Help, Newbie to DSLR, Step by step to test my 15-85
Apr 11, 2012

Hi guys and gals, I finally got my new 60d with a 15-85 lens and a 70-300. I'm very new to all this stuff and have no idea how to test my copy, I had a P&S but wanted to go with something much better.

Before purchasing everything I asked a lot in this forum and most members suggested this lens. i read that there was a lot of owners getting bad copies, but I decided to give it a try anyway.

Now, my question is, is there any step by step instruction on how to test this lens?

I've heard allot about stops, F stops (f-6.5 etc) and I have no idea what people are talking about and I don't even know if this is something that can be adjusted while taking a picture.

So I need someone to guide me as I was a huge moron and an ignorant, which I am right now.

I just finished the 3rd chapter on the owners manual but haven't seen anything about this.

All help will be appreciated.

thanks in advance.

Hi
In spite of what you read it would be very unusual to get a bad copy.

The most likely problem would be what is called de-centering. You can test for that by taking a picture of a flat surface like a brick wall. The camera has to be square to the wall ie. not at an angle. De-centering will manifest as one corner or side out of focus while the center and other side are in focus.

Hmm, I'm not trying to put you down or anything nasty, but... if you're at the stage of, "I don't even know if this [f-stop] is something that can be adjusted while taking a picture", then I don't think you're ready to do any kind of lens testing.

I suggest you continue reading your manual (good on you for doing that!), and take many shots over a few weeks in Av mode using the centre AF point, then ask about lens testing.

You'll find lots of useful beginners' tips in the unofficial Rebel forum FAQ - http://snipurl.com/RebelFAQ

I understand your point and for me it doesn't sound nasty. I know is too much of a camera for me but I wanted something nice and most important I'm willing to learn all this stuff.
I'm just opening the link you provided.

Thanks for the link and suggestions.

Thanks, that's what I did this weekend :). Spent the week with my wife and 5 year old son and took some pics. But after spending almost $700 in my first lens, I would like to make sure I have a good copy. I have only 3 weeks for an exchange.

Thanks for the link wilbaw, I spent hours and hours last night and some more during the morning reading, that's a great article. From that article I open other links and found great information and also a huge and very useful glossary.
Going to spend sometime today printing ton of pages.

Thanks again, have a lot to learn about this type of camera, but I'm looking forward to it.

Yes, just shoot.

Everybody here is correct.

IMHO, even if you're seasoned, the best way to start out with a new lens is by taking pictures. The types you usually take. Close, far, indoors, outdoors. People, pets, flowers and trees.

Tests lead to more tests, and if you're doing them wrong you'll never be happy. The only time I suggest it is if you are sure there's a particular problem - then you can test for that.

Some folks are just plain old geeky with their equipment, I swear they buy to test and never take a single photo if it's not a chart or a wall.

If you look back on this forum within the past week I've posted gobs of links on how to test lenses. http://forums.dpreview.com/forums/read.asp?forum=1029&message=41170155 Somebody a bit further back looking to test their 15-85 as well.

No worries. I wrote it for you.

I'd also recommend you spend some time in the Rebel forum. There are many beginners as well as old hands there, and it's a lot friendlier than the 60D forum.

If you haven't noticed anything obvious, just forget about all the testing nonsense and have fun.

Quit worrying so much. If you are new, there are numerous opportunities to take blurry photos, etc. You'll never know until a couple of years from now. You've got a great kit (my kit). Have fun!
