Hi

Here are some shots I took recently using the DA 50-200mm. Not sure if these photos are stellar in terms of sharpness as I am still inexperienced in photography.

Also, are these photos underexposed or overexposed? How would I improve them?

Thanks

Axl - I don't have both lenses, sorry.

Raider - Exposures are fine but last shot is a bit busy so the subject gets a little lost.

Thanks for the compliment.

How do I tell if I am under or overexposed? How do I tell when I am actually doing the photo-shooting? From the LCD display it is almost impossible to conclude anything...

Try using a histogram. It is usually coupled with the info button on the back of most digital cameras. You can either view a photo on the LCD with the histogram showing, etc.

The histogram will tell you how many pixels you have that are either too dark (left side) or too light (right side). If you can get a histogram in the center then that is usually good exposure...but this depends on what your trying to achieve. Histograms that are touching either side will indicate very dark shadows (possible loss of detail) to blown highlights (definite loss of detail).

here is a link with a lot more detailed information. I always use the histogram feature of any camera. I find it truly indispensable as you can't really tell anything looking on the back LCD of any camera.

What exactly does the "Di" of "Tamron 28-200 Di" mean?

I have a Tamron 28-200mm XR (IF) F/3.8-5.6 if this is the same or similar lens? I could provide sample shots if you give me an idea of the kind of thing you want.

You are welcome.

Tamron''s Di stands for "Digital Integrated".

I believe this means it has the optimized lens coatings for digital cameras, but can still be used on a 35mm camera.

My personal observation after using the DA50-200 for a while is that it really need a bright daylight to capture things in good focus. In shady and cloudy day, the slow speed of the lens is quite bad.

I would love to get a 50-200/f2.8 if such lens exist

yes it is the same lens, and the Di stands for digitaly optimised, that means this lens is suitable for both digital and film cameras..

I have that lens too, so thanx but I don't need sample pics, I was just interested how it compares with DA 50-200. Because I've seen crazy offer on internet for the samsung - schneider kreunzach version of the lens. But is it worth having it once I have this Tamron???
