MacGyver eat your heart out!

12 02 2011

I have always loved the television show MacGyver. It always amazes me how he solves problems. Usually involving a trusty role of duct tape and everyday materials. I still believe that you can plug a leak in a nuclear reactor using a Hershey bar.
I think its that show that gives me a DIY attitude when it comes to my work. I have blogged before about my hacked tilt shift lens and how I managed to get apps on my Blackberry and now have another DIY lens project to share.
I bought a Telesar 135 f/2.8 Nikon mount lens in Brighton last year for 15 pounds and haven’t had time to mount it. By mounting it on an old lens cap cover, I managed to place it onto Canon 5D. Judging by the initial image samples, I am completely impressed with the image quality that the lens displays.

I have cropped a 100% sample at f/2.8 to illustrate how sharp it is.

That is without any initial sharpening so you can see how tack sharp it is.

As for the lens, there isn’t much information online regarding it. The only reference information I could find is on cameralensdatabase.

Canon EOS Experience at Raffles

13 12 2009

Sorry this is a bit late but I haven’t been able to upload photos onto my blog ever since I got my new laptop.
So am on Safari for the first time in years to post this.

I had a chance to play with the new Canon 100mm f/2.8 Macro IS L lens at the Canon EOS Experience Seminar at Raffles on Wednesday and Thursday.
Its an impressive lens which deserves the red ring that signifies it as an “Luxury” class lens. I wanted to see if the lens would be good as a portrait lens along with being a top notch Macro lens. The only drawback I experienced on the lens was the very loose focus ring which caused me to lose focus several times while in Manual Focus. It may easily be photographer error because of the very small depth of field f/2.8 allows at 100mm. So I guess I should say that I need to use the Auto Focus if I decide to get this lens!
There was an opportunity on Thursday morning with some models being brought out for the shooters. Here is a shot that really shows the sharpness of the lens.

I still don’t really understand why they did this as I was the only one of the participants that actually got to use one of the products that they were flogging. When actually thinking about it, I liken the experience of the seminar like going to Guitar World in Hollywood.
Anyhoo, another photo of the event.
