Canon FL 55mm f/1.2 lens onto EOS cameras

9 November 2011 4 comments

“Why would you want to do such a thing?”, you may ask. Simple. This legacy lens is solidly built, has superb optics (even when wide open), and does not cost an arm and a leg. I’ve had the pleasure of shooting with the Canon EF 50mm f/1.2L USM — the lens exhibits marshmallow-like sharpness wide open, and the ultrasonic motor leaves much to be desired (it’s REALLY slow for a USM). So, I decided to look for an alternative lens within the same focal range.

That’s when I stumbled upon the EdMika 55mm-conversion kit on eBay. I decided to give it a shot. Why not. It’s a quarter of the EF’s price tag, and the images are sharper with better tonal contrasts. The only “drawback” is that the focusing motor is your left hand — not so ultrasonic, but it’ll do.

1. Get your hands on a Canon FL 55mm f/1.2, which is somewhat hard to come by, but not so rare that it’s impossible. You might be able to find one at estate sales, your local camera shop, or eBay. I got mine at These usually got for $250-$400 depending on the condition. Just make sure there’s no fungus, and the usual used-gear precautions.

2. Order the EdMika 55mm-conversion kit, which comes with everything you need — including the screwdriver! They’re $124 + shipping (from Canada).

3. The kit also comes with 3 replacement-screws, plus an extra replacement-screw, and a spare ball-bearing.

4. You will need to remove the 3 original screws holding the FL mount onto the lens assembly. This only requires basic shop skills (i.e., righty-tighty, lefty-loosey).

5. Install the brass EF mount. The difficulty level is about a 2… out of 100. Super simple.

6. That’s it! Mount the lens onto your favorite Canon EOS, and start churning out the bokeh. One of the great things about this is that it’s not destructiveness — mount-swapping is reversible! So, keep the old FL mount in a safe place, in case you decide you want to use the lens on an older film camera.

Focus confirmation is achieved with a Dandelion chip. The chip that was attached to my copy was already pre-programmed for the 55mm f/1.2, so I could start cranking out photos as soon as I was finished tightening the last screw. The whole conversion took about 5 minutes — that’s with pauses to document the process. There’s also a YouTube video (not mine) that shows the whole process.

Happy shooting!

How to Jailbreak the iPhone OS 3.1.2

Precaution: Backup your iPhone! This should always be the first step when hacking into anything. In case you need a guide on how to do this, Apple has the instructions for creating and restoring a backup of your iPhone.

Install blackra1n:

Step 1. Download the blackra1n.exe file from

Step 2. Run the blackra1n.exe file from your PC.

Step 3. Click on make it ra1n.

Step 4. Your iPhone will go into recovery mode, and then reboot on its own (the screen will display a picture of GeoHot as the phone boots up).

Step 5. From your iPhone, run the blackra1n app.

Step 6. Choose an installer (I chose Cydia).

Note: Do not install Cydia and Icy at the same time!

Step 7. Once you’ve installed an installer, it’s safe to uninstall blackra1n.

Much mahalo and aloha to GeoHot for blackra1n.

DISCLAIMER: I do not advocate the jailbreaking of iPhone for the purpose of pirating, tethering, cracking, or other malevolent deeds.

If at first you don’t succeed… try another hack. If anyone has any suggestions, I’m all ears. My machine specs are listed in a previous entry.

Project Hackintosh

Macintosh SkullThe Premise:
I most-gladly scratched Windows Vista Ultimate out of my life, and installed Windows 7 Professional a couple of days ago.  It was an easy install, nothing out of the ordinary. Which is to say that the experience left me highly unsatisfied… no headaches, no hastle, no complications. Bleh. How atypical of Microsoft to roll out a new OS and not have it reek havoc. Thus…

I decided to start a new project this weekend, which will hopefully come to fruition with a little bit of frustration.

The Goal:
Be able to dual boot off of one notebook

Boundary Conditions:
No partitions
Use two different hard drives

Operating Systems:
Windows 7 Professional
Apple Snow Leopard (10.6)

The Canvas:
Sager NP9280
Intel Core 2 Quad Q9650 (3.00 GHz)
NVIDIA GeForce 9800M GTX (2 GB in SLI)
Hitachi HD (320 GB) – currently hosting Windows 7
Seagate HD (250 GB) – targeted home of OS X
