Without a doubt! Especially if it was outdoors, in the rain.

Seriously, I wonder if anyone has taken anything other than a 1 series to the rainforest, places like the amazon, or Borneo...or even just central america.

Rainforest... Check. Central America... Check.

Which body was it, and how did you deal with the moisture and humidity?

Question for owners of Canon 200mm f2.0 and 70-200mm f 2.8 II lens

Studio 1930, it looks like the dog on the left thinks it's about to get a treat. I hope it got one! I love the bokeh of the lights...and again...the color and contrast of that lens...it's just magic.

I really wish I owned a 200 f/2. Hopefully someday. I think I may post a shot I did with the one I rented in fall 2011, in a landscape photo contest...assuming it hasn't already been closed (and assuming I can still log in). I'm sure it won't go anywhere, though...especially since it's a "portrait" oriented shot. They don't seem to like those. They always prefer a wide angle shot done in one of the parks in the Rockies, or Yosemite. Mine was "only" done in Appalachia...

IS mandatory? 70-200 f/4 IS vs. f/2.8 Non-IS

dexstrose said:
Thanks Paul13walnut! I always wondered about that. I thought you had to shoot at 2.8 all the time.



paul13walnut5 said:
No.

From the mid sixties most SLR cameras have had full aperture TTL metering.

That is the iris stops down to shooting aperture at exposure, it remains open before exposure to keep the viewfinder bright for focusing. Meter coupling, and these days electronic interfaces, tell the meter how much to compensate the reading for.

So if you have an f2.8 or faster lens, the af is performed at f2.8 or faster, even if you shoot at f8 all the time.

If you want to see what your sensor will see when the shutter is activated, use the DOF preview button on your camera. For many Canons, it is on the lower side of the lens mount away from the shutter button. On the 5D mark iii, it was moved to the shutter side of the mount. Regardless, find it on your body and before you take the picture, press and hold that DOF preview button. It will stop down the aperture to your set value and you can see through the viewfinder or live view the actual light amount (and Depth of Field).

Lightweight lens for backpacking and bicycle touring

7D is a heavy camera. How about bringing a T4i

Or an SL1, even smaller and lighter.

Good suggestions, but the next camera I buy is either going to be a P&S or a full frame (which brings up the debate between the 6d and the 5d mk iii)

sdsr- thanks for the advice about the Tamron's poor IQ.

-regarding a tripod, I've thought about simply bringing a Joby Gorillapod (or similar equivalent) and attaching that to the bike frame.

New review of the Sigma 30mm f/1.4

JAlmodovar90 said:
Has anyone gotten there hands on the lens yet? Would it worth getting the 35 1.4 for crop despite the 30 being specifically built for crop?
The Sigma 35mm f/1.4 is much larger and heavier so make sure that is not an issue. The resale on a FF lens like the Sigma 35mm will be higher most likely and the image quality on a cropped camera will be better than the 30mm f/1.4. Plus, if you ever upgrade to FF or rent/borrow a FF camera, the lens will work. It's probably worth it to go with the 35mm IF you don't mind the size, weight, and have the extra $400.

Recommendation for lens 18-20 mm

RGF said:
big, heavy, cumbersome and expensive
There is the Nikon 14-24 but it is awkward to use

Other recommendation? Nothing in the Canon lineup seems to fill the gap without giving up on IQ. Any recommendations.

Thanks
Considering your above mentioned problems, I don't think any lens in Canon/Nikon stable will meet your needs ... IMHO only option is to compromise with 16-35 f/2.8 L II

How do you buy equipment?

kennephoto said:
I hear ya and I do the same thing pay off my credit card every month and haven't paid interest on either card. Guess I should as for a raise haha. What do you mean pay yourself at variable interest rates?
It means that on months when there is a lot of money left, i repay more, on months when there is less left, I repay less. In the end, I repay a little more than I took, so my savings account ends up with a net profit. (it's kinda linked to what my wife looks good in and how much the latest drresses cost as well :)

Racetrack Playa in Death Valley

It sure is an awesome place. You need to go there soon as people have been moving and stealing rocks. Everytime I go one or two rocks that I've shot in the past have disappeared and all that's left are their tracks. Another sad part is that there are people who have driven their vehicles on the playa with leaving tire marks.

