Canon 40D Owners Past and Present ISO Question

The longer I have had this camera the more I realized the limited range of use for ISO settings. Great camera in may ways but still I am finding limitations that have me considering a replacement such as the 7DMII.
My question is this, what is the highest ISO setting you are willing to use and have acceptible results. In my case up to 800 is about the tops. Just wondering where others draw a line in the sand. Thanks in advance.

I have gone as high at 2500.

I don't have a 40D, but I do have a 50D, and with the 50D I was only able to go to 1600, so 800 on the 40D sounds reasonable. If you are going to upgrade, a 7D Mk II would be a good choice if you are a sports/action photographer. If you are a landscape/portrait photographer, I'd lean more toward the full from 5D Mk II.

I used the 40D for 6 years and didn't go past 800 very often because of the noise.
Here is a reasonable comparison of ISO and noise - (scroll down to the Cadillac shots...

Thanks for the responses. I'm a little surprised by the 2500 ISO setting but I suppose with skills at killing noise one could manage that. It appears my experiences generally are in line with others. If I upgrade it will likely be the 7DMII. My grandchildren are growing and getting more involved in sports so I really want to be able to capture their participation. I do like landscapes as well and believe the 7DMII could be used for that. The value of the 40D is now such that I may as well keep it as a back up. That is unless I got an offer I couldn't refuse.

Agree. 800 was tops except in extreme emergencies. I figured a noisy shot at 3200 was better than nothing. ISO limitation was the reason I upgraded to a MKII. Gave my 40D to my brother who loves it. He does mostly family gatherings and uses a strobe.

Generally speaking, I try to stay two ISO values less than the normally found values.

Many of the post edit programs have noise reduction portions that might help out your older camera.

The highest I have used with any luck was 1600 ISO using a 105 mm 2.8 for night time high school football but I wouldn't use anything over 800 and if the action was too fast for 800 ISO I would pop a little fill flash to stop the action. That being said I also have. 5dII and don't use the 40d for much indoor shots with out some fill flash. I am planning on replacing my 40 d in a couple of months with a 7dII, so I guess it just comes down to the sensor is too dated for any high ISO. Use

I haven't owned the 40D but I have had the 60D and still have a 7D. I found it frustrating at times when I needed to up the ISO to get a fast enough shutter speed to get away from image blur the photo would be noisy. I bought a 6D and am very happy with being able to do higher ISO and longer exposures without noise. In the future I plan on changing out my 7D for the 7DII for the higher frame rate, dual card slots, better focus system, higher ISO capability, etc. Although the 40D is a good camera I think you would be happy with the 7DII if it is in your budget. I hope this helps.

Still have my 40D and agree 800 is acceptable noise in most cases. Have used it beyond that, but relied on 1.4/1.8 lenses to get me through. Outdoors, or with flash, and /or with the right lens, the 40D is still a beast. Years ago, the 40D was one model one of our local stores would rent, because they were so solid and reliable, and they rented them a lot. Technology is fast leaving this model to the DSLR museum so to speak. Still fun to shoot though. In a pinch, you can use a de-noiser to help if you have to max it out to 3200.
If you haven't got a lot invested in lenses, would look closely at a Nikon D7100. Much better in low-light situations with their Sony sensors for less money. IMHO, one of the best APS-C sports cameras out there. BTW - I shoot Canon. That may change when I learn the menu settings on my Sony a6000 which is on Santa's UPS sled. The 6000 is allegedly lighter, faster, smaller, than any DSLR on the market today.
On special from B&H $448 - body only will adapt to Canon lenses. Cheaper adapters - manual focus only. High end adapters get you AF. Some of the adapters are as much as the camera!lol Sorry if this is too much info. Good hunting.

The answer is " you go as high as you have to to get the shot". Why does canon offer crazy high ISO like the 5D mark III? So you can use it. Just use the lowest ISO possible to get the shot but also as high as necessary to get the shot. Better than no shot at all. Some star photography expert use up to 12800. Good luck
