buy a second hand Eos 5D, with this I dont buy the 28-70 f/2.8 Canon L (because I heard that this lens doesnt work very good together with digital camera's, thats why they made the 24-70 f/2.8L)
