Hello fellow Hogs.
This thread is aimed at Nikon shooters in particular. I would like to know if any Nikon shooters have compared the Sigma 150-550mm to the Tamron 150-600mm lens, which one they thought performed better and why.
I've done a search here on the hog and found Regi's comparison. The difference is he's shooting with a Canon and his Sigma is a 50-500mm lens. I'm really interested in Nikon comparison of the two.
I recently upgraded from the D3100 to the D7100.
I am in the market for a longer lens than my current Nikkor 70-300mm lens. My price range is between $800 - $1,000 dollars for better glass. I've found that bird photos (Bald Eagles & Hawks in particular) have become my fancy. I just can't get a good reach with the Nikkor 70-300mm lens.
Any suggestions and or comparisons welcome.
Thank you in advance.
Sunnybuck.

Whenever Costco posts an item for sale, in very small, tiny print, they post a message saying the item will be charged a sales tax at the original selling price of the item. This is legal in California, but I believe it is deceptive advertising.

I checked and Costco can do this, charge tax on the original price, but California law does NOT require them to.

I never buy high ticket items from Costco. Costco can never beat the prices offered by B&H Photo as far as I am concerned. Also my local Best Buy will match Costco's sale price and only charge me sales tax on the sale price. Screw Costco for their deceptive pricing.

I'm playing with some night-time photography and because at this point what I take photos of is not important, I set up the camera on my sundeck.
So often we see suggestions about locking the mirror, using a 2 second delay or using a remote shutter release to prevent vibration resulting in blurred photos.

I followed all these "rules" and still ended up with a blurred photo. The lens was stopped to f/16, exposure set to 60 seconds.
So, two areas of influence I had not counted on: We live less than 2 blocks from a busy highway, and while the shutter was open, I did hear one of those heavy transport trucks go by.
And our sundeck has a wooden floor, and I walked away from the camera while the shutter was open.
Both causing vibrations that travelled through the tripod to the camera, resulting in blurred photos.
Although I was still mighty proud of them, as the street- and house lights in the photos did have the star points I was after: 14 star points, 7 blades in the lens.
I'll be out there again to try different settings, in this case the heck with the vibrations ;-)
Next time I'm at our son's, where there is no heavy traffic and they have 10 acres of solid ground, I'll try as well!
