BTW, the DA*55mm is now going for $629 at McBain - not quite as enticing a price but still not bad...

Do plane tickets count as photo "accessories"? Cause they really do help with your shooting...! And what about classes? Cause if I had $5k floating around, I'd rather travel, either on my own to, say, an eco-lodge in Costa-Rica, or to attend something like Bugshot. A more appropriate question for me would be: if you had a $5k budget to improve your photography, how would you spend it? Then we'd see how many people are gear-centric...

But for the current (Pentax) gear wish-list. Let's see...
  • K3ii or KP to replace my aging K-3 ( ~$870)

  • Laowa 100mm 2X macro (pricing should be announced shortly, but let's budget $750)

  • Laowa 15mm Macro ($500)

  • DA 300mm ($1k?)

  • SMC DA 15mm ($300 used)

That's only about $3.5k, right?

Maybes, if I had to spend the whole thing on gear:
  • DA 55mm

  • 16-85mm

And a oh-what-the-heck:
  • Pentax-A 50mm F/1.2 or a good used 55mm F/1.2, maybe a converted Canon FL 55mm F/1.2 from DCShooter.

But I think I'd rather spend only up to $3.5k on photo gear and then keep at least $1.5k for a trip to an eco-lodge in a place like Costa Rica so I have nice things to shoot with all that gear.


Actually, now that I think about it, if I knew I could spend on travel, I could make do with just a new body, a 16-85mm (to have a sealed walkaround for Costa Rica) and maybe a DA 300mm if I need something long...



Wishful thinking:
  • Bring on the K-3iii instead of K-3ii or KP!

IMHO, the algorithm's definition of "interestingness" is based almost solely on engagement - the reactions your shot generates. I don't think it looks very much if at all at the content/composition/light/whatever of the shot itself. It's also, I think, heavily geared to the speed of the reaction of your network/groups. So getting some likes & comments very quickly is a good hint a shot might get picked...

My shot above has now been dropped, BTW.

Thanks guys! I enjoy your shots too! (WP, that spider focus stack was/is just mind-blowing.)



:D

When the Raynox is on the D-FA 100mm, moving the focus ring changes the magnification of the shot, so you can't twist the focus ring to move focus point in the traditional manner. What I do is pick a magnification using the focus ring, set the camera to Continuous High shooting, and then to attempt a focus stack, I brace as well as I can and fire a volley while moving the camera slowly backwards. (I move backwards just because Zerene likes to stack from back to front.) With the Godox V850ii flash I am using, flash power varies from about 1/16th to 1/32nd, and at those powers, the flash can keep up with the K-3's 8.3fps for around 8-15 frames without missing a beat. (I also sometimes use a Godox AD180, which is about twice as powerful and has a huge external battery, but it's heavy and cumbersome.) The toughest part is moving slowly enough to not have gaps between the in-focus areas from shot to shot. Frankly, I could use 10-12 fps, but I'm not sure the V850ii could keep up (though the AD180 wouldn't break a sweat). IMHO, Zerene is quite amazing for it's ability to align the shots and correct for my never-perfectly-linear movement, and I'm getting better at using its retouching tool when the software doesn't quite get it right.


This fly was very cooperative, so I shot about 100 frames, varying magnification and angle. Probably at least 20 different compositions, some single frames, and some stack attempts. When you've never shot a species - as was the case here - it's hard (for me) to predict the angles that work. It's also (for me) difficult to predict which angles will produce a nice background. So my approach is pretty much to try as many things as I can. :o (BTW, a single frame can tell me whether to attempt a stack or not from a given angle. It can also mean I have something for my efforts if the bug decides to leave. Some bugs don't mind a single flash, but are much less happy with 8.3fps flash bursts.)

In the end I stacked five bursts, and also considered 5-6 single frames with in-focus eye(s), and this stack was the clear winner, IMHO, for it's low angle, nice bokeh and head-on-the-left-ness (many of my shots were from the other side, with the head on the right of the frame). There's some other pretty good ones, so I might still publish one or two of the single frames or another stack, but I'm a little short on time, and this is surely not a previously unknown species, so maybe not...

p.s.: If I could improve one thing, I would make a better diffuser: one that would "droop" down on each side of the lens. Fill those shadows just a bit more...

