Close-ups with a 28mm

Okay so it’s more like 43mm on an APS-C sensor, but even so.

Walked down the Lade Braes again to put a roll of 120 through my recently acquired (& repaired) Agfa Isolette V folding camera, which I’ll post about soon, but I took the K20D as well. I knew from a previous walk that the Pentax 100mm f/4 macro is just too slow to hand-hold in anything but direct sunlight, so instead of lugging my heavy tripod along I thought I’d just try getting closer with the Sigma 28mm, to mixed success.

I discovered straight away that the Sigma focuses so close that I had to take the lens hood off to void poking the subjects…

Couldn’t quite work out what to do with this.

Somebody told me that close-ups of bugs on flowers is like crack for photographers. Pretty much right.

Wouldn’t even turn to face me, how rude!

This guy was a much more amenable subject.

So there’s a few very similar shots of him that came out alright.

This would’ve been great if I’d nailed the focus fast enough.

Most of the above were shot at f/4.5, this one beneath was wide open at f/1.8 – not much depth-of-field to play with! But plenty of Camembert-smooth bokeh~

SMC Pentax-M 100mm f4 macro

I’ve had this lens for years but never really used it apart from for the odd indoors figure shot. With spring rapidly approaching there is an abundance of flowers & blossoms lining my path to the lab every morning (dissertation deadline is looming, so every day is a lab day even in the current ‘holiday’) so what better subject for macro shooting? I need to do a more scientific test comparing the performance at different apertures, but all of these were at 5.6 & I’m already getting a feeling of what this glass is capable of.

I’ve noticed a little bit of CA, but I’ll need to do more testing to see how bad it can actually get.

These were all shot on my K20D, which has a 1.54x crop sensor & I cropped this shot down quite a bit in Lightroom as well, but it still has plenty of detail.

A 100% crop of the above.

Definitely my favorite from this morning’s walk, the flower on the right is tack sharp. This one is cropped down even more than the last one, I cut out maybe as much as 40% of the frame.

Once again a 100% crop for you to peep at.
