Speedlites, Printers, Accessories / Re: Speedlite Tutorials?
« on: April 11, 2014, 11:13:43 AM »
I will do. Tomorrow, it is 11pm here. I am just reading the PhotoNotes article posted above. I'm guessing that the limited SS range setting on my 5D only applies when the flash is on, not all the time. It is in the Speedlite settings page. I will experiment. I certainly wouldn't want to neuter my available light Av settings.

I would use M mode but I find there are already too many settings to keep track of - see my 'needing a flash as all my photos have motion blur (because I set ISO to 100, not Auto)’  post at the beginning of this thread.

I think you also need to understand the fundamentals of an exposure.
You had motion blur because your shutter speed was too slow. Yes, raising the ISO will increase your shutter speed, but you NEED to be looking at all of your exposure data to understand why you are getting the results you are getting.

Aperture + shutter speed + ISO = exposure.

The great thing is you are using a digital camera- so you can look at the back of your screen and experiment!

Lenses / Re: Philosophical question about Sigma Lenses - Why?
« on: April 04, 2014, 10:34:51 AM »
"I have no opinion for nor against Sigma. I’m only interested in their original business model and how the founders of the company came to the conclusion of making lenses for other camera bodies out of pure academic curiosity."



3rd party accessories is a standard business practice across all consumer product categories. This is not unique to Sigma or the lens/ photography market.

Where there is a market, there will be competition to get a piece of the pie.

You have the products/ accessories from the OEM (Original Equipment Manufacturer) that set a price. Then 3rd party manufacturers can offer more "cost effective" alternatives, or fill holes in the market by offering unique products not offered by the OEM.

Sometimes a cheaper product isn't even inferior to the original, but they can undercut the MSRP because they have a smaller advertising/ marketing budget, inferior customer service, or are using "open market" parts, or they can operate on making a smaller margin, etc...

Sigma can also reduce the cost of production because they create products for multiple mounts. This increases their MOQ (minimum order quantity), which helps drive down manufacturing costs.

There is a lot more that goes into the cost of a product than just cost of goods.

Animal Kingdom / Re: What is this bird?

Appears to be a red-tailed hawk (although I'm viewing this on my iPhone).

Thanks!

Thanks brad-man! Yeah this is the only APS-c lens I own. My 7D was relegate to backup duty till this came out. Since the rest of my lenses are primes (besides my 70-200), when I want a zoom I now grab my 7D!

Also thanks for the compliments on the models. I'll give my wife the credit for our daughter :)

As someone who has not shot any video on my DSLRs, can someone explain to me the value in spending 4k on a 50mm zeiss lens to mount on a DSLR that is going to down sample the image to 2 mega pixels?

A few more.

Went to Disney last week. Only took my 7D and the 18-35. Was a fun trip!

Animal Kingdom / What is this bird?
« on: March 18, 2014, 10:54:15 PM »
This bird has been hanging out in the trees across  the street from my house (In New York), can anyone tell me what it is? I've never photographed birds before, but this guy is pretty cool (especially when soaring around), and is making me want to go out any get a longer lens!

Today I saw him fly by with a full squirrel, then land in a nearby tree and chow down for about an hour!

Photography Technique / Re: What could I do better?
« on: March 16, 2014, 09:28:17 PM »
I think the bigger problem is you were just unlucky with this opportunity. There is really nothing interesting about this image (besides it being a 2-headed deer), so it just reads as a "snapshot" type photo. I don't think it has anything to do with (1) you, (2) the camera or (3) the lens. The deer ran off before something worth shooting happened, and you couldn't direct them or pose them to your liking.

Sometimes there just isn't a shot.

EOS Bodies / Re: Calumet Photo Files Chapter 7 Bankruptcy
« on: March 14, 2014, 09:17:19 PM »
Sad news. As a New Yorker I routinely chose Calumet over B&H and Adorama because of their staff. There is just something about "taking a number" in Adorama, or the whole "system" at B&H that always feels a little cold to me. The guys at Calumet in NY were always helpful and smart. My office is also in the same building as theirs, so it will be extra sad to lose them. No more playing with lenses at lunch time...
