Ooops took the microfibre cloth out of my bag and the 40mm pancake dropped on the floot

It was in a neoprene bag, but on opening I noticed, the lens cap had come off.

Really miffed as it fell from a sofa seat height onto a laminated wood floot so no carpet or underlay to soften the blow just one of those neoprene bags.

It was a superb copy, delivering brilliant images for the money!
Also its my get me out of jail card if I go somewhere that the 70 mm is too long.

How does one go about testing it!
Shoot and explode the image? At f2.8 and then f32?
Sadly As its only an emegency lens, I dont have any pics withthe current camera to compare.

If it works - will try tomorrow does that mean it survived or could it fail in the future?

Ant tips on checking out this fall damage ( if any ) is appreciated.
At least it was a cheap one. Oh well my first accident

How is the floot?

As everyone knows, a floot is actually a foot on the floor, so hope the OP is ok ߘ to answer the question, I would try focusing in manual and af from its extremes and listen for any horrible noises and then snap a chart at all apertures and pixel peep. If you're really concerned send it in for a service.

i dropped a vintage 50mm on a concrete floor a month or so ago, it bounced and rolled about 8 feet before coming to a rest under someone's chair at the bar. My super scientific test was to put it on the camera and take a few pics with it, it seemed fine.

Use it. If it works, it's fine. If it doesn't, it's broke.

I've had a 100 f/2.8L IS hit concrete, and a 70-200 f/4L IS fall onto one of the wooden walkways at Yellowstone. Both still work fine, and the pancake is lighter and less complex in construction than those two.

So is the OPs foot laminated with wood then? I'm confused.

I believe the OP wrote 'floot' mistakenly (the mistake is better than referring to his camera as a 'Cannon'!) and meant 'flute'

...which would account for the fact that his foot is fine after this incident (or is that 'dent'?). It must have been in a bag like this one, http://pema.sk …roje/taska-na-pan-flautu/ although made of neoprene for better cushioning.

Don't overthink it.

take some pictures. lens works? images acceptably sharp? autofocus and aperture work? carry on.

Heya,

I've dropped everything or had it hit something. Most of it just keeps on working.

The 40 pancake is a pretty simple and solid design. I'd expect it to survive a minor drop like that.

Just use it. Shoot it wide open on something to inspect sharpness and focus accuracy and look for any shifting of the plane. If it focuses properly, delivers sharp images, and doesn't make any really bad sounds that make you cringe while doing it, it's probably fine.

I actually found my pancake, with no caps, in the bottom of my backpack a while back, where it rode around freely in the bottom, getting slammed down, stuff shoved on it, etc, for several weeks. The glass is stronger than almost anything else that touches it. And the slamming on the floor and stuff didn't bother it either. It's a strong little lens.

Go shoot. Worry not.

Very best,

I can't see the reason to post this stuff. Mount the lens, if it focuses, and the aperture works, its fine. If not, you've got a $150.00 hocky puck. Why waste your time, and ours with such simple answers.

And yet, you wasted your time posting.

What he said.

On my first shoot with it, I dropped a 135L from my waist-high bag onto a basketball court. The hood popped off. No other damage. Of course, now I can shoot around corners with it. (JK, ) I don't think a 40mm STM weighs enough to be damage is such a short fall.

perfect advice! I dropped a 20D with 16-35mm attached to a tripod from eyelevel onto concrete once, if nothing else it convinced me that filters do nothing to prevent impact damage! lens still works well although the filter, less so.

He's doing a public service in trying to stop more silly threads like this.

Actually I know the op was looking for some definitive way to be 100% certain nothing is wrong but reality is just put it on the camera and use it. If somethings wrong with it but you can't tell then nothings wrong with it. If you can tell then you have an answer to your question as well
