My K-m Olive Vs K-x Navy (ISO Measurbation)



Well, it's also about CCD Vs CMOS and 10.2 Vs 12.4 MPs! ;-)

The shootout was carried out at almost the same time, for the same target at the same distance, with the same lighting condition (diffused daylight indoor) and using the same lens. The cameras were mounted on a sturdy tripod, shutter fired with an IR remote controller.

Both cameras were set to use the Exactly the "Same" available Pentax Settings; Lens used is my early Japanese production FA 43/1.9 Limited (Effective Film Focal/AOV: 66.0 mm); Av Exposure Mode at f/5.6 (should be the sharpest aperture for this lens); Single AF Mode Focusing on the Centre; Finest JPEG, "Bright" Custom Image Mode, Default Factory Settings at the Green Dots, Factory Default "Sharpness" (Not "Fine Sharpness"), Auto White Balance, Evaluative Metering, No Exposure Compensation, SR Off (as Remote Controller was Used), Shadow Compensation and DR Expansion Off, High ISO NR Starting from ISO 800 and Up at Medium (Factory Default) for the K-x and "Weak" (actually also the Middle Setting) was Selected for the K-m;

(Well, I think this test is much meaningful enough for setting up the cameras like that! No more "Apple to Orange" argument?! ;-D)

Last but not least, and of course, full EXIF data are preserved:-

1. Click on any of the Thumbnails will download
Large Files in size near 12MPs each;
2. If you still want to view original un-retouched full sized sample, see them here (under the "download" option, select "high res image").

Yet once again, as usual, Happy and Endless Measurbation!

As expected, K-x at ISO 3200 is a tiny bit worse than K-m at ISO 800. Pentax did a good job here.

The nice thing about K-x' ISO 12800 is that the image is still usable. Image looks printed with sub-dye printer (CP3020DAU in my case) considerably better than it looks on monitor. Therefore the noise is very "friendly"... HR, are you becoming a fan-boy with your new "toy" what deserves plenty respect? :o) Fun shootout, thanks much! BTW, your little "animals" look fun as well....

Well, I am actually a die-hard stupid fanboy who always loves the brand blindly and is much devoted, don't you know? ;-)

And, yes, the birds (well, birds are animals, right? ;->) are cutie, although they can look somehow somehow stupid, just like me! ;-D
Interesting there are some texture in the purple part shown in the k-m results, but not k-x.
are the texture just moire effects or real?

These are moires. The K-x pics show the real texture.

That means the AA filter in "family camera" K-x works like a pro! Nice to know the comparison...

And RH, being hooked on cameras/lenses and having love for animals (including stuffed like your birds) makes you a human with intelligent worthwhile hobby/interest. Much, much more than what brain dead morons in bars or those what don't mind to blow others up can claim! Great blog you have here, indeed...
:-) Thanks, Guy!
K-x has very weak AA filter.
RiceHigh 您好,
我是Steven,首先恭喜您入手k-x好機啊!!
這台除了沒有對焦紅點,其它都好!

有件事想請教您,一月底我可能會前往澳門二天,
除了走走古蹟景點之外,也想逛逛相機店(二手),但不知澳門哪裡有相機街可逛.......
請問您知不知道澳門的相機店鋪哪裡較集中或有名...,
若您知道,還請您提供一些資訊,謝謝~~

Steven, 您好!

我上星期剛剛去完澳門兩天, 帶了 K-x 連 FA 31 和 Kit 鏡去, 總括來說這部機不錯, 我亦相信它是賓得歷來所生產數碼單鏡機中最好。

至於相機店, 我見新馬路頭尾附近有幾間, 不是太集中, 亦可能要花點時間去找, 以前我曾經逛過一兩間, 基本上哪些店舖沒有特別專門賣新品或二手, 而係兩樣皆有, 規模亦不大。

至於古蹟景點, 我介紹可以乘松山纜車上東望洋山燈塔, 這裡還有一個小教堂和古炮, 附近有二次大戰時防空洞入口(全部不能內進), 纜車山腳站在「二龍喉公園」, 逢星期一停開, 不過行上去亦不太高和遠, 去完燈塔可再環山行一周, 可鳥瞰整個澳門, 慢行需時大約一小時。

夜晚可去氹仔威尼斯人酒店影夜景, 晴天很美, 再去裡面大運河商場逛逛, 影相不錯, 女仕可買點東西, 平貴名不名牌都有, 又有不同類型的食店、雪糕店和咖啡店等, 行累了可在哪些地方休息一下再走。

大運河有威尼斯小艇收費可乘搭, 連船"夫", 他/她會與你閒聊和唱意大利歌曲給你聽, 價錢不便宜, 但感覺很不錯。我年前去坐過, 當時那位船"夫"是一位女留學生, 她說給我聽她和男朋友都在這所酒店兼職, 抓一點外快。

如果你喜歡手錶, 在威尼斯人對面有"新濠天地"二樓商場全層都是鐘錶首飾店, 很集中, 地面賭場入口有"天幕表演”美人魚秀, 不是很特別, 但亦有不少人觀賞和拍照留念。

我在將會發佈的 K-x Review 將會有不少 Sample 照片, 大部份會是這次澳門旅程在以上地方拍攝的。

最後, 祝旅途愉快!
真是感謝RiceHigh您熱心且詳細的提供資訊,
您提到的那小教堂與古炮正是我想去走的景點呢!!
再次感謝~~
不用客氣! ~
K-x's ISO 1600 is really cool. Low noise and good details.
I'd say ISO3200 is rather good too...It's unbelievable
When is your Kx review coming out, rice?

I don't know actually :-), just too busy these days and indeed I have no time to write even one word for the review this week. Hopefully I shall have the time and more determination to complete it soonest! ;-)
It would just be so important. No other reviewer knows the previous Pentax problems so intimately like you. AF, yellow light, banding etc...