Awesome location and shot! I would love to go there.

black rapid

bycostello said:

Hilarious, love it.

But there's a better option, less destructive. On my own Black rapid Straps (I have several), the "Loose" end has a Plastic Buckle on it that has a "gap" in one side, slip the strap through the "gap" disconnecting the strap from the belt, then slide the Plastic Buckle out of the end loop using the same "Gap" int he Buckle, the Strap will now slip through Plastic Buckle attached to the Shoulder piece where you shorten/lengthen the strap, you now have a loose end, fit your new R2 Buckle & reverse the procedure.

Shouldn't require the use of scissors, knives or any other sharp instrument.

Boston

Hey guys! I'm sure you're all aware of the terrible explosions in Boston. Just another sign of how street photography can be dangerous sometimes, especially when we don't think about it and don't expect anything like that. I hope none of those who live in Boston or visited it yesterday got injured. Take care!

As a Bostonian I certainly appreciate this. Let's be careful though not to take the real and perceived dangers out of perspective. Despite the discomfort that we sure all feel at this point at the sight of trash cans let alone the 24-h "news" coverage of it we should not stop doing what we're all doing. The likelihood of falling victim to whatever insane kind of person responsible for this is pretty small compared to our everyday risks. You're very likely more at risk of being hit by a car or falling off a ladder still.

And I say this as someone who only wasn't right there at that time due to a scheduling conflict...

+2. All my thoughts to people of Boston. Stay strong. A very memorable vacation at one one time in my life. Being a lifetime Bruins fan I visited the gardens the year before they tore them down. Now I have two NHL teams close to the heart. Jets and Bruins

Indoor Skydiving: iFly

Apparently iFly was on NikonRumors and got sick of it and sold all their gear and switched to Canon ;D ;D ;D

---

Seriously though . . .

---

I took my boy to iFly (indoor skydiving) and saw the canon camera behind the glass.

They had the benefit of front-lighting, I was fighting that light from the back (won't know until I get home how well I did since I'll have to post-process for the lighting).

Bought a pic as a hedge against my still growing skills with the Tamron 24-70; I was mostly paying for the curiosity of the exif . . .

THAT said, I got what I wanted for $4:
They're using a 50D w/ 10-22mm.

Glass/plexiglass is truly my nemesis; I hate seeing my fat arse in the dang image ;) I had both of my high-end filters, which DID NOT fit my lens (did I mention I'm still learning on the Tamron?) . . .

I'm going to scrutinize the image when I get home, but it was ISO 1600 and I was at 6400 with the 5DmkII, so wish me luck

Results: Filming 720p 60fps at super high shutter speeds

This is just plain awesome 8)

acelegendary said:
Hey there,

Long time reader, first time poster.

I recently filmed an engagement session, and wanted to utilize a shallow depth of field in bright light without an ND filter. So, knowing that I would end up slowing the footage down to 40%, I cranked up the shutter speed in order to hit around f/2. The results? Well, see for yourself:

Will the 70d have a new sensor?

ankorwatt said:
sorry, no I said only that you do not lose anything with higher resolution in a sensor regardless which lens you use, look at page 6, do I need to add that OFFCOURSE it is the same sensor size we are talking about

And I think you are a little bit rude when you are talking about the same bull sh...
it's derogatory (nice word I found)

Your the type who backtalks, quibbles, beats around the bush, dodges direct questions, obfuscates, etc. in order to make your arguments. If you would just directly answer peoples questions, you wouldn't have so many problems. Because you DO do those things, well...people don't trust you. And, every time you get involved, the conversation tends to go downhill, into the death spiral of you perpetually blanket stating "Canon Sucks", and everyone else trying to present reasonable arguments as to why they don't suck...they just aren't the best of the best at sensors "currently".

