Lighting / 72" umbrella... what to look for and what to avoid?
« on: December 03, 2014, 02:40:20 PM »
I know softies can give better catch lites, and umbrellas may not look as professional as studio lighting... but I'm cheap andi havea chance to get a 72 inch all white for $25 or a black back silver front for $35... (newer brand which can be a draw back) but once had newer stuff before and it doesn't prevent me from going back to that well.

So... any caveats,  72 is just unwieldy,  don't buy the all white,  don't buy the black/silver, set the 600ex rt to manual focal length and set it at...

I prefer not to throw away good money on something that seems like a good idea but isn't...

I contend it isn't,  but we have an emotional response to looking at poverty.

And I'm sure they use Photoshop too.   So I don't trust anything from the ad world. .. but it really annoys me when cheap camera use shots from pro gear... but I've complained about that before.

Maybe it is like a crumple zone in a car. .. the cap absorbs the energy of the fall thereby saving the lens from damage.   You are misinterpreting a design feature for a design flaw. ..

And yes that was all tongue in cheek.

I have been waiting for around 2 years to buy the Canon 70-200 F2.8L IS II and have seen it in the past drop to $1799. B&H and others have been selling it for $2149... What's going on!!!??!?!?!?!?!?
There is the 6th ave ebay deal. 

But if you go to canon price watch, you can get the lens for 1899 as well... so you are paying $100 more than your target price either way.  I'd say get it.

Lenses / Re: What distance to be at for AFMA
« on: November 29, 2014, 11:52:23 PM »
Near minimum focusing distance is where the dof is the thinnest... so I afma near mfd.  I assume if I am shooting a target 10x mfd then my dof will be much more significant, so a focus shift (assume I'm using that term correctly) may occur, but it should still be within my dof.

Not a good idea, for the reasons stated above.

I'm shooting my little rugrat... so I don't have much predictive capabilities when it comes to consistent distance from the camera she will be.

I test at 25x and 50x the focal length, so that's 10 and 20 meters.

Does the AFMA change with distance? In other words, if you set the AFMA at distance X, will it still be correct at distance 2*X?
 I ask because I do my AFMA with a DIY setup and I like to get closer to the target to take advantage of the thinner DOF. The thinner DOF makes it easier to see how much back or front focus there is.

per a dof calculator:

with full frame, 50mm, f/2.8, and 30 cm from subject...

Depth of field
Near limit    29.7 cm
Far limit    30.3 cm
Total    0.51 cm
 
In front of subject    0.25 cm   (50%)
Behind subject    0.26 cm   (50%)

but when you double the distance:

Depth of field
Near limit    58.9 cm
Far limit    61.1 cm
Total    2.24 cm
 
In front of subject    1.1 cm   (49%)
Behind subject    1.14 cm   (51%)

So double the distance and you wind up with a 4.39x the dof...

Per this page... it seems like we can get 5% back...

You mean the page that states, "Up to 5% rewards," which means anything from 0% to 5%?   ;)

True.  Don't forget that you can get an extra 1% cash back by going to Ebates dot com.  3% total isn't a ton, but 3% is still 3%.

speaking of gift cards, what happened to amazon, b&h, and adorama offering 1% back on a future purchase?  I liked being able to get a couple of bucks back and applying it to an accessory or whatever.

Hey, you're right. I just checked B&H and the 2% Rewards business has been removed from a couple of the lenses I was considering. Two percent off on a Big White is a lot of money, so they've effectively instituted a stealth price increase.

Per this page... it seems like we can get 5% back... but it says 2% on this page.

So who knows.. I guess it is only one some.

I was hoping we'd see a gift certificate for a 7D2 packaged with a 100-400L II, for say $200-300 off the list price, shipping by year's end. :P

I was hoping the 400 f/5.6 refurb was going to be available. At $910.00 !

*sigh*

I was looking at some 200mm f/2L lenses on ebay... but they went out of my price range...

Last year Adorama had a 6ft... maybe 7ft umbrella for $50... and I was hoping that shooting star would be seen again.  But no.  Also last year, Buydig via ebay was selling a 100L for $700ish after rebate... but again, not this year.  Having said that, I just sold my 2nd 100L, so I really should just stay out of the 100L business.

I was also hoping that Amazon would have a deal like they have had in past years... where you buy an entry level body with a kit lens and then they practically give you the 55-250 and the 75-300 for free.  But no. 

Having said that, I think I got in on the photo deal of the season... Kohls was selling a t5, kit lens, and a 75-300mm for 449 plus 6% tax, but then you could get 9 or 10% back using a cash back site, plus getting $15 kohl's cash for every $50 you spend, plus this yes 2 you points... so I bought the maximum allowed of 5. 

So I paid $2380, but I'm getting $675 in kohl's cash (the wife is going on a shopping spree), $112.50 in the yes to you points, and $202 in cash back... so my total for 5 bodies and 10 lenses my cost is $1390.50.

So I'm pretty psyched about that.

Even though i do not own a single sigma product,  I respect what they have done recently.   I personally want the 24-70 mm f2.  But I never thought the 24-105mm would be a winner. .. not for Canon. .. Sony & NIKON maybe.

Huh. ..

If you're renting, consider the 70-300IS.

The 70-300 is a bit soft from 200-300mm.  The 70-300 L maybe but the variable aperture at f5.6... losing 2 stops of light might be a big downer.
