Irix lenses - first impressions

@CarbonR I paid about $350 USD for my 15mm Blackstone. It was a store demo from B&H or Adorama; can't remember exactly which one now. But, the lens as received was brand new as far as I could tell. No dust, dirt, or handling marks at all. Didn't look like the lens was ever mounted. So despite the soft edges, I kept it.

It's not the best optically but it does what I need it to do. As long as you know its limitations and shoot around it, you can get some very nice pictures from it especially if you take the time to touch things up in post.

I don't use it as often as it probably deserves because much of what I photograph doesn't call for a 15mm or wider perspective. If I had to buy an ultrawide now, I'd probably purchase a Sony body first due to more choices.

Irix lenses - first impressions

Yes, I saw that article. My sample is moderately sharp in the center at f2.8 but improves greatly past f5.6. I usually shoot this lens at f8 or higher. Decentering doesn't appear to be an issue with mine. The corners are still fairly soft in relation to the rest of the image irrespective of aperture size. I think it's just the particular design of this lens to be honest and not something actually wrong.

The fact that it's used on my K1-II which has a tendency to really exacerbate lens flaws makes the edge softness even more apparent. I don't take pictures to look at corners though, just wanted to point out how my particular copy behaves.

I took the below with my K1-II and the Blackstone 15mm. Sorry for the poor image quality as I'm on my phone. You can see the full size image on my website.

My Irix15mm Blackstone is soft around the edges. It's only marginally better stopped down. It's an OK lens if you know how to work around it. Is it worth 500 bucks? No. I would have bought the Firefly if I had to pay retail. Luckily I didn't so soft edges but great build quality is a compromise I chose to accept.

After several years of ownership, I finally decided to try the astrotracer function. Taken in my back yard about an hour ago with a D-FA* 50 @ f1.4, 180 sec, ISO 400.

Apart from Pentax, I own an Olympus E-M10 mark 3. It's a dumbed down version of their Mark 2 with better AF and video specs. I bought it primarily as a travel camera due to its diminutive size. It actually takes great pictures despite the m43 sensor. Sad to see the Olympus name go, but the company's mismanagement for the past 20 years didn't leave many other outcomes.

K 100d vs k10d

I own a K-1 Mk.II, a KP, and a K10D. It's high ISO qualities aren't great, so I usually keep it at 800 or lower. However, maybe it's just me, but a properly exposed image with good light from the K10D feels more organic; dare I say film-like. I attribute it to its CCD sensor.

It's something I find aesthetically pleasing despite the camera's shortcomings, especially when compared to it's much more modern siblings.

What ND filters are the best for Irix 15mm f2.4?

Not an ND filter, but I do use a front mounted 95mm X4 CPL from Breakthrough Photography. It's pricey but works very well. No vignetting at all.

K-1II and the new HD FA 35/2

Yes, we've talked about it before. The 35 f2 is a an older lens design. My copy is usable wide open but in my opinion, soft. Not horribly soft, but noticeable especially after switching from DA* 50 f1.2. It's not fair to compare the two though. I usually use mine around f2.4 or higher, in which case is perfectly acceptable. It's a great little lens. I just wish it was weather sealed.

SR badge fell off

Nah, I think the pressure from my fingers rubbing against the badge just loosened the adhesive to the point it fell off. There's a flat area on the rubberized portion of the grip where it used to be. It still had remnants of a thin double-sided adhesive stuck to it where the badge should have been.

No big deal really; just wanted to point out to the forum that they might come off unexpectedly.

Just noticed the other day that the little SR badge on the front of my K1-II disappeared. Has it happened to anyone else? I use heavy lenses on the K1 with a grip and sometimes when holding it, my fingers end up right on the spot where that badge used to be. I guess after some time, it just fell off; never to be seen again... :hmm:

Heavy lenses are great when you're a young man. Not so much thereafter. The days of suffering over one's artistic expression is long over.

The 50* as you say is indeed a category killer.

The 70-200 DFA*, not so much. Its IQ is on par with a well centered and calibrated Tamron. I've always wondered why it's so heavy when you have a similar amount of elements.

On a side note, I used to own the plastic-barreled Tamron branded 70-200 and felt for the price, was a very good optically. The Pentax version is a hair better. The areas where the Pentax version really excels is its weatherability (used in the pouring rain once) and focus motors. Apart from that, nothing else really stands out except its heft.

With the lenses you're carrying, sounds like most of your photography is either sports or wildlife. In that case, there isn't much you can do except maybe go to MFT (micro 4/3).

For the vast majority of photography consumers this day and age though, an iPhone will suffice unless you're making big prints.

Honestly, when I'm traveling internationally with my family these days, I'm more inclined to grab my Olympus than I am my Pentax due to weight. When I know I have to take a good picture, then side and weight become secondary considerations.

Grip creaking (near IR sensor)
Posted By amstel78
Replies: 74

Sorry to dredge up an old post again but my grip creaking is getting worse. It becomes more apparent with the vertical grip attached. Theory is that when the grip is tightened down, it's flexing the bottom plate of the camera unevenly, thus compounding the issue. The creaking practically disappears if I remove the grip which is why I mentioned it.

It's really annoying when I have my heavy Pentax 70-200 mounted.

My question is this: what size JIS drivers do I need for the screws under the battery door? I've reduced the creaking somewhat using a regular Phillips by loosening two of the screws slightly, but now I'd like to try and tighten all of them including the one at the very top of the compartment. I don't want to accidentally strip the screws in the process.

And just for giggles, here's a picture of Pentax next to my Pentax.

K1 video would have been much better if mechanical shake reduction was enabled. But, the K1 is not a video camera.
