FF Lenses on Roadmap

I don't know if anyone has noticed, but they updated the lens roadmap! The D FA 28-105 has been changed to D FA 24-120!! Very cool! IMO the perfect zoom! This is from what I can tell.. I wish they labeled them like they did in the past.

Here is the older one that shows 28-105..

Edit: The Roadmap hasn't changed.. but depending on what PDF viewer you use the lines cut off in different spots. I use the Firefox browser's PDF viewer and it shows the line at around 24-120mm. This is what I see..

That is a... 16-80 in aps-c? It's what i'm used to, not the other way around!

So a fullframe version of the HD DA 16-80. Hopefully fixed aperture

I guess it won't be fixed aperture - it doesn't say it's "large diameter"

No, it is a 24mm-120mm in APS-C...

Even though it is labeled as a standard zoom, on a FF camera the range is from very wide to short tele. On APS-C it would be a normal to medium tele.

I can just see it now...so many users who cut their teeth on APS-C trying to adapt to the larger format and applying a reverse crop factor (0.67) to get a feel for equivalence. I feel their pain, I truly do. The next wave will be hundreds of inquiries about good moderately-priced long lenses (400+ mm). Wide angle shooters will be happy as clams.

I don't see anywhere on either of those where it states the focal lengths. The DFA Standard Zoom is the same on both and suggests 28mm at the widest. It's very unlikely to be fixed max aperture. Even the new 16-85, which for the price and apparent intended use, should be constant f/4, is 3.5-5.6, which I would expect the new FF standard zoom to be.

Now they just need to add a D FA 120-300mm zoom.

Look again.. there is a change to the "D FA Standard Zoom"

No they aren't labeled, and I said that in the OP.. but look at where the lines end.. they are different in the two roadmaps.

My bad.. explanation in OP.

That's good news. 24-120 is a very useful range. Many manufacturers have very good lenses in this range (e.g. Zuiko 12-60, Sony zeiss 16-80mm).
Ideally it would be F/4 or F3.5-4.5, but my guess would be F3.5-5.6.

Also, I noticed a large diameter wide zoom - finally!

I'm not seeing any change either. It looks does look different on the website but if you open the PDF and compare it to the older one there is no difference. Why it looks different on the web site I don't know. Maybe just how it renders in the browser?

I can't believe you guys.. they are different. (My bad.. explanation in OP) Are you all looking at the PDF at 100%?? If not.. you won't see the difference. I believe it is 24-120mm.

ETA:

One possibility is that they are technically the same, but the one on the website was compressed and thus lost the important detail of showing where the lines end. If you look at the PDF at 100%, you'll see that the line goes past 28 and 105.

Okay I opened the PDF at 100% and enhanced the image to show the lines more clearly.. looks to me like 24-120mm.. (ETA: I guess this detail is only showing up in the Firefox browser's PDF viewer or Firefox isn't rendering the PDF correctly)

Same here: If you open the PDF-file in the browser, the "D FA standard zoom" looks like a 24-120mm and the line for the "D FA large diameter standard zoom" extends to 22mm! But when you download the PDF and open it with the Adobe reader, everything looks like always (28-105 and 24-70).

I initially just took your word for it and did not look too closely. I just took a close look at the pdf and it is definitely no shorter than 27mm on the short end and no more than 105 at the long end.




Just in general, I would suggest configuring to not use the browser plug-in for pdf. It is sort of a kludge at best.

I think it must be the PDF viewers not showing all the detail.. I am using the Firefox browser pdf viewer which shows the lines clearly going past 28 and 105... ETA: Yep.. that is it.. I edited my above posts..
