Pentax smc DA Fish-Eye 10-17mm f/3.5-4.5 ED (IF)

	APS-C大小的影像可產生APS-C大小影像的鏡頭只屬數碼屬性，它們不可使用於比APS-C 格式更大的影像接收器，也不適用於菲林相機。無超聲波自動對焦一般來說，超聲波對焦鏡頭比傳統對焦鏡頭靜和快。使用了一個或更多的低散光度鏡頭元素低散光度鏡頭元素能減低彩色的色差。不穩定影像穩定器能減低手震時產生的模糊影像，特別在長焦距或陰暗情況下。根據倒數的定律，影像穩定化比無影像穩定鏡頭能有1到3個光圈優點。金屬接腳平價鏡頭通常會使用塑膠接腳，而較昂貴的專業的鏡頭會使用金屬接腳。一般來說，金屬接腳會比較耐用的及當鏡頭改變很多。當相機主要使用一個鏡頭，接腳物料並不是很重要。內置對焦內置對焦鏡頭不會因設定焦點而改變其大小。固定前鏡頭固定前鏡頭在變焦及/或對焦時不會轉動，故可容許攝影師用花瓣狀遮光罩，固定前鏡頭能更容易利用極化濾鏡。

Impressive, but watch out for that front element

23 November 2006

Sometimes you just need to go to the extreme - in this case it is really wide angle. In my old Canon film-camera days, I had the 15mm 2.8 fisheye which was an even bigger chunk of glass because of its speed.

Now that I have gone to the Pentax K100D camera, I was pleasantly surprised to see this 10-17mm lens was available. I was even happier because unlike the Canon lens, the Pentax is a zoom, so that not every shot has to be the distorted wide angle that you think of when you hear "fisheye". The lens goes out to the equivalent of about 26mm on a 35mm format, which is a very useful focal length as well.

The lens also allows manually tweaking the focus while in the auto-focus mode - something my 2 Sigma lenses warn against.

The only drawbacks to the lens that I see are that you can not mount a filter and the curved front element is exposed (same for the Canon). So, just use a little caution. And, unlike the old Canon, there are no rear filters either. Finally, for those who like to manually adjust the aperture ring - there isn't one. It's all set through the camera :-)

I could go on about the lens, but as they say, a picture is worth a thousand words, so I've posted a few photos in the Amazon collection.

Digital Fisheye for Pentax

22 February 2007

Every bit as advertised. A most unusual lense. It takes a while getting use to the lack of an apature ring but the lense is everybit worth it. If you are in a small room and need to take in the whole room this is the lense for you. The Lense is as sharp as all of the other pentax lenses that I have and the depth of field is tremendous.

Fun Lens to Have

16 August 2008

Have owned this lens since December 2007 and have had a lot of fun with it. At 17mm, it functions like a conventional wide angle lens, but at 10mm it is truly a fish-eye. The flexibility cannot be beat! Image quality is excellent (color rendition and sharpness). It can produce some interesting perpectives once you learn how to exploit its characteristics.

The lens surface extends (bulges out) beyond the front rim of the lens which can expose it more than a conventional lens. However, Pentax claims that it has a special coating which is supposed to resist scratches. I am ultra careful and choose not to test the strenght of the coating!! The lens cap is a slip-on type vs. a clip-on type. The lens is a tad heavy, but solidy built.

The more I use this lens, the more pleased I am that I purchased it.

Versatile, adds creative dimensions

24 July 2008

This lens can be used for many other photographic projects besides just landscape/scenic panoramas. Of course, some caution is needed when thinking about the lines, convergence, etc...but it is a fun as well as useful lens. It goes with me everywhere! Admittedly, it's not my "primary" lens...that'd be my Pentax SMC 18-250mm lens.

Impressive

23 October 2008

I purchased this to play with both the wide angle capabilities and the fish-eye views this creates with my K10D. The pictures thus far (roughly 100-120) have shown excellent quality. The types of pictures I've been able to take by purchasing this have impressed me!

The only issue I have seen is the images are dark when the sun is in the picture - which is easy to do when the sun is high in the sky. At 180 degrees of view, it captures a lot. Like with anything, one simply needs to check the shot before taking the picture and use the right lens for the situation.
