Pentax K7 - Sigma 100-300mm f/4 APO EX DG


Pentax K5IIs - Sigma 100-300mm f/4 APO EX DG.





Unfortunately the ginger colour of my beard stands out though, I just dunk my face in some mud, it does wonders for the complexion and the upshot is it makes me practically invisible.

This is one of the biggest gripes I have with the FA*250-600mm, but at least the tripod foot is not as flimsy as the current Nikkor AF-S 200-500mm f/5.6E VR. With my FA*250-600mm I use a gimbal head [Kirk King cobra] but the point of balance is still too forward, and it puts the controls for focus and zooming at uncomfortable angles. Canon and Nikon put the controls for focus and zoom forwards while Pentax is the opposite, I have no idea why the did that. I do own a full wimberly Gimbal tripod head but due to the design of the FA*250-600mm, I cannot use it.

The thing is with the FA*250-600mm, particularly on APS-C you need some pretty hefty support hardware to get high quality results from the lens. Or use wireless flash to freeze motion which is something I have done with long lens wildlife photography before.

I have had the Sigma 100-300mm f/4 APO EX DG for a number of years and it is an extremely capable lens, albeit difficult to find due in no small part to the excellent optical qualities is has.

Over the years my one main gripe with it is the lack of a focus limiter, which means hunting can be an issue on camera bodies with slower AF like the K10D, but on the KP and K-1 AF speed is quite fast and accurate.

Talk about a rough start to life.

I'll have to get my FA*250-600mm f/5.6 out - being in isolation for so long, I haven't had much of a use for it.

I use a Mad Catz RAT7 Mouse, possibly one of the most customizable and ergonomic computer mice I have ever worked with...I'll admit it looks really uncomfortable but it can be configured fit the individuals requirements.



For working on photos on my PC/laptop I work with a Wacom Intuos pen tablet, you can get models with touch sensitivity however I find that pen input is perfectly satisfactory.

I am rather neurotic* about certain things dust is a particularly annoying thing I have to deal with, but glass cleaning** is something you simply cannot cut corners on. I used to live on a beachfront property and keeping those windows clean especially after a big storm hit was a neverending task. If I ever buy a house I'll look into getting that fluorine coating Pentax is using on their glass so nothing sticks to my windows...ever.


* I'm also a bit lazy, so I try to do things as efficiently and effectively as possible so I don't have to do them again.

**knife sharpening is another thing i'm very particular about.

Which leads to another essential skill: learning you cut your own matte boards. I send my prints to the framer with museum grade matte boards and foamcore backing behind each print, I use archival tape to hold each image in place along the top edge - paper will buckle and shift with humidity so I allow for some movement to prevent serious damage to the print by not attempting to hold the image rigidly in place.

It is difficult, but not impossible. My colour vision has a rather unusual defect that turns out to be beneficial when it comes to hue discrimination even with colour negatives. With time you can train your eyes to ignore the base colour, and further practice and training (and a few tricks) you can learn how much colour correction needs to be applied without wasting much paper. Of course the blowback from this training and practice with negatives is in my early days of making cibachrome* prints led to some interesting looking prints.




Those poor bastards were driving their cameras into the dirt ripping through film like cheap christmas paper, on average they would be shooting well over 20,000 frames a year which is a massive amount of film. NG demanded transparencies because they were easier to look at and easier to print.




I hear you. The reaction of first time darkroom students observing the image forming for the first time is something I partake in when I assist in my photography school's darkroom classes.


*thankfully I never made those mistakes when I later moved on to the more intensive (and expensive) Dye transfer technique.

I own the Zeiss T*8X20 Model and I find it very useful and compact, though difficult to focus one-handed as the rear eyepiece rotates and keeping a grip on the whole thing while focusing is tricky.


Optically it is decent for an achromat, the plastic construction is a bit disappointing considering the price point.

In some ways printing in the darkroom was easier, even colour balancing a negative print is easier as you can clearly see the result of the selected filtration on the easel.

After a few years of mucking around with printers up until 2014 at which point: I gave up and I outsource my printing*, I think printing is very much at a technologically immature stage. There are too many different systems that interact in disparate ways and it is all to easy for the wrong check box to be filled for it to all go horribly wrong. There are a large number of photographers whom never stepped into a darkroom, notable examples being HCB, Sabastio Salgado, and Vivian Maier. Though it is hard to find people who *get* your work and understand what you want. I send colour profiles of my monitor to the guys that do my printing [though owning an industry standard** Eizo monitor makes this somewhat redundant ] So they can at least see what i'm seeing. I get my profiles from paper manufacturers and I only work with three different papers, all are fiber based : baryta flat matte, a Baryta Semi-matte and Baryta full gloss paper*** : that's it. When it comes to printing: I see the KISS principle as more of a hard rule. If it works for you: Do it. Don't follow some convoluted logic that isn't your own because of some obtuse concept of how you ought to be doing things - that is often a sure fire path to failure (and a lot of wasted money).


Though there are some specialized processes whereby I get my Monochrome photos printed, and that is through piezography although current printers are very good at B&W, I find the depth and tones introduced by multiple layers of inks to be unmatched. And the practical upshot of the piezography process is that the longevity of the image is enhanced. IF I had to start printing my own works, I'd start with a Piezography CIS modified printer and save myself the annoyance of colour management altogether.


* After I send off the files to my clients, I leave the printing to them.
** Though just because these monitors are common doesn't mean they don't experience colour shifts over time.
*** you'll note I like Baryta based papers, there is a very good reason for this as baryta is a very consistent white. Some papers will shift one way or the other over time I find that baryta is inert enough that this is a non-issue.

The Human cost would be too high. I suspect that CoViD-19, in a similar fashion to the Black Death will leave its marks on humanity. The number of people who survived the black death was incredibly low..but those who did enjoyed a better diet and more resources as the plague happened to kill off those who were old or already ill.

Scholars debate over the exact percentage that were killed by the Black Death, but we can all agree it killed a gargantuan* swath of Europe's population, I don't think the two world wars combined killed so many people.

*we are afforded so few opportunities to use that word in a sentence.

Having an incredibly short MFD can be a bit of a hazard on an ultra-wide lens, the front element being so close to the subject that there is a potential for damage. I would rather have a faster lens than the novelty of a short MFD.

Same goes for photos, but that is beside the point. I still carry around 16X20 portfolios. I find clients respond differently and are more engaged with the physicality of handling prints. Of course each portfolio is a costly thing to produce $500 for a custom made leather bound and Box covered portfolio from a bookmaker...IMO it is worth it. Even if it is for personal work, it is most gratifying to go to my bookcase and see what I was doing in 2011.
