Very tough to choose but this weeks winner is: noelcmn with A sea of roof tiles and moss. Great interpretation of the theme with the whole frame being filled with a repeating pattern of light, shadow, and colour. just a unique image that makes you look twice. Excellent job!
2nd place: SpecialK. Wow! great photo. I love the composition and simplicity with the railing, staggered drain holes(?), and the soft sea background.
3rd place: StephenHampshire. What a dreamy photo! Great use of colour and lines.
And a special thanks to all the other entries that made the decision of picking the top three such a tough job. Looking forward to next weeks challenge!!

Thanks Stephen for hosting last weeks photo challenge.
This weeks photo challenge is that you must complete this phrase using a photo: a sea of ...
You are open to interpret this in any way you choose.
The challenge closes on Tuesday,April 6th.
The fine print:
Every week, a new theme is picked and judged by the winner of the previous week.
1. Post ONE photo.
2. The photo must portray an interpretation of the theme.
3. Post your single picture in this thread and explain what motivated you to take the picture and/or how you feel it represents the weekly theme (especially if it's not obvious).
4. The challenge is interactive. Any response is welcome.
5. The judge will pick the WINNERS and choose one of them to be the judge for the next week.
6. This challenge runs for 7 days plus an additional day for the judge to choose the winners.
7. Any Pentax camera can be used.
8. Pictures can be from any time frame, not just within the week of the current theme.
9. In case the winner of a challenge is unable to become the judge for the next challenge, they will PM the #2 winner for that person to be the judge.
Here are a couple examples to get the challenge rolling.
1. A Sea of Yellow
2. A Sea of Humanity

FOR SALE:
1. Sigma EX 70-200mm f2.8 II Macro HSM APO DG. In excellent condition all around. Glass is mint and functions as it should. Comes with hood, front and rear lens caps, and tripod mounting collar. $380usd.
2. Sigma EX 50mm f1.4 EX DG HSM. Excellent condition, glass is perfect and functions as it should. Comes with both lens caps and original case. $240usd.
Why so Cheap?? In order to use auto-focus on the newest Pentax bodies(K-1, KP, ect) these lenses will need firmware updates. The lenses work perfectly on my K-5, K-5II and K-7. I assume they will also work perfectly on a K-3 and perhaps even the K-3II as well, however if you are interested in using them on said cameras or any other camera not mentioned, please do your research.
Payment: Paypal (United States) or E-mail money transfer (Canada)
Shipping: Buyer pays for shipping. I can ship using Canada Post, UPS, or FedEx. If you want to find out the shipping cost to your location use the shipping providers shipping cost calculator and the provided information. I will ship using whichever shipping provider and method you choose.

These are BIG lenses with fast and silent auto-focus and are best suited for event or sport photography ect, neither of which I do much of, therefore these lenses are in superb condition and hopefully they can go to somebody who will get more use out of them than I.

This is great stuff here. Seems all feel that the qualitative assessment of the reviewer takes precedent over the quantitative number assigned - the ratings are close enough to be useful but not perfect. I love this stuff because for the past few years i've been doing survey design, many times using a Likert Scale which is basically what the rating system is. A challenge is assessing whether or not the data collected from a Likert Scale is relevant enough to use that style of survey. I guess the real question here is do people see any value in collecting more precise numerical data, and the answer is no.

Ah shoot, my bad. I guess I should have searched harder for a similar thread. Just thought it might be a stimulating conversation had it not taken place already.
anyhow I guess that's one vote for for the review section being perfect as is if one applies a simple mathematical equation:D

I'm sure everyone can agree that the lens review section of this forum is one of the most useful tools to us Pentax user. I have used the resource for years to find information on lenses and it has been invaluable in regards to choosing the right lenses for my desired photography kit ... thank you PentaxForums!!
So I decided to begin posting reviews of my most used lenses, but only lenses that I have had years of experience using, as well as having had experienced using other lenses of a similar type to compare with - this seems to be the only fair way to write a review. The first few reviews that I wrote were definitely influenced by the rating that the lens was already given by previous reviewers, however the more I thought about it the more wrong it seemed. When filling out the required "post a review" form I noticed that the scale used is out of 10, but 5 is rated as "good". So according to the reviews, nearly every lens Pentax has made falls between "good" and "excellent" - most closer to excellent.
Now don't get me wrong, I'm a loyal user and lover of Pentax lenses for umpteen years, but do the reviews seemed way too skewed to the right to be accurate? Does it seem to anybody else that 10's are given out way too freely? Should 10's not be reserved for only the best of the best?
I have used a few real stinkers, but according to the rating they have they are above "good". The FA 28-90 f3.5-5.6 for example was one of the most horrendous pieces of garbage I've ever put on my camera but I ended up rating it 5. Why? because I felt that it was in line with the other reviews. But a 5 rating indicates a "good" lens. If anybody ever asked me if this was a good lens, without hesitation I'd say NO. That was a mistake on my part and I will not rate lenses this way in the future.
I believe the lens ratings would be more accurate if there were no option to give the lens an overall rating, and the overall rating was instead an average of the individual rating categories. I noticed that many lenses get rated 10 even though the reviewer gives low values in the individual categories. This makes no sense to me. How can a lens be described as "soft" and have a "cheap plastic build" with a rating of 7 for aberrations, 8 for sharpness, 9 for bokeh, autofocus, and handling, and a 10 for value end up with an overall rating of 10? If the categorical ratings were averaged out it would come in as an 8.6 rating. Round it up to 9 and it would be more accurate than the given 10.
I feel that many cheap yet decent performing lenses get a rating way too high. It's as if value trumps all other categories and it doesn't matter if the lens has a shoddy build and poor auto-focus because it was only $20 ... 10/10. I also see the same thing on very expensive lenses. The reviewer will name a bunch of things that they really dislike about the lens yet give a 10/10 overall. Where's the logic?
But since lens reviews are completely subjective who am I to argue;)
I would love to hear what other forum members think on the subject and I believe it would be a good discussion topic.
Do you think there could be changes made to the review section to make it more accurate? Or perhaps you believe that since reviews are so subjective the review section is perfect as is? Chime in!!

I just traded in a minty copy of this lens to B&H a couple of weeks ago. I believe it is still up for sale as I write this. If you hurry I'm sure you could snag it.... but it hurts to see the price that they are asking for it after the meager trade in price they gave me:( Good lens though. A little too big for my taste but considering the line-up of Sigmas you have you certainly wont be bothered by that.

Yes, it looks stuck closed to me. In the second picture, is the camera turned on? If it is then it is stuck closed. Try gently opening it with your finger, careful not to touch the sensor behind the shutter. Don't force it though

Sounds to me like your shutter is sticking closed. This happens to my K-01 intermittently - can never predict when. To "un-stick" it I have to turn the camera off and on again. Perhaps you are experiencing the same problem. To check this, take the lens off and turn on the camera. The shutter should open so you can see the sensor ... if it doesn't it is sticking closed.
