I Miss the PENTAX Green Rings and LOGO on Lenses! >:-(

We all have learnt what Ricoh has done to Pentax recently, SMC was replaced further and the Pentax logo was removed from the name plates of the repackaged DA Limited lenses! And, a Ricoh GXR coloured red ring replaces the symbolic green rings of our Pentax DA lenses..!



Pretending Zeiss lenses? Marked "Aperture / Focal" something, instead of marking "Focal / Aperture" (which is the common convention of the industry) and particularly not "Pentax / Focal" which has been done for over twenty years for all PENTAX AF lenses since early 90s! Again, Ricoh's intention is clear, Pentax will be extinguished step-by-step and some days later this name will be removed completely and they (Ricoh) will get their final "success"! >:-o

"New" K-mount Lens Roadmap "Updated" and Published

http://www.ricoh-imaging.co.jp/japan/products/lens/images/K_Mount_Lens.pdf

Compared with the last one and the last last one, what is "new" actually? :-o

And, "2013 or Later"? 2013 has only three more months to go! And in 2046 which still means "Later"!

Maybe each year Ricoh could change the coating name from SMC to HD for some lenses and also the colours of some existing Pentax lenses can be changed (if not yet) and after twenty years they can still have their roadmap and lineup got updated each year, annually! What a GREAT PLAN and brilliant idea !! >:-{

Ricoh Continues to Dump SMC and Ricohizes the Outlook of Existing DA Lenses!

See what is just reported at the Photo Rumors (Source: Japanese Digicame Info):

http://photorumors.com/2013/08/27/pentax-to-refresh-their-hd-da-lenses-with-new-hd-coating-and-circular-apertures



The new colour scheme of the old DA lenses is just damn UGLY. The traditional blue+yellow focusing scale distance markings have disappeared! The name of HD coating is really mediocre and silly! The imitated Zeiss way of marking the lens' aperture and focal shows the lack of one's own character at all! Damn Ricoh, that's the good thing you have done and done again to destroy everything Pentax! WTF? >:-[

And, where are our new Full Frame lenses of Pentax? Any?! Why re-painting the beautiful old DA lenses and getting rid of the SMC? Do they have no better things to do but just to do evils?!?!


Last Sad News:

The Name PENTAX is Dismissed from the Cyber Space! >:-(

Shooting Moon with the Pentax Q and a F*300/4.5 K-mount Lens

Here is the result (from direct JPEG out of the Q, no major re-touching but just only resizing along with light sharpening):



( Click to Enlarge - All Rights Reserved: RiceHigh (c)2013 )

And the combo of my gear that used:



Indeed, there are quite some advantages of using the Q in shooting this type of photos, namely:

1. No mirror slap and even no shutter shock of any during the course of shooting, as electronic shutter is solely used;

2. Large magnification with higher pixel count and not much cropping is needed. The above is with effective focal length of 1680mm in 135, i.e., 300mm x 5.6;

3. Live View mode with focus peaking is especially useful for critical focusing with highest focusing accuracy that is required.

And, some techniques of mine:

1. Use spot metering and M mode, trying to expose to the Right as far as possible but avoid any highlight clipping. (As for the White Balance, AWB is just fine and will do the job);

2. Use IR remote controller to trigger the shutter (no Q camera supports the cable release) and take the shot to avoid any vibration at that very high magnification. Actually, some oscillations could be seen if the shutter release button is pressed directly;

3. Use MF focus peaking in 2X or 4X to achieve even more accurate focusing. Choose the right magnification can help even better centering of the moon. In my case, I chose 2X, as shown below:



4. Do not use very high ISO of the Q as details will lose significantly and dynamic range will be more limited. I chose ISO 250 for the best compromise of a higher shutter speed but not too high an ISO speed;

5. Stop down the lens for sharper result. The above exposure combination is f/8 and 1/125s at ISO 250, i.e, one stop faster than base ISO.

Last but not least, a very high quality K-mount prime lens like my F*300/4.5 is required. Otherwise, all those optical imperfection will appear (as they are greatly magnified with the 5.6X crop factor) before anything is recorded! :-o

The A Mount Seems to be Aborted, Will K Mount (Ricoh) Follow?



See what Sony Alpha Rumors report lately:

(SR5) First image of the new ILC-3000 (A3000 in Japan). 230K LCD and 1,44 Million dot EVF.

So, possibly this will soon mark the end of the A-mount lens line as there will be no more new A-mount body. For all those excellent Minolta A-mount lenses, the old users must use them via an adaptor and Sony will be a mirrorless brand from now on.

After all, will the Pentax K-mount get the same fate? There was a rumour about this before. In view of Ricoh has done no development of any on the K-mount lenses during these two years something, that might be possibly true, or if not Pentax the brand is to be trashed.

More K-50 and K-500 Reviews

1. A detailed mesurbation review of the K-50 with bunch of full samples:

http://www.optyczne.pl/231.1-Test_aparatu-Pentax_K-50_Wst%C4%99p.html
(in Polish)

2. Another K-500 review after the K-50 review by PF:

http://www.pentaxforums.com/reviews/pentax-k-500-review/features-and-highlights.html

But as the K-500 is just almost the same camera as the K-50, why did the review again? I really don't understand. I think most parts are meaningless as long as the K-50 has already been tested, IMHO.

(Different) Optical Constructions of the Four DA18-55 Zoom Lenses

Source: http://forum.xitek.com/thread-866434-1-1-1.html (in Simplified Chinese)

1. Original DA18-55 - 12 Elements in 9 Groups, One Aspherical Element:





2. DA18-55II - 11 Elements in 8 Groups, One ED (Extra Low Dispersion) Element:





3. DA18-55WR - 11 Elements in 8 Groups, One Aspherical Element and One ED Element:





4. DAL18-55 - 11 Elements in 8 Groups, No Aspherical nor ED Element of Any:





After all, it seems that the optical formula and construction of the DA18-55WR should be the best. On the other hand, the optical design of the DAL18-55 is a cutting corner one, which should perform worst. Not even to mention about the cutting corner build of the DAL, which adopts a plastic mount and the quick shift focus mechanism is removed altogether.

Pentax TidBits 8-19

1. DA50/1.8 is on sales, for the US users only, at $120:

http://www.pentaxwebstore.com/product/31909

Btw, is it really cheap? Just compare it with the similar offers from Canon and Nikon! One thing is for sure anyway, the original set price of $249 is just ridiculous!

2. DC Watch has reviewed the DA560, with various full samples posted, taken with a K-5IIs:

http://dc.watch.impress.co.jp/docs/review/lens_review/20130819_611192.html
(in Japanese)

I am really not impressed with the IQ of this combo. The colour rendition is terrible. Images lack contrast. The broken pixel "sharpness" of the K-5IIs images also look rather odd to my eyes.

3. A Pentax joke posted at the Pentax Forums:
