Tamron 28 75 f/2.8 lens review (HD viewing)

Tamron 28 75 f/2.8 lens review (HD viewing) Video Clips. Duration : 3.32 Mins.

I can't say enough about this little lens from Tamron. Stop using lenes which sift the aperture over the zoom length. Pros will always use lenes with an apeture of f/2.8 or faster.

Sigma has released their latest fast-apertured prime in the form of an 85mm f/1.4, a popular focal length for portrait photographers. With Nikon and Canon's offerings costing a considerable amount more, does the Sigma offer up enough quality to be a good enough alternative to the big brands' lenses? Is it sharp? What's the bokeh like? Find out in this video.

Helios 135mm f/2.8 M42 Lens Review (On Canon EOS 350d)

Helios 135mm f/2.8 M42 Lens Review (On Canon EOS 350d) Tube. Duration : 6.97 Mins.

www.robnunnphoto.com A bargain prime lens I got from a local car-boot sale for about a fiver. The Helios 135mm f offers a fixed focal length (no zoom), so you've got to move your feet to recompose or change the framing of your photographs - not a bad thing when it comes to expanding your artistic vision. M42 lenses need an M42 - EF lens mount adapter, available on eBay for a few pounds, you've got to focus manually, but they're perfectly usable. Cheers, Rob.
