New Pentax-M 50mm 1.7: some testshots
Posted By: Rense, 01-13-2009, 12:10 PM

Today my newest "asset" arrived... The 50mm 1.7 manual, won on eBay. The first thing hitting my eye to be photographed were my wifes Phalaenopsis orchids in front of the dark window. Both pictures with lens wide open....

Nice Orchid shots. Maybe a bit of white balance adjustment would highlight the subject more.
Then again, perhaps you are wanting to test the capabilities of your new lens without PP.

Nice shots for low light.

Thank you Bruce. You're right, WB adjustment brightens the flowers, I already proved that. But these shots came just out of the box, although the last one is cropped.

Rense,

I love this lens too. It stays on my 2nd body all the time. (If your body looked as bad as mine, you'd have a second body too! Yuk Yuk).

Nice capptures.

I do disagree that the color balance is the problem here though. These images are somewhat under-exposed by nearly a full stop. On the close up image the white of the flower will bias the meter... therefore tell you to stop down. In reality you need to open up a little. Run some tests and get familiar with the quirks of white or dark objects.

Steve agrees with Stephen...both are at least 1 stop underexposed. Exposure is a challenge with Pentax-M lenses. There is a certain amount of trial and error involved. The histogram is your best friend here. On a subject like this, if you don't see a significant bump on the far right, you are not giving it enough light.

My experience with my M 50/1.7 is that there is about 1.5 stop underexposure at f/1.7 evening out by about f/4-f/5.6.

Stephen, Steve, this is why I like this forum! I really appreciate your comments and tips. So, after some playing with Lightroom, I agree with you both. Adjusting exposure just a little makes these photos very much better!

Thanks again for your advises. I will play with it a little "in real life" to get aquainted with this kind of situations. Like the learning , this is why I joined you all.....
