IPD Discussion (was 8x32FL. Super-sweet? Semi-sweet?)



Recently there was some debate (I forget which post) about the size of the FL sweet spot, especially the 8x32. I've had my 8x32 for about a month now and am willing to say that the "super-sweet" spot is in fact fairly small, but that it is surrounded by a large "semi-sweet" donut, an area just a tiny bit less sharp.

As a result, I find that IPD on the Zeiss is more critical than on my other 8x32's. I was having fits trying to get both barrels super-sweet and then realized I generally had the IPD set a bit too wide. Narrowing it lined up the super-sweet spots and now these things rock. I notice that, like porros, it helps to narrow the IPD for closer distances--something that most roofs don't need except at minimum distances.

Any of this sound familiar? I'm curious about how others see this. If the FL's weren't so doggone sharp I doubt I'd ever have picked up on it.

Hello Mark,

Either this is a very personal thing, or I am not as critical as you are. I set the IPD and it works for me.
Yes, it an extraordinary binocular.

Happy bird watching,

Very good observation,..I am quite pleased with the sharpness that I can achieve with the FL 8x32,In fact I found it sharper than the Nikon SE,or as sharp,and to give such wide field without distortion and keeping the image quality so constant through the FOV is amazing.....You are right about the size of the sweet spot,But the sweet spot is VERY sharp,and the DOF is great for a 8x ,so usually i can carry either of my eyes to reach extra sharp images without any stress ,pretty much all around the ,WIDE,field of view..I found the FL extremely comfortable to hold and to look through.
