Lenses / Re: Why I love the 200mm f2.0 prime

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.

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

-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.

It looks great, at least on our little web version here.  I'd love to hear more about your techniques for shooting and stacking, particularly the gear (rail, flash, etc) and software used.

This is really just a quiet way of saying "We won't cover repairs to your speedlite under warranty if you tell us you used lithium batteries."

Lenses / Re: Buying Advice: What First Lens for a Full Frame?
« on: December 16, 2014, 06:15:57 PM »
A good versatile lens would be a standard zoom, like 24-105 or 24-70.  The 24-70/2.8 MkII is probably out of your budget.  Consider a "white box" 24-105 F/4L or the new 24-105 3.5-5.6 IS STM.  I went with the 24-70 F/4 because I wanted something light, small, and constant aperture.  I love it but others are picky.  It is a little more expensive than those two choices.

Software & Accessories / Re: ND and Graduated ND Filters?
« on: December 11, 2014, 10:52:21 AM »
You might find a screw-on 3-stop useful to use your 35mm at maximum aperture in bright light.  I do that with the nifty fifty sometimes.  Rather than sticking at 67mm, I would suggest you up-size to your largest filter size (current or possible) and use a step-up ring.

But the conventional thought on introducing motion blur is that you need 6 or 10-stop filters, (i.e. the Lee Little Stopper and Big Stopper, respectively).  That seems like a lot of filter and hardware to hang off the front of the 10-18.