Haven't been shooting much in the last few weeks, but I made it out to the Montreal Botanical Garden yesterday. Here's the keeper of the day. Anyone got a clue on species? Someone suggested it's a Fruit Fly on Flickr, but the legs seem too long for that, no? Given where I found it and its posture, I'd almost guess Dolichopodidae, but that would make it a non-green Long-Legged Green Fly... :o

Light, Wide, Macro & Cheap: System Options?
Posted By Doundounba
Replies: 15
Views: 1,202
Bumping this old thread to see if anyone else has anything to add...

For myself, we're leaving soon for a long-ish tour of Scotland by bike and I've decided to... not shoot macro on a bike tour (for now)! I've ordered a (used) Panasonix LX10 and will move from carrying 2kg+ of photo gear to under 500g, at least for the next trip, which will be our first extended bike touring adventure. I'm also giving up (for now) any kind of weather sealing and having easy access to a FoV wider than 24mm, though the LX10 has in-body panorama, so maybe that last one won't be a problem...

I might come back to this issue if we go through with a plan for a 3-month long tour next year.

I was put off by the need to invest around $2k no matter which system I choose to get back to where I am now in K-mount, except lighter. I also feel like I don't want to leave K-mount, but would need to sell all/most of my K-mount equipment to justify spending that much money on a new system. I don't think I'd regret switching eventually, but there's an emotional attachment to the k-mount, for whatever reason, and I can't justify having two entire systems...


FWIW, in the end the main contenders were:
  • Canon M5 or M50 // Canon 11-22mm // EF-EOS M Adapter + Tokina 100mm Macro (or similar):
    A very nice combo, with the possibility to add the MP-E when not cycling, and the possibility to expand into the Canon EF line in the future. But nothing is WR here. And with an M5 mark II rumored to be coming at Photokina, it seems like the wrong time to invest into this ecosystem. If Canon does bring out this new body (and it's competitive) plus the rumored fast APS-C prime, maybe I will make a system switch to Canon...

  • Panasonic G85 or Olympus E-M10iii // Olympus 9-18mm // Olympus 60mm Macro:
    Again, very nice combo. I did find the G85 to be a tad expensive for a 16MP body, the M10iii is not weather sealed. The 12-60mm Panasonic is a real nice kit lens, and sealed, for $100. Could possibly live with just that and a macro... The 9-18mm seems very expensive for what it is, though there are sales and you might find a good deal used. And if you want to get the 20MP m4/3 sensor, you need to go up from the G85 to the GX9, and you give up weather sealing and battery capacity. And the G9/M1ii are waaaay too expensive and large. Give me a G85 with 20MP sensor, and I might make a system switch to m4/3s...

I guess I'll re-evaluate again in the fall, after Photokina and our trip to Scotland. For now, soldiering on with the K-3 when not traveling, and cycling with the 1"-sensored LX10 is what it will be...

It seems a little frustrating to me that many of the winning shots are not actual macros. They should call it "an eye for details" or some such vague expression that leaves a lot of room for interpretation...

Focus Stacking

No Pentax body does either focus stacking or bracketing. I believe many Olympus and some Panasonic bodies do both. Panasonic also has something they call "post-focus" in either 4K or 8K photo modes, depending on the body. I think the Nikon D850 has focus bracketing.

That being said, I find the K-3 to be a pretty decent body to shoot handheld focus stacks. I use a li-ion flash (Godox V850ii or AD180) and fire volleys of shots at continuous high while slowly moving the camera. I use Zerene to stack the shots. It works half decently, if I may say so myself, and even getting a two-shot stack makes a pretty big difference in DoF for macro. (I shoot mostly in the 1:1 to 4:1 macro reproduction range, BTW.)

One of the gems of the Pentax lens line-up. Most ~100mm macros are 700g+ these days, while this one is 340g, while retaining a great build quality.

Thanks! Although I've seen mites on damselflies, they seem much more common on bumblebees - at least around here.



Thanks! But please don't let me stop you!



Thank you! Flickr seems to agree too, as The Algorithm has chosen the metallic red damsel for Explore today. :cool:



Great shot! If we were to not post photos of any species we've photographed before, most of us would rapidly run out of images! But I agree that it's nice when you run into a new species.

Haven't been shooting much lately. Thought I would shoot a lot during a recent vacation, but the incredible heat wave meant that after a day of cycling and then setting up camp (we were bike camping), I wasn't too interested in shooting, even though we were in awesome locations for nature macro...

Anyway, here are two recent shots from the around the house, reposted from Show Me Your Insects (my main hangout)...
