On article Samyang teases 'summer blockbuster' lens announcements (123 comments in total)

They have some fine lens designs. Is it true that the only AF lenses they'll make are FE mount because Sony is the only OEM that freely publish their mount spec? Therefore Samyang doesn't have to reverse engineer Sony AF parameters?

McBrian: Haven't read all the posts so forgive it's been mentioned already.

The exif for the AF tests currently posted show SR was on, was the camera tripod mounted? It has always been the case that SR should be switched off when mounted on a fixed support although the K1 manual does not specifically mention this, but it does state that SR is automatically switched off when using remote or self timer so it's logical to deduce that SR should be off when mounted on a tripod.

Joergensmi: This is certainly easy to imagine. The SR improves with each generation as well. I remember all those posts when Nikon D800 & Nikkor 85mm f/1.8 first came out everyone said they have to have 2 X 1/fl to hand hold it on that huge sensor. No such comments with the K1, some have said they get sharp hand held shots down to 1/2 sec when hand holding a 50mm lens.

I took it that way. There was a discussion on the forum a while back about whether leaving SR on when on the tripod makes a difference. YMMV, but when long heavy lenses are involved some posters thought leaving SR on helped since the big lens still can vibrate a bit. For landscapes from a tripod I'd say SR off but I have no certain proof since I've forgotten to turn it off before and didn't really notice that hurt IQ. It is probably just a good habit to turn it off. Also during panning SR would shut off on older models. K1 might adapt (OS mode 2 style) nowadays though.

Professor999: (cont.)
So, the titles all seems very positive or in the case of 'X Camera Review', neutral.
Strangely, the latest Fujifilm First Impressions published AFTER the Pentax K1 Review has a question mark in the title.
A cynical person would say that the writers have included it to say, "Look, we don't just do it for Pentax". Based on the other titles from this year's reviews maybe the cynical person would have a point.

So what would be wrong with changing a couple titles to: 'Setting New Standards?' for the D5 or 'Back To The Action?' for the D500. Then we could re-read the respective reviews with an ironic voice in our heads. :^) I guess I get your point.

asp1880: This AF-C discussion ought to be winding down by now. So perhaps I shouldn't be posting this then...
Anyway - two things:
1. I trust the DPR AF-C test. Its results on the Pentax cameras mirror my own experiences very well. My own K-3 also usually adjusts the focus only every second or third exposure in an AF-C burst. And I've shot a good amount of competitive bike racing with it.
2. The Pentax system is actually capable of shooting AF-C sequences where it adjusts the focus for every shot, even at closer range. I've seen this a number of times. But it's rare.

@DuncanM1: Is there a link to the Chasseur D'Images review? I realize it could be only in print.

@ Simon: His second paragraph tells it.

hikerdoc: Hell hath no fury like a pentaxian disappointed. I would venture to guess that had the AF been able to challenge the efficiency of Canon or Nikon there would be none of this questioning of test methods or bias.

A lot of posts for 12 users. Breakdown:

Pentax still makes cameras? : 240

In reply to:

minzaw: ?? definition of Limited lens???

I'll give it a try:
It is a marketing term started around year 2000 by then Pentax corp. It is probably intended to imply a limited release item of high build quality. They have about 9 or 10 models now. All the early FF ones were certainly of high build quality. With FA 31 ltd. being about the highest build quality lens anyone would ever be likely to set eyes on. Look up Jun Hirakawa, designer of FA 43 & FA 77 ltd., to get some of his lens design philosophy. That's the 'not much' I know about it. I have owned the FA 43 and love adapting it to a Sony cam.

In reply to:

Professor999: Limited lens selection?
The new lenses cover a range from 15-450mm
many at F2.8.
If anybody has LBA there are a wealth of 'older' lenses such as the 31, 48 & 77mm.
How many lenses does one actually need?
Considering the camera has just been released & has Pro level lenses covering 15-450mm, I'm curious as to the wording 'limited'.

