Lenses / Re: Canon prime rumors? 50mm f1.4, 85mm f1.8 and 100mm f2
« on: January 28, 2015, 10:02:41 AM »
Also note that the most recent IS primes all replaced lenses that were below the grade of the three you've listed.  One theory is that the 50 IS prime will replace the 50mm 1.8 II, not the 1.4, and that the 85mm might actually be a third slot.  I have not seen anything about the 100mm being replaced with an IS model.  Also, the new ones may not be as fast as the three you've listed -- 2.8 or 2.0 might be the limit.

But, yeah, the new 50 is going to be a big seller if it ever shows up.  Probably the 85, too, if they do one.

Lenses / Re: Used Gear stories....
« on: January 27, 2015, 03:52:28 PM »
I bought my 20mm used via ebay shortly before we embarked on a trip to Madagascar.  I tested out the lens quite thoroughly and was very happy with it, everything worked great.  I did not try out the hood, although I was glad to have it and packed it because of the 20's reputation for flare.  Shortly after we landed, I started fumbling around with it, trying to figure out why it wouldn't latch on, before realizing it was not a bayonet mount, but had to be screwed onto the filter rings.  Oops.  My bad.

I bought a few other lenses and cameras on ebay.  My only suggestions are to research the item you want thoroughly so that you know exactly what you are looking at in the pics and description, then follow sales listings for a while before buying.  I would rather spend a little more to get a better quality item.  My 28-105 came with the OEM hood (that also fits my 28/1.8 and was not available new at the time).  And skip anything with shoddy pics.  Either they are hiding flaws, or the photographer is so bad I don't trust their gear.

I wanted to know what you meant by using a beer cooler without having to listen to the audio, so I dug up this:

Turns out, he places a styrofoam disposable cooler over the subject's mounting platform, with the twin heads of the flash pointing up from the bottom for bouncing the light around the interior of the cooler, and with cut-outs for the lens and backdrop.

Canon General / Re: Photographer Petitions Canon for Left Handed Camera
« on: January 26, 2015, 10:25:08 AM »
I think it is far too much to hope to ever see a "left-handed" camera.  However, this seems like an excellent opportunity to develop a "left-handed" grip.  If Canon could divorce itself from the concept of forced obsolescence, at least for a moment, the left-grip could be universal and designed to interface with all, or most, body series.  That would help defray the development cost, since the grip could last through several camera life cycles.  Most of the smart functionality would operate through firmware anyway.  Since there is nobody else in this market, Canon could easily grab it up and get some good PR at the same time.

Hard to say if that is not true, or just bad PR from a marketing standpoint to say that your lens coatings are so fragile.

First time I have heard that. I must say I trust my breath a lot more than any chemicals which lens makers always advise against. But maybe I am wrong.

OK, Ken Rockwell says he breathes on his lenses before cleaning them.  So, that answers it.

How do you clean front element of your 200 2.0 when it gets dirty?

Simply use a clean photo lens cloth - just remember to breath on the lens first (as with any other lens).

I've been told that you're not supposed to breathe on the front element of a lens before cleaning it.  Use a proper lens cleaning solution and a clean lens cloth.  I found this article from Petapixel that confirmed the advice from Nikon not to breathe on your lens. http://petapixel.com/2012/12/07/your-breath-contains-harmful-acids-that-can-damage-camera-lenses/  However, the webpage from Nikon was apparently updated to remove the statement that breath could damage lens coatings.  https://support.nikonusa.com/app/answers/detail/a_id/539/~/how-do-i-clean-the-camera-lens?  Hard to say if that is not true, or just bad PR from a marketing standpoint to say that your lens coatings are so fragile.

PowerShot / Re: Convert the PowerShot N into a Rolleiflex Style Camera
« on: January 13, 2015, 05:43:03 PM »
Maybe I am just clueless but what is the point of doing this?  Other than to say that you can?  Is there some advantage to holding a camera like this?  People complain about not having a viewfinder and how unimaginablely difficult it is to frame a shot but with this you have to look down and not even close to where your subject is.  Please let me know if I am missing something.  Honestly I am curious what the draw to this is
Advantages of a camera at waist level? ???

Photographers with 1.8 meter high, shooting people comfortably with 1.2 meters? :P

Children are not included in this category because a powershot not have the necessary speed.

Metric conversions aside, I find the flippy screens useful for shooting from a different/lower angle.  The twisting side-hinge style (think 60D, 70D, or G1X mark I) allows you to get low for horizontals or verticals.  The top-hinge style (i.e G1X mark II or G7X) is a bit more sleek but seems like it would not allow for low-angle vertical framing, although I have not yet used one.  Much easier on the knees.

Pricewatch Deals / Re: B&H Photo Nows Carries Yongnuo Products
« on: January 11, 2015, 03:51:40 PM »
In fact, I don't see how B&H could/would list and sell the lens if it were a true copyright infringement.  Yongnuo's business is certainly NOT worth endangering their business with Canon over.

