Metering issues?
Posted By marlon
Replies: 27

If I had metering issues with any pentax, I would not have upgraded to yet another pentax. The only times metering fails me, is when I am being an idiot. The K20/K200's seem to be metering really darn well compared to "some others" Ive played with in the shops too, so I don't know what that dude mentioned by the OP is on...

Also judging by the amounts of posts by the OP and other thread/posts, I am personally inclined to just ignore this and go on. I can smell it a mile away.

Glad you followed your own gut-feel, it helps. People are different, so you got something else, while the rest of them got one thing :)

Hehe, if you could capture the bike blurfree, but still have the wheel blur (perhaps some panning), damn, what a shot that would make!

I have a question. In each of the bokeh light dots, there's a little distortion, and for each dot they look similiar. What is that, why does that happen?

I like the visible bokeh'd branches in the center back. It adds to the image's naturality, a complete blacked out bg would have made for a very "modelled" shot.

Agreed. Turning it on, and powering up the circuits is the worst thing to do.
A friend dropped his in saltwater, and out of frustration, decided to try and save it from corrosion by taking out the battery and dip/drowning it in fresh water. He let it dry, and everything was ok, except the lens :)

Two Sigmas, Macro, how now brown cow?

Ok guys, I see it's ok to post about third party lenses, so let me hit it off.
I am tired of struggling with add on convertor lenses to get 1:1 macro's done.

I am looking at two of the Sigma Macro's:
The 105mm ->Sigma - Lenses

and the 70mm ->Sigma - Lenses

For the 70mm they mention that it is usable as a normal lens to, focussing to inifnity etc, but not for 105mm, does this mean the 105 is MACRO only?

Also, for those owning one of these, please share some opinions, I am really strapped for budget here, and Im confused, and not sure why the 70 is $100 more expensive than the 105mm.

I hope that someone could provide some input on this matter.

Regards
Marlon

Pentax K20D vs Canon 40D

My reason for the choosing of said, K20D, was simply because I am sold on Pentax's service and reliability in the past, and because everything else felt like a bbgun in my hands. CLick click.
I would agree that the only real upside on the 40 is the 5 fps. COnsider the technicalities too, SR, sensor dynamics etc.
But you should try both, to see what feels best,not what the head of marketing wants you to have :)

hehe, unfortunately it was already on a tripod (with 2 s delay).
I think that's the best it can do or perhaps, Im not seeing the focus very well (as usual) through the viewfinder. :)

I like it as it is, I like the first building on the right, but Gary has a point, taking out the first light could do a bit for compressing the scene a bit. This is a very nice exposure !

I really couldn't find an "M42 club" type forum, every search I do says "nothing found", so I created a new one, forgive me.

Anyway, I got this battle scarred, used up and bruised Hanimar 135mm M42 lens from a friend recently. Last night I put on the pentax adaptor, went out on to the balcony and decided to try it out a bit.

For it's condition, the amount of dust inside, the scratches and the amount of times it seems to have fallen down 500 stairs, I got suprisingly good focus and sharpness (not the best, but not bad).

I downsized it and compressed jpg to around 85% so bare with the artifacts.

So, to whom it may concern, here's a photo Ive done last night (long exposure on my k20d), and a photo of the lens itself following...

(edit: image too wide, linking to it)

And the lens looks like this:

What?
What about setting the NR setting to None? I could have sworn theres a "None, Weak, Weakest, Strong" as well as the "auto" or "on" option.

I have set mine to None (or whatever the minimum/off was called).

Maybe Im confused, but I know what I saw.

the front element is at the base of the hood, it doesn't move out :)
Internally they move, but this doesn't matter, it's about the last piece of open glass, which is the front element. Ive never seen them move out of the hood before.

Guys, you are saying that taking the lenscaps off are hard? Why not just get "inner pinch" caps?

grainy B&W - not from high ISO ?

This is a good question.
Im hunting the perfect "feel" ISO fir b&w conversions myself. I find that my body set on "strong" NR with around ISO 800 gives me the feel I like for facial shots. I don't apply NR during PP though.
Think I will follow this thread for a while, see what pops up

Hi

Thanks to all who replied, Peter Zack, Marc, and those on the same line of thought appears to be correct. It seems like my AF was fooled indeed, I didn't know how big the af sensing areas were, I had the lens at the extremes and it was a damn hot day, so there was alot of discomfort adding to the experience (making wierd angle poses harder than it should be).

I played around last night, doing AF and MF ons various objects and cars speeding past etc, and had no issues.

So between the above issues and my inexperience, I found the problem. Im too scared to use more ISO, but will learn to do so.

I feel much better now, thanks guys.

PS: axl, I focussed with the middle af area on one of the conifer trees(where it meets the sky). Seems this Sigma EX is pretty soft at that aperture and 18mm :)

tomtor & jmc thanks.

Tom, it seems what you say makes sense. I might be overly critical, and should have used manual focus on difficult images like #1.

I did indeed use a hood, but must confess I have a seriously cheap Kenko UV filter on my lenses (same type on both). I also realized that with the opened up to 4.0 this might also have affected the sharpness.
I agree that the contrast is low, after I read your explanation it started to make sense.

I also searched the forums now on the center AF point being bigger than I'd expect. Didn't know that.
As for #2, ive never had much luck focussing on leafy stuff like trees, very hard with the viewfinder being so small :)

Thanks again for the input

Hi folks,

I spent 5 hours in blazing heat yesterday, just to come home once again, and find that about 4 of the 400 photos I took are usable.

Im not sure why this happens, and Im not sure if it's camera shake or OOF. Maybe you could have a look at these three 100% crops (no editing done) and help me?

Note that I used spot AF on the main subject in each of these.

Im finding it hard to believe that it is camera shake, because as you will see, in most cases my shutter speed was many times more than the FL/SS rule expects it to be.

On the other hand, I trusted AF.s mode the whole day, but AF never failed me before, so why would it this time?

I used two sigma lenses all day (EX DC 18-50 and 70-300 APO) and both showed the same results.

One last thing to note, I used the ISO D-range feature with ISO set to 200. Could this be it? What does this exactly do?

Hope to hear from someone soon :)

Appreciated, regards
Marlon

1/2000 f/4.0 50mm ISO 200 (D-range)


1/500 f/4.0 18mm ISO 200 (D-range)

Sounds like a plan, but not one im comfortable doing, just like I don't like using spanners as hammers.
Maybe someone else could advise on the wear/tear and feasibility of this?
