Ah yes,...Tungsten film. Forgot about that.
Well, my only issue with the V500 is the flimsy negative holders. However, they only come into play with 35mm film. You can also scan 120 film as well 35mm slides that are still encased in their little cardboard carriers. Oh,...one other issue I have with it is that it won't do an accurate "preview" of 120 film. In other words, with 35mm film the scanner will show you a small color corrected preview of each frame you have loaded before you hit the scan button. (You can load up to 12 frames at one time by the way.) You can make some batch adjustments to the preview images. For example, you could flip them all horizontal at once or vertical or you could inverse them all at once (which sometimes comes in handy when you are compelled to load a film strip backwards due to curl), etc. So, being able to preview is a nice feature. But for some reason, although you are supposed to be able to preview 120, it never seems to select the frame properly. You may only get half the frame. So preview is NG for 120. (You can still make pre-scan adjustments, you just have to do it individually for each 120 frame. However, this wouldn't be an issue for you at this stage of your film shooting since you're not shooting 120 yet I don't think.) By the way, as I mentioned you can load 12 35mm images at a time, but this is for a strip of negs. If you have slides already encased in their cardboard or plastic holders, you can load 4 at a time maximum. (I think you said you had some old slides to scan...?)
