The thing with the legs sitting in the grooves on the fire ring. It allows you to put a cast iron grate on it and sear your food right above the coals on a large. They sell them at the ceramic grill store.
Thats a Sigma 50mm 1.4. Love it but am still getting used to it as 1.4 is touchy. I took a picture of my cat at 1.4 and zoomed in on his eyes and his ears were blurry. An inch of depth off and you focus on the wrong thing.
You have 'depth of field' issues ... what camera are you using? Is it an SLR or point & shoot?
A fast shutter speed on low light will give you a very narrow depth of field.
Its a SLR. The depth of field issue was cause I was shooting at a 1.4 aperature. At 1.8-2.2 I would have gotten his whole head and at 3.5 his whole body would have come in clear. Or I could have selected more than 1 focal point and probably been good at 1.4. I have gotten used to it now and usually shoot at no less than 1.8 as 1.4 is touchy. Here's a couple photos I took at eggtoberfest playing with aperature. The egg photo was taken at 1.4 on a single focal point and the portrait was taken at a 2.2 with multiple focal points.