That was my first thought when I saw this post.  Obviously, third-party manufacturers have been reverse-engineering Canon products for years (i.e Sigma/Tamron and autofocus protocols).  I thought the RT flash programming might have been different, as I could really see Canon getting aggressive about that.  Interestingly, I don't see Yongnuo's 600-EX-RT flash on B&H, but they do have the EX-RT transmitter.

Live view users: wear a broad brimmed hat - helps immensely in reducing glare - and prevents sun-exposure skin cancers.

Dunno why, as soon as I wear a hat I have this itch to shoot in portrait mode and the hat brim interfere :(

NancyP is talking about a floppy soft-brimmed hat, not a baseball cap.  I wore one when we went to Madagascar, never a problem switching to vertical orientation.

Software & Accessories / Re: Bag for tripod?
« on: January 07, 2015, 10:51:00 AM »
My tripod came with a bag.  If it hadn't, I probably would not have purchased one.  It is nice for carrying it around the house and out to the car, or keeping it from banging around in the trunk.  Once you get to your destination, take the sticks out of the bag and leave them out, or you'll never bother setting them up.

EOS Bodies / Re: 2015 wishlist
« on: January 06, 2015, 10:55:39 AM »

Here's an idea. Not super-useful but interesting.

Especially on wifi-equipped bodies (and cell if they add one):

-Camera keeps track of the lens serial numbers it is using. And minimum once every few month it would connect to an online database (run by Canon) to check if the lenses (or bodies) are on stolen-list. If yes, it would blacklist that body/lens and you cannot use it anymore. If you don't connect to the database, it would eventually blacklist (locally) everything you have, until you connect again.

Benefits:
-If gear is stolen, you could blacklist them and they would be next to worthless for the thief. -> less stolen cameras

Drawback:
-You need to connect camera every so often. This could be done also over the USB, so when you connect to download images, it'd also check the database. With wifi or cell models, it could be automatic in the background so user doesn't even know about it. Same for USB too.

Of course it cannot just suddenly shut down your camera, if you've had it in storage for a while and suddenly need to take pictures. There should be timer, e.g. if you turn it on for the first time since it's already past due the check, it'd blink on the screen that you have 5 extra days to do the connection.

Also there needs to be good way to implement how you send in the data. Only registered buyer or something, so you cannot blacklist you're ugly neighbors new 200-400 just because you hate him. But it needs to be easy/fast enough that if your gear gets stolen, you have it up at the list soon enough that the thief cannot sell the gear.

So if anyone is buying gear, they'd meet up at Starbucks, connect the camera to wifi or laptop and run the check. Then if it clears, you go ahead to buy the stuff.

I can't really see anything that would be bad on that system, and if it would reduce stolen cameras, that'd be awesome.

Canon, please implement, ok?

While you're at it, why not throw in a monthly fee per gear item?  So we can keep paying every month for gear we already bought. 

OK, that was sarcasm.  Just get insurance if you are worried about theft.  I don't want to worry about whether or not a particular camera or lens has "checked in" with Canon recently enough every time I want to take a picture.  Canon can barely implement wifi on a camera to send images to your phone, let alone all of that nonsense above.

Third Party Manufacturers / Re: Yongnuo 35mm f/2 Canon Clone on the Way
« on: January 05, 2015, 12:02:32 PM »
Well, if this keeps up, we may soon see a Yongnuo 24mm 2.8 and/or 28mm 2.8.  I would also be curious to know when the patents on these older lenses expire(d).  There isn't one at 85 or 100, though, and I doubt Yongnuo would try to replicate the 135 2.8 softfocus (although maybe without that little feature). 

Personally, I like the idea.  I'd love to put together a super-cheap prime trio for my film set-up.  Also would be a great way to get somebody started on primes with their new Rebel.  Imagine hitting all the basic focal lengths for $200 -- now go see what focal lengths you like, and upgrade accordingly.

Seems like a lot of lens swaps, unless you're also taking multiple bodies.

For travel, I would probably replace the 16-35 and 24-70 with the 24-105 (presuming you have one) and leave the 300 at home.

I wouldn't (at least as far as the wide/standard zooms are concerned).  If you've made the decision to bring five lenses, I presume you know what you're doing, where you're going, and how you plan on using them.  I never understand why people complain about changing lenses.  That's the whole point of having a camera system like this.  Sure, the 24-105 is good, but the 24-70 is great (in my experience) and so is the new 16-35 (according to most reviews).  With the overlap between the standard and the ultrawide, I'm sure you can gauge which is more appropriate for the situation and manage accordingly, even if you only have one body.

As for the 300, it all depends on where you're going and what you're photographing, which we don't know.  I'd love to hear your thoughts on it, because I don't hear about it much and I'm curious for real-world opinions.  It seems like a nice budget telephoto option for those of us who won't ever buy a great white.

The proper term would be either pentad or quintet.  But I probably would've called it The Pentaverate.
