I have regained my interest in photography since I bought a used Fuji s5700.

I used to shoot 35mm with my Pentax me super many years ago.

My question is relating to iso, are the film and digital iso`s the same or slightly different? At one time the best all round film speed was iso 100 for 35mm then later the iso 200 due to advances in film quality, iso 400 was best for night shots or telephoto where a faster shutter speed might be needed.

I have seen some examples of using different iso`s in reviews for my camera, they seem to be pretty good results up to iso 400, above that the grain becomes too much.

Would I be better setting the following manually?

ISO 64 bright sunshine
100 sunny
200 overcast
400 night

I would appreciate your advice please
 
Modern digital cameras are very very good at high ISO, not familiar with your camera but I wouldn't be surprised if ISO 800 was completely usable if you're not pixel peeping at 100%.

As to which one to use, well I just check what my shutter speed looks like and select an appropriate ISO to give me the speed I need. Hey I even use auto-ISO sometimes :)

Iso 100 is probably the native low iso on the camera, I wouldn't go below it if not needed.
 
The s5700 is one of the older fuji bridges. A bit like mine, it is probably not too hot at high ISO.

The more modern fuji bridges are much better.

The best thing to do is to experiment and see what you are happy with noise wise.
 
Digital iso vs film iso - as far as sensitivity is concerned is exactly the same - but as far a quality is concerned they are worlds apart. Modern DSLRs like the D3 and D3s can shoot up to 6,400ISO or higher with amazing results.

It looks like a great extra option over 35mm, it is like being able to stop mid film and change the iso. I will probably use iso 100 as my norm as you recommend and use the others as required. might need iso 64 for Turkey this year, at least I hope the weather doesn`t let us down.:cool:

Thank you`s to you all for your replies.
 
It depends really - some cameras take to trying to get rid of the noise which creates mush, or others leave it and you get grain. Personally, I much prefer grain as I can then reduce it selectively in Aperture. Once the cameras reduced it to mush...not much you can do. My gran used to have an S5700, and I think it was quite good higher up the ISO. sure o remebr using 800 and them printing fine at A4. Just experiement and see what you think :)

I also prefer the grain.. And shoot RAW so the camera has no say in noise reduction ;)
