I hear Tokina are coming out with a really nice 50/1.4 for Canon

btw, why do all that writing and ten insure that people will be looking elsewhere?

Isn't the Tokina 50mm f1.4 the same rebranded lens we just got for Pentax. I see some persons suggesting that Tokina made it but I don't really know what to believe.

I believe the consensus is that Tokina licensed the optical formula from Pentax, but that they are manufacturing the lens themselves and using their own lens coatings.

I was just looking at this video from back at CP+ showing the Tokina version of the lens - interesting to note 35s into the video that there are only 4 screws against the Pentax 7 - seems to confirm that they are using their own AF motor too

I'm not sure what it confirms - maybe that the Pentax has a tighter build?
Anyway, nice catch.

On the special site they said that they had to make the 7 attachment points to deal with the torque produced by the AF motor and I can't imagine the Tokina being more robustly built, so I think it's a fair assumption that the AF motor will be less torquey in the Tokina, for whatever reason - maybe actually because of lighter materials in the Tokina? Just a thought -I'm not an engineer.

Kunzite · 07-26-2018, 08:37 AM

They're not linking the 7 screws to the torquey motor, but it's an example of the tight construction.
They're describing what they needed to do to avoid slight misalignment of the front corrective groups; the high number of screws was just something you'd see. If that's missing on the Tokina, is there any other of that stuff missing as well?
Or maybe they're really working together, and Tokina will benefit from the same improvements?

In all probability a pre-production model. The production model may have seven screws.

Kunzite · 07-26-2018, 11:51 AM

It may have seven screws, or maybe Tokina will go with a cheaper barrel.

I wonder how many Tokina will sell compared to Pentax... that would be an interesting thing to discuss. As would be a comparison between say D850 with the Tokina and a K-1 with the 50. But what do we really want, Tokina to come out with versions for Sony and others, so Imaging Resources can change their "common lens" from the Sigma 70 to something more modern.

That's a real shame... I'm quite partial to waterlilies.

1. Because images often are better than words.

And because I'm proud of this image given the effort I had to make to take it. And because the 85mm f1.4 lens or the 50mm f1.2 lens wouldn't have helped me to take this shot no matter how good or expensive those lenses are. I was on a boat, the model was in another boat, between us there were waterlilies and I couldn't get any closer to her. In one hand I had a big silver reflector pointed at the model, in the other hand I had my camera and I took the picture (I think that this image was taken at 185mm) while the boat was moving.

2. Because an image can generate more comments and someone may have a chance to win a K1 at the end of the month if there are enough comments added in threads.

I'm not sure of the relevance of these comments. Yes, there are times when a longer lens is called for; once I got away from prime lenses, I found that I was shooting more and more with lesser focal lengths. That is beside the point. There has been continual interest in the DFA 50mm f/1.4 threads for some time now, so somewhere there must be interest in a 50mm f/1.n lens ..... if nothing else it is traditional to have one. I don't have a K-1, and have no interest in getting one; even if had one, say I would enter {which I won't} the upcoming "raffle" and won, I still wouldn't be interested, but that is beside the point. Pentax is producing this and they will put it up for sale. What happens beyond that is immaterial.

I agree that DP review (Belongs to Amazon and it maybe gets kick backs from some very big Corporations) seem to have it in for Pentax but at the same time if Ricoh doesn't lift its game and get a bigger market share it will go just as Kyocera Contax with Zeiss lenses made by Cosina did. Quality is good but without volume sales Pentax will go BobSpot - View Profile - PentaxForums.com May be we should consider rescuing Pentax by world wide crowd funding if Ricoh decides to stop production.

I'm guessing you'd have to post it in the "Post Your Photos!" section, which has a "Not For Work" tag available.

Nude photography is allowed, but you need to post the image in it's own thread, as that thread would need to be labeled "Not Work Safe"

The rules as follows:
'Not Safe for Work' (or Not Work-Safe) content is permitted on the forums, but must be clearly labeled as such and not be deemed as offensive. Such content should be limited to mild nudity and may not be pornographic in nature or include actual, simulated or implied sexual activity. While the general "pubic area" may be visible, neither male or female genitalia may be visible or serve solely as the primary subject of the image. All NSFW/NWS threads are labeled in red and should only be opened if you are 18 years of age or older.

This is what Ricoh Imaging has to say on the subject:
" At first, we wanted to provide full-frame single-focus lenses with angles of view that were different from those provided by existing models, and even initiated a project in this direction. These included an 85mm F1.4 lens, which was listed on our lens roadmap. After conducting research on the types of lenses our users desired, however, the most sought-after model was a 50mm lens — a standard single-focus lens familiar to all users since the days of film photography. There were several other options, but since this was what users most wanted, there was no reason to ignore the demand. So priority was placed on the development of the HD PENTAX-D FA★50mmF1.4 SDM AW."

We can always find cases in which something else is better suited. We can always prefer something else.
