02Jul Crop sensor EF-S lens on a full frame body, Vignetting with the Sigma 30mm f1.4

More from the new DSLR FILM NOOB Channel. The labeling of a crop sensor lens can be confusing. The Sigma 30mm f1.4 for example is labeled as a 30mm lens, but since it’s really only designed to work on a crop sensor camera, it has an equivelent focal length of 48mm (1.6 times 30). So […]

28Jun Canon 40mm f2.8 lens has very strong vignetting (light fall off)

I had a little bit of time last night to capture a few test shots with the Canon 40mm f2.8 lens. Corner and center sharpness look very good for a lens in this price range, however the Vignetting is very strong wide open and doesn’t completely clear up until about f5.6. The focusing speed of […]

27Jun Canon 40mm f2.8 STM – First impressions

The Canon 40mm f2.8 STM lens showed up on my door step this afternoon. The box is much larger then it needs to be for this tiny little lens and because of that, the lens is swaddled in bubble wrap.  The box is so light that it almost feels empty. The first thing you’ll notice when you […]

15Jun Canon 40mm f2.8 STM pancake lens

Slightly thicker then 2 stacked body caps, the 40mm f2.8 STM lens represents Canon’s first modern pancake lens. I have no idea whether or not this lens will spark a new line of mirrorless Canon cameras, but it is a refreshing change of concept when compared to the rest of Canon’s lineup. The STM designation stands for Stepper motor which is a slightly […]

17May Tamron AF 28-75mm f/2.8 SP XR Di LD Macro

Time to remove yet another lens from my bag. The Tamron 28-75mm f2.8 lens has a very useful focal range on a full frame camera and gives you a lot of reach on a crop sensor camera. Tamron Claims this is a Macro, but 1:3.9 doesn’t quit make it. However that does mean you can […]

11May Tamron 17-50mm f2.8 Di II SP LD XR IF

My lens collection is getting a little out of control and it’s time to start thinning the herd. The Tamron 17-50mm f2.8 is a great fixed f-stop zoom lens for the price, but it’s only designed for crop sensor cameras like the t2i. Although this lens is a good value, it hasn’t left my bag […]

14Apr Chipped lens adapter problems with the 5d mark III

Using older manual focus lenses for filming is a very common practice among DSLR film makers, and a chipped lens adapters on the Canon 5d mark II (or any DSLR for that matter) is a good way to save some money on lenses and provide  focus confirmation with these older manual focus lenses. Above is the Tokina 500mm […]

02Mar Canon 5d mark III announced! Pre-Order body only available.

After an extremely long wait, the Canon 5d mark III has finally been announced and it looks like Canon was kind enough to grant most of the things on my wish list. So lets take a closer look at what made it into the camera. Advanced video codec ALL-I Proper Headphone jack Extended recording time of […]

29Dec Canon 80-200mm F2.8 L legacy lens

Canon’s been making EF mount lenses for a long time and there are a lot of discontinued L series lenses that have been retired over the years. The older lenses are sometimes missing some of the new features like Full time manual focus or ultra sonic motors, but the build quality is still solid and the optics […]

27Dec Canon 70-200mm f2.8 L IS was under the tree this year.

I just made it back from the holiday break and under the Christmas tree this year was the Canon 70-200mm f2.8 IS in all of its glory. This was actually a gift I bought for myself with the proceeds from a job I just finished up and the price was surprisingly less then I had expected. The Canon 70-200mm f2.8 […]
