Thanks for your reply.mjkzz wrote:Carlos, if that item on eBay is plastic, then it could work if you cut the top off a bit. What I am concerned is that the large opening (where it is connected to a speedlite) seems to be too small, you will get stray lights entering lens, causing hazy images, even with lens hood (self made one with black paper). But from the weight (303 grams), it might be made of glass, in that case, it is hard to cut them if cuttable.
My final version has about 13.5cm opening in the back and about 5cm in the front (where camera is at). It works well for lenses with working distance less than 10CM but greater than 1cm and is thin so it can be partially inside the globe.
For lenses with longer working distance, I think I need larger globe, otherwise, the lens will be outside the globe and reflection of the globe can cause haze.
Hope this helps.
It seems to be easy to find other alternatives of different sizes and made of acrylic or polycarbonate, as we can see in eBay item number 282445175786 or as we can see in the image of the 263329203405.
These solutions need to be worked to have some utility as a diffuser as you describe, but, however, I still can not figure out exactly how to hold the globe for horizontal use. What solution did you use to fix the globe?
Thanks in advance,
