Canon Announces New Lens Caps!

I have to agree with trojdor in that the expense/quality/need of the equipment makes it a necessity to protect it. My lenses always have caps on in the Pelican case with hood reversed. When selecting a lens it's a very quick matter to drop the caps in the bay the lens came out of and flip the hood after attaching. I also use B+W filters so that I don't have to clean the lens element itself. I've had fingerprints smudge a lens element and found it a pita to clean on site, hence the filters. Fingerprints, sweat, dust are all a big problem when the vast majority of one's working days are in the 100 degree range. Easy enough to spin one off if necessary under time constraints.

Define professional tomusan? Define amateur? I don't do so much business that I can afford replacing lenses and/or repair work regularly, would prefer to keep my profits going where I choose. Just because I don't live on the high end of professionalism doesn't mean I depend any less on my equipment. I'll never understand why someone can get so challenging over the simplest of statements when others are trying to offer sage advice.

It's been my experience that years of experience don't necessarily make one better at what they do, all too often it just makes them very good at doing it wrong. Please take note the preface to this statement, IN MY EXPERIENCE. So if one doesn't want to be mistaken for a sniveling 19 yr old first timer, one shouldn't make such an obvious effort to sound like one!

I'm sure that as many people here are photographers there's at least that many different ways to approach the business.

Cudo's to Canon's attentiveness in a small detail. Will I purchase replacement lens caps due to the new design? Nope.

Finally, an answer to my question! See, it is not that hard...

By the way, please don't treat my like I am a 19 year old who just did his first job as a pro! I have 25 years of experience as a press photographer, so your comments about " learning from my mistakes" and "probably damaged more equipment than you owned" are highly unappopriate, wouldn't you agree?

I just launched my question (sorry to hear by the way you thought it was a bit too forward for your taste) because I wanted to hear from amat..., non- professionals (see, now you got me insecure about my spelling) why on earth they insist on using lens caps, when they have a tendency to 'over protect' their gear with filters, pouches and big camera bags while shooting peaceful landscapes, or fluffy animals in a zoo. That is not such a weird thing to wonder about, now is it?

Anyway, still looking forward to hearing from amateurs ;-) about the effects of not using lens caps (and tripping over wires, and dropping stuff doesn't count!)


Peace!

We're all professionals here - not one amateur. Didn't you know that?
Quite true. And I have a "professional" camera to prove it ;)

He he ... I wish being a "professional" would be so easy!

Anyhow, I use lens caps extensively unless I've stuck on a UV filter on the lens or have the hood on. Can't afford damage to my gear while on a "hobby" activity ;)

I'm waiting to see what the MTF charts look like, compared with the old ones. The DR too...how many stops? It could be a while though, with Canon's track record lately, they'll be $40-50 each and available "late 2013." Twice that for the ones with a red ring.

</sarcasm>

On a more serious note, has anyone actually done a study on using "dark frames" to calibrate sensor noise? Shoot a few frames with the lens-cap on (same exposure) and then shoot the subject... then "average" the dark frames and "subtract" them from the "real" shot in post, as in Astrophotography?

One wonders whether it may be possible to do the same "in-camera" by doing a pre-read of the sensor before the shutter actually opens...

I'm still trying to wrap my head around why someone would argue against using lens caps...
Every lens i've sold has been mint, not because i didn't use the daylights out of it but because I lens capped them and always used a hood, and I don't keep filters on my lenses for protection.

I think it was just that one professional not 19 yr old dude that hasn't used a lens cap since 2005! Everyone else agrees that they are quite important!

I wonder, are they weather resistant ? ;D

Dang u beat me to that point, weather sealed like the cpe-4 and the 580 exII and 600 flashes among others have all gotten the seal to protect against bad wether. Honestly keeping moisture out due to having some kind of sealing property may be useful. I like the idea of both caps having a seal as well as the cap that goes on a camera body, why the heck not!?

I feel like I'm the only person who has never had a problem with the Canon lens caps. Even when putting them on something like a 70-200 F/2.8 with the hood mounted, I've never had a problem doing so.
I have a tamron lens, and I do use the pinch feature of the lens cap but that sometimes results in the cap slipping out of my fingers and hitting the front element...

Hmm, I guess I'm just weird.

After 1Dx and 5D3 they seem to try to make us wait for a really useful product. After the introduction of 24-70 f/4L IS and 35 f/2 IS at such high prices, the new caps seem to be the culmination of their effort!

I have not had a problem either... So I guess we're both weird :)
