With the recent rise in popularity of the Peleng 8mm, I thought it was time to post up some samples.
The lense is great performer and a boatload of fun.
The Peleng is soft wide open and lense flare is a big concern. Stop the lense down to f/8 and this all goes away. Using the lense at f/8 and smaller apertures leaves you with a very dim viewfinder. There is a ring on the lense to adjust for this. The "Lock - Unlock" ring. It basically opens the lense up to the widest aperture letting in more light. Now you can compose your shot and possibly check DOF and focus (the viewfinder on my cam is too small, but on a 30d, maybe). When you are set, a twist of the ring stops it down to whatever you have it set for (f/8-f/16 in my case). The ring is very fluid and easy to use.
At f/8 it certainly isnt the best low-light lense to have, but with a flash, its still very usable. With an external (430ex/580ex/etc) flash on the camera, you can only have it pointed straight up if you use an omni-bounce or piece of tupperware, err, I mean lightsphere. The flash head sticks too far forward in any of the forward tilted positions and causes flare on the lense. Watch where you put your fingers too. If you hold the lense without thinking of hand placement, you will get a finger in the picture, or a halo of light refelcting off of your finger. Please keep all hands and feet behind the front of the lense at all times, for your own safety.
The lense is full time manual focus, but it isnt really an issue. There is a focus ring with a distance scale on it if you need to focus closer than 1m. I use the ring and just guestimate at what distance the subject is from me. I cant see the change in focus when I look down the hallway that is the viewfinder on the 350d and I am not really sure that the focus ring does anything, but I still do it. I am stubborn. It has worked out so far, but with the massive depth of field this lense offers, I havent noticed any OOF areas of the image. This is not a good lense if you love bokeh.
You can use the lense in Av mode (what I use most of the time) or full manual.
On to the samples.
The first shot is just a snap from when I was messing around with things. The shot is straight out of camera to show the vignetting. I believe exif is intact. It is f/8 (wont show in exif). The second shot is a 100% crop of that image. These shots are both untouched, no sharpening, nothing.