Everyone knows you hate Canon, and no one cares. I'm just curious when you'll actually pick up on that fact...

Patent: EF 400 f/4 DO IS II

GMCPhotographics said:
Which leaves one to wonder if they no longer have that capability or they outsourced the original FD lens optics, which would explain why it's so darn expensive!

Had Canon outsourced production of the lens elements, they would have been cheaper, not more expensive. And they'd very likely still be available today, even if not packaged and sold by Canon.

That's because Canon wouldn't have outsourced to somebody smaller or less capable than themselves; they'd have outsourced to somebody who was already making such lenses, somebody who had already sunk the cost in R&D and tooling and what-not. Somebody whose own operation was so big that they had manufacturing capacity to spare for others, enough that they could sell to others for less than what it would cost to start from scratch -- else why buy from them in the first place?

That nobody else is selling camera lenses with >200mm front objectives should also be a pretty big clue that there isn't some secret mystical source of such beasts that Canon went to. By way of comparison, Meade's biggest refractor is comparable to Canon's current Great Whites, and other manufacturers of consumer refractors have similar specs at the top end of their lineups. It's only when you get out of the consumer realm into scientific instruments that you find anything in the range of the Canon 1200...and those, by definition, aren't mass-produced. Indeed, they're made in similar quantities to the Canon 1200, and cost as much...hmmm....

Cheers,

Tokina 50-135mm f/2.8 DX

I had this lens in my bag but sold it after discovering that it did not offer anything the Sigma 50 150 2.8 (model I and II) could not do better. The Sigma is discontinued and replaced by the 50 150 OS which is in my eyes a joke as it is as big as the 70 200 OS.

All three lenses are soft.

The Sigma 50 150 front lense does not rotate, it does not extend while zooming and it is small and silent. Of course it is DC (digitally crippled) and EX (expensive). However as a 2nd hand lens it is usually a bargain.

The Tokina is sharper wide open at 135mm as the Sigma is at 150mm. Can't compare them at 135 mm as I never did test this.

I love the Tokina build philosophy, I like my 11-16 2.8 and my 20 year old 28 70 2.6 but:
Both lenses have no zoom creep but if you turn the Tokina upside down my lens makes the sound of a piston going through a cylinder and some rattling like a loose screw following shortly after.
The 50-135 autofocus has this acoustic resemblance of a BOSCH Accu drill. That does not diminish its optical quality but the Sigma scores much higher here in my personal preference with a silk smooth HSM implementation.

anyone had someone over their shoulder on a job?

I get this alot when I shoot event and wedding.For wedding,I will face their friends and relatives tried to take some shot with their cell phone or compact camera.While events,I will face those reporters from various of newspaper.
Often,I will let them have the shot 1st then I lift up my camera and raise my hand asking everyone look at me with strong and firm tone.Just 1 or 2 shot make sure everyone looking into the camera and I will leave the place while allowing someone else take the shot.
Then,I grab some candid with my 70-200 while they were been photographer by others.

Why NEW DSLR users have a tough time switching from P&S FAQ??

add the 40mm into the sub $500 lens this is top of the bang for buck chart IMO

Also

I'd like to add two other very common misconceptions people have

1) highest mega pickles is the best - this is often not the easiest thing to explain to newcomers, hell its impossible here (please dont derail this thread with infinite debate over QE and pixel density blah blah)
most common question from wedding guests / participants is how many mega pixels is that camera?
meanwhile i'm holding 2 or 3 different bodies

2) super zooms must be the best because they have the biggest range of numbers quite often newcomers dont understand the concept of aperture at all and therefore dont understand why that tamron 18-270 produces crap images compared to a 24-70 mk2
