Digital ISO sensitivity When I am looking at Nikon's and Canon's digital SLR camera, I see that most Nikon DSLR have ISO starting from 200. But Canon is having ISO 100. I would like to know is the ISO sensitivity the same as film in digit. I am taking film so far. I perfer to use ISO 100 or less since they are fine grain. Is the ISO sensitivity meaning difference in digit SLR? I am considering Nikon DSLR since I am using Nikon film camera. Will the quality of an image of ISO 200 in Nikon be as good as an image of ISO 100 in Canon if(let say)the resolution of both DSLR are the same? Should I take ISO into account when buying a DSLR?

Yes, the digital ISO is very very close if not exactly the same as film ISO. I hesitate to say exactly because chemicals and the emulsion is such a different process than how sensitive a sensor is to light. They're pretty close though. Just thinking about the reputation that Nikon has, I'm sure that the quality as ISO 200 isn't going to really make that big of a difference. Especially if you're looking at buying a newer Nikon DSLR. I've got a quick idea for an experiment. If you don't already have one, buy a cheap 128MB Compact Flash card and take it into a camera shop. Ask permission first...but take some pictures on both the Nikon and Canon that you're thinking of buying or that you're partial to, take it home, and see if you can deal with the slightly extra noise. Make sure to take a picture of something that has one main color since photo shops tend to overwhelm my senses when I look through a camera in them. Use the 200 ISO setting on both of them and the ISO 100 on the one that will allow. Hope this helps you out!

Hi Ella! The New D50 From Nikon Is min 100iso The D1X Is Min 125iso The D2X Is Min 100iso Not Sure Where You Got That Info? The D70,D100 And D2h's Are Min 200iso So Nikon Does Offer Different Options.The Difference Between iso100 And 200 Isnt Much The Two Camera Makers Use Different Type Imaging Sensors,Comparisions Can Be Checked Out At This Link; http://www.dpreview.com/ Research Before You Buy:-)

Hi Ella, I don't think you woud find much difference between ISO 100 and 200. I think a more important consideration is do you use a Canon or Nikon film SLR now? If so and you have invested in lens, it makes sense to stick with that brand because Nikon and Canon both make excellent equipment. Hope this helps. Regards, Del

Hi Andrew, Terry and Derek, Thank you for all your advise. I think I can go to the camera store and try to take a few pictures for comparison. I know dpreview has detail analysis. I am actually waiting for Nikon to have a model that's close to Canon's 20D for comparison... I am waiting for Nikon because I am using Nikon and as Derek said I can reuse my lens. However, I don't know when Nikon will release the new camera that I am waiting for. I really want to buy one as soon as possible to take more pictures and improve my skill. Another concern I have is the sensor. D50, D70, D70s and D100 are using CCD. Canon's 20D and even the new 350D Rebel XT are using CMOS sensor. I know that their technologies are different. Nikon's CCD may be as good as Canon's CMOS sensor. My understanding is that a CCD is an older technology and usually slower, am I right? So I don't know if I should wait for Nikon or purchase a 20D now. I know lens should be a major consideration, but I am just having two cheaper lens and I plan to buy a better len. However, after I purchase this len. I will really stick to the brand for my life, haha. So I really have to make a BIG decision now! Anyway, thank you very much with all your expert and friendly opinions.

I'm saying this as an example but I bought my 20D because of it's frame rate (5/sec), features (both custom function and hardware), I already have some canon lenses, I'm familiar with how canon works already, and because of it's very low noise levels. Honestly, the 5 frames per second is what got me. The only downside is that it can only take 6 RAW images in a row before shooting much slower so that gives you a second and a fifth of continuous shooting. Aren't Nikon's NEF files actually smaller than the JPEGs? I know they smaller are at least on the D1. But the 20D can take about 24 large/fine JPEGs in a row. I believe that Nikon has a very good buffer system and I thought that they could keep shooting at least on the D70 at full res JPEGs until the card was full. Now, I don't know who would do that, but still. Also, I think the now Nikon should be out fairly soon since they just officially announced it. My Canon has 8.2 MP but that wasn't a real factor in choosing. I'm hoping that this sparks thought but I think that Nikon, having more professional level DSLRs (more expensive) and only (what will be) 2 consumer/prosumer level DSLRs might play a factor if you wanted to upgrade. I'm sure their consumer/prosumer cameras will upgrade too but since Canon started with DSLRs, there's been the Digital Rebel, the newer Rebel, the 10D and the 20D. That could either be good or bad depending on which way you look at it. Again, just trying to spark some thought to help your decision. I really like my 20D though. I'm sure you would be happy with either one and one probably isn't that much better than the other. I think a big part is just personal preference and how comfortable you feel with it in your hand.

Hi Again Ella!The Type Sensor In The Camera Has Nothing To Do With The Speed Of The Camera Both Nikon And Canon Make Great Cameras Other Factors Are Involved In The Speed Of The Camera. Andrew My D1X Produces Raw Files Averaging 7.75MB (Image Closed) At 3Frames A Second And Up To 14 Raw Before The Slowdown, This Is With The Buffer Upgraded Camera The File Opens At Around 17mb In Ps At 3008 X 1960 At A 240 Resulotion,At 3 Frames Per Sec Its Hard Enough To Compose Unless Your Trying To Capture Alot Of Action Its Like Shooting A Machine Gun After 3or4 Bursts Your Not Effective Anymore,But That Depends On Your Type Of Photography:-)
