Are you KIDDING ME!?....Phil, look at these K10D shots!

Go to last post
cool beans!.....I cant believe what a hidden treasure this lens is!

Altho it looks like you have to get either the version 2 or 3 lens to really get a quality lens. I think the others are just ....ehhh.

Has anyone else found the version 1 or 2 on Ebay? What a score

What other 3rd party manual focus lenses would some of you recommend that arent Pentax.

You can better evaluate a cameras sharpness by looking at 900 pixel wide web images (with motion blur) rather then 100% crops?

Wow, you guys have better eyes then I do.

I have the Vivitar 75-205 M42 mount
The serial no. is 22601766
22 Kiron, manufactured by
6 Year of munufacture (not sure which decade, probably 76)
01 Week of manufacture….. (01 to 52)
766 Serial number

I found this info somewhere on a website, Vivitar had lenses made by different lens companies and my serial number shows the above info.

This lens was with my fathers Praktika film camera

I havn’t had a chance to try this lens on my K10 yet, only briefly to see that it works ok but I have a few M42 lenses and they work great. Have a look at this thread, with a depth of field test on some wine glasses

I only shoot with a camera
 
I have prime Vivitar Series 1 135 F2.3. It's very sweet M42 portret lens that I am still using on my DS. It huge though.

New Vivitars are not even close to it.
 
Lisa herself says that most of them were out of focus and that these were the acceptable ones. shooting action with a manual focus lens and that is what you get. if you think this demonstrates superior K10D AF by using a MF lens, you have really serious troubles.

HerbChong,

Your saying those pictures look soft??...........Im sorry but I just dont see it. Perhaps one or 2 of them, but most look very contrasty and sharp. Didnt the poster also mention that they were 2mpixel jpegs? Wouldn't that also have an effect on the possible sharpness...especially if some of them were cropped?

Im pretty impressed with what I've seen that the K10D can do
 
these are soft because of motion blur or focus errors. shooting sports with a slow manual focus zoom lens is not helpful and Lisa says so herself. at 900 pixels wide reduced from full frame, i don't see how anyone can make a claim of sharpness. i have been measuring my K10D against the *istD, D200, and D2X with a Tamron 90/2.8 Di Macro and RAW with default PPL settings, the K10D is about 15% less resolution than the D200, although significantly above the *istD.

Herb...
 
BTW, i do have the Tamron 90/2.8 Di in both Nikon and Pentax mounts. using ACR for RAW conversion shows that the K10D is about the same as the D200 within measurement error. since PPL does exactly what the in-camera JPG does, that means that the K10D JPGs out of the camera with default settings are about 15% less resolution than the D200 or the K10D in RAW.

Herb,

Do you own Pentax gear just so you can come to the Pentax forums and complain about how much better your Nikon gear is?

Here are the numbers from Phil's resolution tsts for the K10D and the D200:

Pentax K10D Horizontal LPH 2000 2300
Vertical LP 1800 2500

Nikon D200 Horizontal LPH 2100 2250
Vertical LPH 1700 2200

Based upon Phil's tests, I would guess that these cameras are as close to each other in resolution as Phil's ability to measure them.

So, you make a post claiming that the K10D has 15% less resolution than the D200, but the the big news is that you get softer jpegs out of the K10D? Go tell it on the mountain, as the saying goes......

i run Imatest Pro on my own cameras and lenses using the SFR resolution test module. when you can do the same, we can have a meaningful discussion.

Herb...
 
oh, and just because you have trouble reading past the second sentence of my post, i did say that the cameras had identical resolution. i can't help it if you can't read.

Herb...
 
Look, Herb wasn't comparing straight out of camera jpegs. He already said that this 15% loss applies when comparing jpegs from RAW - Pentax converted by PPL and Nikon by ACR. When both from ACR then there's no diff which corresponds to Phil's findings.

Herb,

Read this (as posted by you with no qualifiers in that post):

i have been measuring my K10D against the *istD, D200, and D2X with a Tamron 90/2.8 Di Macro and RAW with default PPL settings, the K10D is about 15% less resolution than the D200, although significantly above the *istD.

My reading skills are just fine. Perhaps your writing skills could use some improvement? Did you not state that the D200 is 15% more resolution than your K10D according to your tests? Did you not mean that?

Yes, you followed it up with another post with some nonsense that basically states the opposite of what you said above qualified by some old news about softer jpegs. No one here gives a tinkers dam about your Nikon D200.

Just in case you got lost somehow and cannot remember what forum you are posting in: this is the PENTAX forum. I do not know what you are trying to prove when you continually tell everyone on the PENTAX forum how superior your NIKON gear is, but perhaps you should go over to the NIKON forum and talk to actual NIKON owners about how good your NIKON gear is.

Ray
 
Holy Shmoly!......How did this thread turn into a Nikon vs Pentax pisssing contest??

I simply wanted to share the merits of this fine camera's capabilities in the right hands and the next thing you know, it just got all ugly in here??

Ray, I think you have a limited view on how people use these forums. A lot of people read these posts for information from actual users about the camera. Yes, that includes how they compare to other brands.

I am a Nikon D2H and D200 user who is considering getting a K10D to use with some of the innovative Pentax pancake lenses. I have been reading a lot of posts in the Pentax forum to see how K10D purchasers like their cameras, what problems exist and, yes, how they compare to other cameras. As a Nikon user considering a K10D purchase, I find Herb's insights, those of a skilled photographer and based on careful testing, to be very informative. I also think this information is more appropriate for the Pentax forum than the Nikon forum.

Now you can disagree with his opinions and leave it to others to judge which of you is doing a better job of testing. But I strongly disagree with your comments to the effect that he should not be posting in the Pentax forum and that nobody is interested in what he has to say.

Herb, if you're still reading this, thanks for sharing you experience with us.

Hang on a second tho.....In slight defense of Ray, while his response may have been a bit forward, Herb has teetered a bit on the edge of annoyance. He seems to be the first one to constantly chime in on any positive comment that is made about the Pentax K10D and spray his negative diagnostic benchmarks all over it.

Now I am totally one for observing test results and findings, but when someone seems to consistently, almost methodically innundate every positve K10D post with a contrasting view, it can get very disturbing...and can almost hint at ulterior motives as well....perhaps competing dslr employee?....stock holder?....disgruntled ex employee?....raving lunatic?

all of the above?
