I've been thinking about getting an IR filter but from the threads I read most indicated a Hoya or Cokin filter would work the best. But they are pricey. I was contemplating a cheaper Chinese version and your results with the Opteka IR filter gives me some sense of what can be accomplished.
Thanks for sharing.
This was partly my purpose in buying the filter. I was curious if the K-7 could achieve decent results without spending almost $100 on a filter. First, I wasn't even sure that the IR could get pass the built in filter, so if it didn't work then I'd be out a bunch of money. Second, I wondered if the cheap filters work very well as most of the feedback is about Hoya, etc.
Since I'm using the kit lens, the cheap filter gives me a pretty good look at the minimum IR quality that the K-7 is capable of. If I were using a nice fast prime lens with a higher quality filter I am sure you could achieve some very nice results. It also helps if you know exactly what you are doing with Photoshop, as I am still in the learning phase with post-processing.
I have a 50mm 1:1.7 that I used briefly after I took the images above. At f/2 there was no vignetting and the overall images looked pretty good. However the wind had picked up and every image was pretty blurry, so I haven't processed them. Will try again next week when I get back from an out-of-state wedding.
