@danski0224 - All of your photos are beautiful. On my screen, however, they appear just a little flat. Have you tried them with higher contrast? Just a personal opinion, but I think they could use a bump in contrast (everything else is great).
I was wondering if the softness MrFotoFool referred to is the difference in focusing between infrared and visible light - I have had a camera fully converted and I understand that involves adjusting the sensor position to account for this.
No the focus on Danski's images seems fine. It is simply low contrast. One of the qualities of black and white infrared photography (based on the infrared film Kodak HIE) is very high contrast. This is necessary to get white foliage, which is (in my opinion) the main appeal.
I have a full spectrum modified 6D that I use for astro and infrared work - loads of fun Here's a few:
IR Church - 630nm IR filter + ND filter with blue/red channel swap
IR Lightning - 630nm IR filter no channel swapping
Windmill - as per IR church
Infrared Bridge Trees - 720nm IR filter on a stock 5D mark II with blue/red channel swap
IR Grass Trees - B+W 403 filter (bit like a 760nm IR filter, but also passes UV giving blue skies without channel swap)
