The reason I’m telling you this is because for some reason you lose the “normal” or clear filter and still need to shoot with decent shutter speeds, you can just tape over the hole with electrical tape or other dark tape.

I took the filter out and fired off some shots, and didn’t notice any difference in exposures or focusing. I can’t think of too many situations where you would need it though. Note: Sony says these filters are figured in to the element count for the lens, and you have to have a filter installed to have the lens function correctly. The neutral density filter is good for two stops down, have your tripod ready. You should be using the “normal” filter for just about everything.

You really need a tripod for sharp images or bump your ISO up.Ībout the included filters: the lens comes with two filters, a “normal” and a “ND4” or “ND4X” Neutral density filter, Sony uses the two names interchangeably. Expect about half your shots to be sharp, and about a quarter to be tripod sharp. Normal daylight here in southern AZ allows shutter speeds around 1/125s to 1/400s at ISO 100 with this lens. At 500mm and F/8 in daylight, most people will need at least 1/300 sec for a sharp picture (or more) and that includes the use of image stabilization or Super SteadyShot, whichever you prefer. It has a fixed aperture (just a round hole), so you have to live at F/8. If you look down through the lens front, you’ll see yourself in the mirror at the bottom. If this lens design looks familiar, then you probably own a compact telescope or have seen one in a store, it’s basically the same thing.

The Sony 500mm F/8 reflex lens (made in Japan) is meant for people who don’t have a lot of money, but want to bring their subject up close. If you want an auto-focusing super telephoto lens for your Sony DSLR body and don’t have much coin, this may be your only hope.
