So, as some might know, I've been in the market for some longer glass, seeing as my previous kit had only a 35 f/2, 50 f/1.8, and 85 f/1.2L II USM.
I ended up ordering a 300mm f/4L IS USM, as well as a classic 80-200mm f/2.8L, aka "The Magic Drainpipe"
Here's what the MDP and 300mm look like compared to the 85mm f/1.2L II:
The MDP is a nice, RAZOR SHARP piece of glass. I'm impressed with it. However, I broke the one part on it that I didn't want to, the AF/MF switch :(
Unfortunately, this little piece of plastic is almost impossible to find, and even if you DO find one, the prices on them go from $60 to a whopping $200.
Here's the damage:
So, being an ex-electrical engineering major, I decided that I should utilize the technology we have at our disposal, and create a 3D printed switch that will replace the old one. For anyone wondering, here's the measurements of the old switch:
Now, the plan is to utilize the measurements I took (all of the above are in mm, if you're wondering), and create a 3D model of the part. I've got a plan, a person to double check my file before sending it off, and a company to print the part. If this works, I'll be making the file available for the world, so that any other MDP owners who may have come across this problem are saved the agony of being stuck in one AF mode (Lucky for me it died in 1.8m-Infinity AF mode, not MF.
Expect updates with the model as I get it done. This will be a fun saga!
