35mm f2.4 for Leica
Posted By THoog

Well, the first thing you should have thought of :) is the Carl Zeiss Jena Flektogon 35/2.4, which has been around since at least the 1970s (I'm not entirely sure when CZJ switched from 35/2.8 to 35/2.4). In optical design, the IBERIT is closer to the Flek - 6 elements in 6 groups - than either the Pentax (6 in 5) or Leica (6 in 4). If, as they claim, their optics are designed in Germany, I'd think they would look for inspiration at home, rather than Japan.

Handevision's IBERIT lenses are all f/2.4, which mimics Leica's Summarit-M lenses, also all f/2.4 (IBERIT: 24/35/50/75/90mm, Summarit-M: 35/50/75/90mm).

I included the K-50 in my list of bodies that could use AAs with the adapter clip: "K-r/30/50/500".

Coming into the conversation late, and the point is moot if you don't like AAs, but since the Internet is forever and others may be reading: the K-S1 doesn't use AA batteries. It uses the same D-Li109 battery as the K-S2. The K-x was the last Pentax body to only use AAs; the K-r/30/50/500 used the D-Li109 or AAs with an adapter clip, and higher-end bodies with a grip.

My K-S1 comes closer to my K-x in small size and handiness than anything else I've tried, but the odd grip and looks put off a lot of people. The K-S2 is a better value, having more features in a package almost as small as the K-x, but a little heavier (if size is a concern).

I will say that the 20MP sensor in the K-S1/S2 comes closer to the "look" of the 12MP in my K-x than the 16MP or 24MP sensors. In my opinion, in low light, the 16MP sensor in the K-5 (and others) has the edge over the earlier 24MP (K-3,K-3II) or the 20MP, but the newest versions of the 24MP in the K-70 and KP are hard to beat.

Yongnuo 14mm f2.8 Auto-focus Lens

To be honest, they have only recently made ONE flash for Pentax, and while the YN585EX is a decent cheap basic P-TTL flash, I don't think I've seen any discussion of it that didn't revolve around the lack of features like HSS and radio-sync, which will probably mean low enough sales that they won't bother with a higher-end model. :( The vast majority of their flashes used on Pentax are center-pin manuals, about equivalent to T-mount MF lenses that could be used on K-mount, but weren't specifically designed for it.

But who knows? Yongnuo will go where the (low-budget, consumer grade) money is. I just wouldn't expect a lot when the most expensive lens in the series is less than US$200.

Various Sigma 30mm F1.4 Lens

It depends on what your priorities are for IQ. To recap what I said in my review of the Art 30, the EX 30 has a strongly curved plane of focus, which gives VERY soft corners, but this can be used artistically for subject isolation (some dismiss the lens completely because of the corners - it seems to be a lens you either love or hate). The Art 30 has more correction and more usable corners, making it IMO a better general-purpose lens. The Art 30 seems to have a little more background blur at any given aperture. The EX 30 gives nice "stars" at smaller apertures, while the Art 30 has very strong flare control and won't "star" even if you want it to. Depending on how much you have to stop down to get acceptable sharpness, the DA 35/2.4 or FA 35/2 may actually be viable options, especially if budget is your top priority.

Front/back focus adjust doesn't do anything for the focus issues on the Art 30. It either focuses correctly, or AF dithers and (sometimes) just gives up. For what it's worth, my KP has no problems with my copy, while my K-30 and K-5II could only use it in center-point or select-point mode.

Oddly enough, of all the Pentax bodies I've used over the years, the K-30 and the *ist-D were the only ones where my hand hurt after a prolonged shoot. Something about the shape (not size) of the grips, I guess. For the KP, I use the "small" grip for small primes like the DA Limiteds, but anything bigger than that feels better with the "medium" grip; for larger lenses like the DA*300 or DA*60-250, I switch to the "large" grip.

Is Nikon Canon and Minolta doing the TTL to P-TTL change

You should switch to a Minolta. I can absolutely, positively, 100% guarantee that they won't ever change their flash technology.

(Minolta stopped making cameras 11 years ago, by the way.)

Seriously, every brand has changed their flash metering technologies multiple times over the years - Pentax is the LEAST likely to make changes. Usually, the complaints are that Pentax has not changed enough.

My K01 gets hot

It's normal for the K-01 to get noticeably warm on the grip end. It's due to the large battery, the electronics being crowded together on one end, and the aluminum frame acting as a heat sink.

The PLM is the only KAF4 lens so far. The 18-50 is KAF3; this can be confirmed on the review page both in the specs and the pictures of the lens.

