HD Pentax DA 35mm Macro Limited

I use this as more of a close-focusing normal lens than a macro. It is certainly sharp enough to crop if your working distance needs to be further away from your subject:

Thank you. I am just getting used to what kind of results are possible with this newly acquired Zeiss planar lens.

Irix 150mm Macro - FF or Crop?

As trailed earlier in this thread, I have been fortunate enough to get my hands on an IRIX 150mm/2.8 Macro. My earlier shots were on my K-S2.

Given that I mostly take shots of insects in the field, often at high (for film) ISO, I had wanted to try the Irix out on my K1 to see if the better sensor performance outweighed the crop factor effects.

I think I have a point of view now:
  • The greater pixel density of the K-S2 does produce sharper images, but the bokeh on FF is to die for.
  • The crop factor increases depth of field in the resulting image and increases working distance.
  • If flash is in the mix, the advantage of the K1's better dynamic range is very small. In available light, the difference becomes noticeable at about ISO640.
  • The heavier K1 balances better with the Irix. The overall weight of the K1/Irix combo is not an issue.
.
On a warm day, when the insects are buzzing, you need all the distance you can get and all the sharpness / pixel density possible to crop the resulting image. The reality is that field work on skittish subjects will be shot from up to a metre away. I'm not even sure that a dedicated macro is needed, to be honest. However, wait until the end of the day when the air cools, those insects will perch stock still. You can shuffle in to 60cm or so and shoot a 3 shot stack with available light, when sensor performance comes to the fore.

By all accounts, the KP has the lead in crop sensor performance, but I don't think I'll rush off and buy one. Like everyone else, I'll wait impatiently for the new APS-C flagship.

Male Common Darter with the K-S2, ISO 400. Female with the K1, ISO 1250.

How did you find it when using it hand-held as opposed to w/tripod? I've seen reviews that said it's practically unusable hand-held for close-up macro work.

I wouldn't go so far as to say "practically unusable", but I would say that the ease of use hand-held depends on the stability of the photographer and the confidence that you have in achieving focus.

If you are pointing downhill on rough ground, trying to capture an insect that inconveniently positions itself so that you have to twist, you are going to struggle to nail and hold focus. Your stance will not be stable enough. Add in a bit of excitement, so that your breathing adds to the problem and you will miss more than you keep.

The FOV of a D-FA 100 on a crop body is the same as the Irix 150 on FF, but the depth of field is greater. Wide open, the photographer's confidence in having achieved correct focus can be very low with a large aperture FF lens.

Hesitate and the moment is gone...

The revered A* 200/4 macro is as heavy as the Irix and has the same reputation for being hard to use (the FA* is even heavier).

So, in my view - it's a question of stance, breathing and technique. I'll spend time watching and stalking, then work out an approach to get closer (very important near water!). I try to turn my own inability to hold the lens still to my advantage by shooting three-shot stacks, but perhaps most importantly, I'll accept cropping a shot from 1m or so as an alternative to missing a shot from closer in. At 225mm on a crop body, the Irix has an advantage for this.

I really cannot get consistent results when hand-holding macros. Sometimes the results are OK, but too many are lost to camera shake. So it's either on a tripod, or at least a monopod, or use flash, and sometimes both tripod/monopod & flash as I have lost many, many early AM macros to almost undetectable breezes moving a plant or spider web and blurring the subject to unacceptability.

Playing with my Olympus E1 and the Pentax DFA 100mm Macro, it's a darn good combo!

Acadians gave its common name from the appearance of its flower petals, which resemble the head of a tortoise. In fact, in Greek, chelone means "tortoise".
I personally thought it was looking as a fish head, like the archaic Bowfin or the invading species, the Snakehead.
