Lense question

3 posts in this topic

They say there are no stupid questions but this may be one. Keep in mind I had a photography course in college and that was a mighty long time ago.

I have a Nikon D40 which I like. I purcharsed the Tamron 70-300 which I like as well. It does have the AF feature but I rarely use it. It is a telephoto macro zoom lense. Can someone tell me more about the " macro" part of this lense. My understanding of a Macro Lense is one that you take close up pictures with, like within inches....This does not seem to be the case with this lense. Help me understand the Macro feature on this lense please.

icewoman, it's been a long time since I shot that lens and I don't own one anymore, so I'm going from memory.

But in general, a macro lens is simply a lens that is typical in all ways except its ability to focus closer than other lenses. So with your Tamron 70-300 in non-macro mode, the closest you can focus is about six feet. In macro mode (which your lens will only go into if it's zoomed to 180-300mm) you can focus to about three feet. Being able to cut your focus distance in half makes the subject much larger in the frame, thus the description "macro."

It's not a true macro lens because it won't focus ultraclose, but it focuses a lot closer than 70-300 zooms that aren't labeled "macro." A true macro lens will allow you focus with your front lens element only inches from the subject.

Hope that helps!

Thank you. That is the line of thought that I had. Tonight I will experiment with taking the same picture in Macro mode and not and comparing the two. It seemed that I got a better picture and was able to crop and enlarge to a greater degree when I did not have the lense at full zoom, I am thinking that may change if I use the Macro setting>

Next will be taking the camera off " automatic" and setting my own settings.

    •   "We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon.  I am thankful for that."   Thanks for making my nite.  
    • Also woodpeckers beat on stuff to mark their territory.   I am pretty sure that there aren't any bugs on my metal downspouts.
    • You will often discover that birds are picking very small insects from decks and other woodwork around your house;  they do the same with trees and any other structure that might hold the bugs. We see them often on our decks and they usually pick a little bit and then move on,  perhaps just checking to see if there is anything edible there. These rascals also love hummingbird or oriole nectar, sunflower seeds and of course suet in winter. We have discovered  many species that will head straight for the nectar for orioles or hummingbirds and also plunge their beaks eagerly into the grape jam bowls orioles love. Birds will eat a greater variety than you might think. We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon.  I am thankful for that.
    • And pretty soon there'll be little chinese restaurants springing up everywhere...
    • I use the ball of aluminum foil, too. Works well.
    • lay them in the grass over night and wipe off in the morning.  the dew soaks in if it's moist out.  other wise lay them out and place wet towels over them for awhile..
    • What do you have against Japanese Beetles?   Diversity is good.   We need all nationalities of beetles.  Even VW beetles.   Asian Lady Beetles, everything.  All nationality and gender identity beetles. 
    • Tysons chicken tender, Top sirloin steak, pork chop, burgers seasoned to taste - crispy crowns, tutor tots, fries - beer batter shore lunch Walleye, Crappie all better than deep fryer, oven or gas grill. Just do potato first & keep hot in oven at 250. Even Spam is better than pan fryed but if your under 40 you may not have a clue about Spam.
    • Yes spray it, or wipe it down with an oiled paper towel before you use it.  I use a little ball of aluminum foil to scrub them after the cook, but while they are still warm. They make disposable grill topper grates that are handy too when you are cooking something that is going to be really messy.
