comment Capturing fast moments, such as bullet
@gpuguy (1) As Michael said, shutter speed is largely irrelevant. = slow enough. Maybe even "bulb". (2) Assuming that the photos is not doctored: Bullet speed should be arranged to be as slow as possible without adversely affecting the affect on the target. Say bullet was travelling at 100 feet per second. Bullet is ~~~ 1 inch long and has moved a maximum of 5% of its length - maybe less. So 1 inch x 5% / 100 feet/sec = 1/24,000 th of a second or about 40 uS. At 1000 fps that would be 4 uS. 1 uS would be even better. ....

comment 50mm stuck on the body
@user1515834 .... DxO lens evaluations suggest that the MkII (Mk1 apparently not tested) is an acceptable but not stunning performer and if I owned one then say $15 plus an hour or few of fun would probably be worth expending in this manner. Each to their own.

comment 50mm stuck on the body
@user1515834 It's a shame that Canon reduced quality below an acceptable level in this manner. BUT note that the replacement plate that HackinGuiy identified for $US9.99 is made of metal (probably due to the failures) and is likely not to fail in the same way. It looks like it MAY be worthwhile for owners of these lenses to change or modify the bases plate prior to failures occurring. ....

comment Portable battery charger
@Rene "no need" and "would be exceedingly useful" vary. Ability to charge from USB port on a netbook can be very handy. Charging from a power bank can be life saving. Depend son how portable you need or want.

comment Camera lens or megapixel value: which defines the quality and clarity of the picture?
@Jan'Saffi'Stekelgunsson - " .... Instagram filters .... still they often come across as great looking photos, right?" -> Vanishingly seldom.

@HackinGuiy I don't know if the later model II cover fits your lens But, note that that company is offering parts installation service and may offer complete repair at an acceptable price. Whether that's a good choice is up to you.
