the updated kit - today's version :^)

A week after speculating on missing gear I have a 15mm. A month after seeking and finding a 35-70 lens for my manual-focus kit I have my favorite 28-105 again. When does it end? Obviously about two weeks after I'm dead, since I could go suddenly after placing a bid.

 So am I happy? Well, I'm a naturally happy guy so that doesn't quite fit - but I am satisfied, which is the equivalent in gear-lust terms.  The lenses in my possession only lacks a super-zoom and for now that's OK; the K-5 is a camera that still leaves too little missing to cause me any concern.

  •  Today's AF kit: Sigma EX15, Pentax DA18-55, EX/DG50 macro, DA55-300. 
  • The MF lightweight kit: Rikenon 28P, 35-70P, 70-150XR. 
  • The MF 2-lens (or video) kit: Vivitar(Kobori) 28-105 and 70-150XR. 
  • The alternate kit: Lumix G1, 14-42 and 45-200 OIS zooms.
  • The full-frame-sensor kit? 15, 28, 50 primes, 28-105 and 70-150 zooms!
Good stuff all, and plenty of time to learn it all (assuming  I do not go suddenly!).  And now the film bodies, which now consists of two Pentax MEs and two Ricohs (XR-10 and KR5 super).  The Vivitar 28-105 came with a leather-wrapped ME 'SE', a special edition with diagonal split-image focusing screen.  Pretty cool, and now my lead body for the rare use of film.  I really want to learn more about the XR-10 that came with the 35-70 Rikenon though, it shows some interesting features from the early days of electronic cameras.  I need to download a manual so I can brush up, and to figure out what the button near the lens-mount does!

more coming soon ..

Why I like the DA 55300.. and the Rikenon 70-150

This image was taken with the DA 55-300mm lens (150mm f/5 -1/250s, iso3200). It was also shot with the Rikenon-XR 70-150 (150mm, f/4 -1/125s, iso1600). They are shown below - though not necessarily in that order.

  •  The Rikenon was focused through the VF, so no precise live-view focusing aid. It was also taken in Av mode so exposure was set with the wide-open lens. SR was set at 150mm. 
  •  The DA lens focused itself and found f/5 to be its wide-open choice. It also was in Av mode.  

These were not shot as controlled images and I could have done much better for making them both sharper and closer to identical (e.g. fixed ISO and a tripod). They are also substantially cropped to show the area of most-critical detail; crops were in the same portion of the image field, I didn't cheat and put one on the frame's edge!  So they are not intended to be rigorous, simply what-if one-off hand-held shots to see how they compared. Aren't hyphens fun?  Let's face it: I do not spend my life going around taking test shots; I will grab the camera and get the shot on the fly, and that's what I want to test.  Both used center-weight metering so that matched well - though at f/5 vs f/4 I expected the DA image to be a bit darker.

Given all that, I can only say they compare quite well. In both cases, great isolation on the lonely seed-case, nice background blur, and decent branch detail. A slight color shift, no surprise even with flat grey lighting, as 20 years has seen great changes in lens coatings. Hard to pretend you cannot see which image is which; ISO3200 is great with the K-5 but it isn't an invisible process.
