K100DS, 10-20 @ 20mm, 1/250th @ f/16

Doesn't always have to be set at 10mm!

Having shot with that very lens for a couple of years I can tell you it is not typical. I was always impressed with how well the 10-20 4-5.6 controlled flare, particularly when you consider the focal range. I am not someone to compose a shot with the Sun as the subject, but never had problems with flare in my shooting with this lens. That does not mean it will not flare--you must be mindful with the composition.

the composition is the key.. at certain angle toward sun this lens creates flare which more like hot spot in picture -same like its brother 8-16-

I think many folks shoot with a uv filter on this lens to protect the exposed element. I do use a filter and have seen this droplet kind of flare infrequently. Supposedly filters can contribute to flare problems but i have no before and after comparison shots.

Mind to start it (before and after comparison shots)?

Love the shots..

The first one seems like a great place to explore this lens.. prefer at blue/golden hours.

Yes you're right.. at 10mm the great mountain will look much smaller. Nice pic

Great shot! I couldn't help but noticing that your sensor needs cleaning, though. Also, I think it would be even better with a tighter cropping of the grey at the top.

Yes, wonderful shot rob1234! I think Ikarus is right about the cropping - maybe make the edge of the clouds into a line from the upper left corner, pointing down towards the mountain?

calicojack · 07-12-2011, 01:14 PM

I think that leading line (edge of the clouds) and the "blue wedge" are important to the composition of this shot. Excellent.
P.S. I didn't even notice the dust bunnies until Ikarus mentioned it.

Many thanks for everyone's comments. Yep, had a dirty sensor for the whole trip, I never got round to PP-ing them out...

Here's a crop (about a 40mm (APS-C) FOV I'd guess). The old K100DS still makes some good pics!

Not half bad for fireworks either- especially when you are right under them! (10mm)

Jeff Bennett · 07-12-2011, 07:32 PM

It became painfully apparent to me that the on camera flash of my K-R will not work with this lens. My wife was already surprised to see the new purchase when I showed up to take real estate pics of our new listing. I didn't have the heart to run home and get the two af360 flashes she doesn't know about either. :-) Now to try to figure out how to either lighten the shadows of the lens cast by the on board flash or really lighten up the pics taken without flash.

There are several diffusers on Amazon for on-camera flash. I use this one - one of the guys in the macro clubs turned me on to it. It works for diffusing around the 10-20, too >

It's a good pic.. very tricky to use 10mm to this kind of subject, the fireworks will look much smaller and less appealing.

I never see an UWA lens that works fine with internal flash.. jstevewhite has solved the problem

Jeff Bennett · 07-18-2011, 06:05 PM

I actually used a little puffer diffuser for another house and it worked ok. No huge 10-20 shaped shadow in the middle anyway.

Thanks- This is a great spot to watch from, about 100 ft from where they light them off. 10mm was my only choice to cover the area they were exploding in!

I like the way you can get wild angles in rooms by tilting the camera a little bit.

I find it's sometimes hard to hold the camera level and square enough to avoid odd angles.