@ Tailings:
'"Limited", as in the FA 77/1.8 Limited, is nothing more than a marketing buzzword. And a poorly defined and chosen buzzword too, IMO.'

FA 43 & FA 77 are smaller than one would expect based on modern Sigma & Tamron designs. FA 31 is more mid sized. btw, FA 77 ltd. was voted best Pentax lens ever made, I think. I have never owned a copy but it must be a pretty good FF lens in general & I would expect it is 'up to the task' of a K1 camera. The badly off centered copy DPR had a while back not withstanding.

Current list of capable FF lenses (Pentax Brand Only) 15-30/2.8, 24-70/2.8 31/1.8, 35/2, 43/1.9, 50/1.4, 77/1.8, 100/2.8, 70-200/2.8, 200/2.8, 300/4, 150-450/5.6, 560/5.6
Rokinon: 14/2.8, 24/1.4, 35/1.4, 50/1.4, 85/1.4 (excellent), 100/2.8, 135/2 (excellent)

Professor999: Could the 'Special K?' be removed from the title-
It doesn't add any useful information & 'Pentax K-1 Review, in my humble opinion, seems more professional.

I agree. The title is the most important. Sometimes I only read titles and boilerplate (invent) the rest from my memory of the source. It is the same as outcome bias in testing, which many seem to think exists here.

I'd have to become capable of removing my own bias to prove it though. :^)

Joe Ogiba: The PENTAX K-70 employs PENTAX's first Hybrid AF system during Live View autofocus operation. By positioning a contrast-detection AF sensor with superior focusing accuracy and a phase-matching AF sensor on the image sensor's surface, this innovative hybrid system optimizes the benefits of both AF systems to assure high-speed, pinpoint AF focusing on the subject.

Get the K-70 if you want the best AF in a Pentax DSLR. If the K-1 had that and 4K UHD like many other cameras it would be a killer camera at that price.

Don't know about that. K-70 hasn't hit the streets yet.

Petroglyph: Just came back from a set and this is still going on? 3-range focus limiter on the DFA* 70-200 was set to what value for the focus test? Thanks guys.

Thank you, Rishi. I'm not likely to get my hands on a copy of the lens any time soon, but if I do, I'll try to replicate the test. I remember a Canon lens, and I can't put my finder on the model, that had real trouble (slowed down) crossing a focus limiter boundary during af/c. Usually, those are toward the mfd side and limit toward infinity. But this 70-200 lens has 3-ranges and the middle range might be out where the cycle is. As I said, I don't have a copy in hand.

kobakokh: and: warranty of shutter is 300000... This is one of the basic advantage of K1 against any other cameras... Is it?

It is 300000 mabf. Mean = average actuations until failure. Yes, that is a lot better than most.

Remember the Nikon D800/800E that got a 35 page review complete with instructions about how to set up all the menu items & what they do? A camera that had (known later) PDAF issues at the time. No wifi, no Pix shift, no 87 weather seals, no astro tracker, no GPS, no TaV, no tilt screen, no function lighting, no focus peaking, no adjustable brightness on the LCD screen, it did have USB-3, cough, what's up with that Pentax? You have USB-3 on the aps/c cams. Anyway, a fuzzy blow up of a soccer player's face 'proved' it could do AF tracking. D800/800E (3300$) conclusion:

82% Gold Award.

I doubt they could do it at the same price though.

norman shearer: Reading all the contradictory comments about AF reminds me of the UK referendum - you just don't know what to believe. I suppose it is all comparative and those that have experienced much better AF are not afraid to say so. However I do wonder if Pentax defaults are partly to blame and user inexperience also?
Whatever, it seems clear that if Pentax could up their game with AF then they could wipe the floor with the competition. So hopefully Pentax are listening and prioritize AF development for the K2.

I agree about the default settings. Ricoh has a definite idea of what type of photography the camera is intended. How about they send out some information to users about how to set the AF up for various scenarios? I didn't just hire a Canon 7DII and immediately know how to set up User 2 for BIF & User 3 for football. I had to do some research and dig into the menus. Ask questions on the forum.
