Aparture that creates bokeh, this is a consideration when I think about a big aparture. How much differences are there between each aparture range? Luckily my cousin lend me an antique canon lense, a 50mm f 1.4 canon fd SSC. Hey, that's a great opportunity to satisfy my curiosity.
Ok, let's begin! Here's my settings to the equipment. A tripod. A GF-1 camera lens plus a 50mm manual fd 1.4 and an adapter. Iso was set to 100. The distance to the object about 60 cm, as well as the distance to the background object. Due to the manual setting and old lens, the existing aparture record is not listed on the image properties of each image. There was only iso and shutter speed records.
For the determining the apartures, I see directly from the numbers listed on the lens. 1.4-x-2-x-2.8-x-4-x-5.6-x-8-x-11-x-16 (x is a value that is not written on the lens). This x number probably not to accurate since it's not detected in the LCD panel, but hopefully it will not be more than 1 stop. The focus of the lens is on the lens cap. The photos maybe small but you can enlarge the photos anyway.
