From my point of view this image is more complicated, than a photo of young goat. Because, two yellow flowers on the right and top are looking similar to the eyes of invisible monster)

Not quite as sharp as I'd like--I'm blaming the mat of poison ivy I had to stand in--but a neat wildflower, nonetheless.:)

Interesting answers in this post. I can honestly say that I have never used the green button. I guess it is the old-time film shooter in me but I always set my own settings. The green button is just something to avoid touching accidentally. :lol:

K-3, DA*60-250 + HD 1.4 TC, ƒ6.3, average speed around 1/400

I've been seeing a few more Redpolls every day...during the Park Winter Bird count apparently they only saw two. I've had two hanging around for a while. Today, I had an actual flock of 15 plus birds. I noticed they were coming to a spot where other birds were dropping seed from perches higher up in the tree. I thought to myself, "Self, they like that spot." So I tossed a handful of see there.

First on the scene are of course the Chickadees. If the Chickadees don't like it, it's not suitable for man nor beast.



Then the scout.... typical finch behaviour, I don't know if they take turns being the scout of if there one designated scout, but there's always "the scout...". Redpolls, Grosbeaks, Purple Finches , whatever kind of finches, they all appoint a scout.



hmmm... look at all this food.. best call the others...



All the sudden the flock descends from their hiding spots among the nearby trees.



At this point there were probably 15 on the ground.


All the sudden, an alarm sounds, they all disappear, you can wait as long as you want, all you're going to see is more Chickadees.

18-135 Focus losses when zoom out

I really dislike the feel of the 18-135 for manual focus. It is a great lens and I use it all the time in AF but detest it for manual focus.

18-135 Focus losses when zoom out

Ahhhh - sorry now I understand. Manual focus primary use lenses are different. I LOVE them but not with my K50. The stock focusing screen stinks for manual focus and I still haven't found LiveView to be consistently better than focus confirmation even with focus peaking. Frankly I guess at some future point I need to try one of the split prism focusing screens but the hassles of that setup are enough to keep me from just jumping in feet first.

For great feeling manual focus I'm not sure what current model zooms to recommend. The SDM based DA* lenses have an odd feeling to them when manually focused - the lack of a positive stop at either end is one of the things that makes me a little cool towards using them in full time manual mode. The older FA lenses are so so but I think the K and A series might be your best bet. Best of all they are generally cheaper (not all models) than the equivalent DA/DA* models.

The DA 18-135 is not a Parafocal lens. It does not maintain focus across the zoom range you have to refocus at different zoom ranges.

Which one?

Just be careful with the 45 CT-1; serial numbers below 534000 are not safe for digital cameras. You need something like a Wein safe-sync.

If you don't have the original battery, you can still get the battery holder and put alkalines in.

AF or MF?

If you want MF and can find one, a vivitar series 1 70-210 F3.5 ( first version of the lens with constant aperture). Sharp, fast easy to use as it is a single ring push pull zoom, reliable and quick to focus with 180 degree throw from minimum to infinity, but enough throw to be accurate. It is a true zoom, so bulling straight back does not change focus, and it can do 1:2.2 macro with no adaptors. They usually go cheap,mount are very high quality

Ok, so in reading this,myounwant to use flash, so, any lens must be KA or later to use your flash , so strike the series one lens I suggested,

One thing to note, you are wrong about CA. With the right post processing tools Lateral CA can be easily fixed in post processing, as can purple finding, but sharpness cannot.

Also note that edge sharpness and lateral CA go hand in hand. I did a series of posts looking at a lens that had very bad lateral CA. Pentax photo lab , Photoshop, and many other programs and photo shop compatible plug ins have lateral CA correction which is done by rescaling the three Color layers. Lateral CA is the result of slightly different magnification at different wavelengths, and if your CA correction works by rescaling the color layers (by changing the magnification of each) you can almost completely eliminate it, and the resulting improvement in edge sharpness is quite noticible
