My wife, daughter and I watched all 7 episodes in 3 days. Excellent series. Thanks for the tip.

Is that the moon above the horizon

Thank you for the tips, replys and links.

Just curious, if you were going to drive around and take photos of Christmas lights at night. In manual mode what setting would you start with?

1. Is there an adapter that will let a sony lens fit on a Canon Rebel T6i camera?
2. On an old laptop I found a couple thumbnails of photos I took probably 15 to 18 years ago with a Sony Mavica camera. They come up as a .mix file. For the life of me I have not been able to get them to open. I have downloaded several applications that were supposed to open mix files but didn't work. Any thoughts or ideas.

Thank you.

[quote=Bill Emmett]I agree with all of the above answers to your question, but one item has been left out of the mix. It is the research and development costs. For example, Canon researches the type of glass to use in a lens, the actual patent costs, coatings, mechanics, electronics, and interface. Then the lens is produced as a test lens. All the components are tested in the lab, and then should the lens pass, it will be produced for testing in the wild, or distributed to Canon lens testers that are their field testers. After that test, any or all suggestions are evaluated and considered changes are made to the test lens. Then another "in the wild test" will begin. When the finished lens is decided on it is pre-production tested again in its final form for expected life span. Then the lens is released for final production. Again the production of the lens is watched closely for problems in the first production run. The pricing of the lens figures in all this testing, and evaluation of the final product. Then, there is advertising costs, and any further cost of testing against other companies products. As the lens is produced there will be minor tweaks in production that will be considered in the cost. Don't leave out the cost of new equipment to produce the lens.

Bill,
Thank you for that information. Of course those costs go into every lens made. The original question was why 2 lenses of what appears to be the same characteristics can have such a huge difference in price. Several of the posts above did a great job of explaining. Again thank you.

Nice reply fester. People like you (that apparently are smarter than everyone else and like to show it) are what keep forums like this interesting.

So, even though they have the same focal length the aperture size is what determines the size and amount of glass needed to manufacture. Am I understanding this correctly

What is it that can make one zoom lens or any lens so much more expensive than another lens of the same focal length.

I am looking for an easy way to locate duplicate photos on my pc. I did a google search and there are a lot of them out there. Does anyone have a suggestion on a good free app? I get irritated when I download what I thought was a free app and find out later that it was a trial app. I am even willing to pay for an app if it is reasonably priced.
Thank you.

You can have any item that you don't want going through the scanner hand checked by a TSA agent. Just let them know as you approach the scanner.

Thank you for the information. I don't do enough pp to warrant the monthly cost. Thus the reason to purchase the software. I will look into some of those that were mentioned.

Does anyone know if this software has the ability to work with layers?
Thank you.

Will GIMP process RAW image? When I try to put a photo in the GIMP processor the list of photos to choose from only shows the JPG version of the photos.
Thank you