It wasn't "good enough" for 2012, so no. I own several K-01s, and I personally like the camera a lot, but it was very unpopular, even in 2012. I have seen a lot of people buy the K-01 for the low price, and then get frustrated at its limitations.

You haven't said what you want to use the camera for. The IQ is excellent, the shutter fairly quiet, and focus peaking is useful for manual focus lenses. With short, fast primes, the K-01 can be a lot of fun - it is a different experience from a DSLR or an EVF mirrorless. With longer, slower autofocus zooms, it is painfully frustrating. For shooting moving kids or pets indoors in low light, it's almost useless. I personally never had much of a problem shooting outdoors in bright sunlight, but that is a very common complaint.

The K-01 can be handy as a second body, especially with just a wrist strap - I find that getting away from the viewfinder and shooting at arm's length makes me more likely to try shots that I wouldn't bother with a DSLR. But as your only camera, you really have to consider what kind of shooting you will be doing with it.

In the US, yes, but not in some other markets, Australia in particular.

The grips are more than "a small piece of plastic", but Au$70 does seem a very high price.

I use the large grip with bigger lenses (DA*60-250, DA*300), and medium most other times. For a small prime like the DA Limiteds, I'll go with the small grip just because it feels more "old school".

The DA 10-17 not only shared its optical design with the Tokina, the petal hood is also threaded in the same manner. It's been some years, but IIRC, I screwed a 58mm step ring onto mine to see if it fit, and it did.

Agreed, it has an adapter ring mounted (I own a copy of the Spiratone Tc 200. It's a T-mount.). That adapter looks much too thick to be a T2-M42 adapter - an M42 adapter would only be as thick as the knurled part. It must be for some other type of screw mount.

Yeah, I get similar search spikes for anything with "feet" in the caption. I have mixed feelings about the fake followers - on the one hand, there's a certain justice to honey traps aimed at people who use flickr for their smut instead of perfectly good smut sites. On the other hand, this is why we can't have nice things. :( The Internet was fun, but it's time to shut it all down and go back to.. um... have they found any Sumerian clay tablets about Nigerian princes needing help with transferring gold out of the country?

I think the problem is using the PF insert image button. That is adding extra tags for a link to an image, when the BBCode coming from flickr already has everything you need. Just copy and paste the BBcode from flickr directly into your post, without using the insert image button.

Emil Busch Glaukar 3.1 price?

It's not really significant for this kind of lens. They've only sold 178 lenses so far - the minimum number for a particular mount is probably... ten? Five? At two thousand bucks a pop, they probably would make it in any mount you wanted. All they have to do is cut the rear tube to length and add a mount plate with appropriate bayonet lugs. No linkages, no electronics, nothing.



Fine - make it a Spiratone / Sankor 105/2.5. (Which isn't an awful lens, if you are into M42 presets.) :D

Those are various pre-order "pledge" levels. Because it's a Kickstarter project, supporters can pledge various amounts, with "rewards" (lower serial number, earlier delivery) for higher amounts. There are a fixed number of slots for each amount. The lowest levels are all full, so the minimum acceptable pledge is currently $799. HOWEVER, if you wait until the lens is in production, it says this:

This lens will practically be handmade piece by piece in the future. Therefore and due to the amount of manual work that has to be done it will sell for a retail price of approximately $2.000,--, strictly online to avoid all overhead costs.

As to how does it compare to an SMC A 100/2.8, a better comparison might be a K-series 105/2.8, or even a Super Takumar 105/2.8. The Glaukar will only have a K-mount bayonet, and no aperture arm or A-contacts.

I didn't see anything in the sample photos that was worth four times the average going price of the above lenses, much less ten times. If you have money to burn and are really, really into antique lens designs...

I have a couple hundred followers on flickr. It's never occurred to me to look at (or care about) what's on their profiles - I just figure they are bookmarking me because they saw something they liked, and it's easier than favorite-ing multiple photos. I wouldn't consider it an intrusion unless they started pestering me through comments or email. No one has ever asked me to follow or favorite in return.

The only people I've ever blocked on flickr wanted to start a political debate in the comments on a couple museum photos.

If I didn't want my pictures to be viewable by the general public, I would set the "who can view" permission to Friends and/or Family - but then I'd have to maintain those lists and convince my friends and family to get flickr accounts just to view my pix.

You and I know that, but after the K-1 came out, there were at least a few people on PF questioning whether Pentax still needed to bother with APS-C, now that they had finally made the move to 35mm full frame. If they exist here, they could exist at Ricoh.
