Which lenses are you missing?

We now have a very complete lens range available so not surprisingly our requests are getting very specific and narrow. For me, I'd like to see a compact 70-200 variable aperture zoom. All the current 70-200 offerings are large and heavy. The m43 Lumix 35-100 f4-f5.6 is the sort of concept I'm looking at, but upscaled to FF. I guess you could argue that the 28-200 covers this range for only a slight aperture deficit (f7.1 rather than f5.6 - 2/3 stop). But I personally would find a 70-200 would fit better with my current lens kit (14-28 plus 24-105).

I'd also like to see such a lens if for no other reason than it should be significantly cheaper than the 28-200mm. I've got the wide end covered wit 16-35mm, 20-60mm and 24-70mm.
 
Is the Sigma 17mm f/4 not wide enough?
One of my favourite focal lengths is 20/21. 17 is too close but would be a great lens for someone using a 24-xx zoom as their main lens. I don’t often need to go wider than 21, so something like the 17, but a bit wider would be a nice fit. l have been considering one of the Laowa lenses but would prefer a Sigma made lens. It seems to me like something is missing if 17 is the widest prime in the L mount group, not counting the sigma 14/1.4 which is enormous and very specialize.
 
18-50 fullframe will be tough to design small and with a very good image quality. But if someone is able to do this, this would be a very interesting zoom range.

Which weight and which aperture need this to be so that you would be willing to buy it?
My thinking is, if Panasonic can make a 20-60 FF, and Sigma can make a 18-50 aps lens, if should be possible to make a 18-50 FF. Variable aperture 2.8-4.0. I think it could be done with a 67mm filter thread and I would be ok if it was up to 700g because for me it would cover 95% of my needs and replace 2 or more lenses.

The APS-C 18-50/2.8 weights only 290g. I could image that a FF zoom 18-50 with a variable aperture would be possible to design with a limit of 500g. If it would not be over 500g, that would be a very interesting zoom also for me.

But this will be tough. Strong competition in the Sigma line-up. I have the Sigma 16-28/2.8 and really like it. It is FF, weights only 450g and has a filter size of 72mm. 2mm more on the wide end is a bigger difference than on the long end. I wonder how many peopel would choose the 16-28/2.8 because of these 2mm more on the WA and constant aperture over a FF 18-50 with variable aperture. Might also depends on price, size and weight.
 
There is already a 24-105/4.0 Are you sure you would buy a lens with only 15mm more reach or would you like to have a smaller/lighter zoom?



There is the Sigma 35/2.0 DG DN and Sigma 45/2.8 DG DN already available. Both with aperture rings.
Yes.
Had them ... want pancakes (forgot to state) ... no thanx.

Yeah, I'm feeling much the same about the 28-200. By not going to 24 I don't see it replacing my 24-105 so it'll be an additional lens. And I just feel it's a bit overpriced at £899. You can get the 70-300 for £699 now and I really can't see a good reason why the 28-200 should be more expensive; in fact, I think it should be cheaper. So, as much as I'd like the 28-200, I think I'm going to wait a while and see if prices drop. I suspect it'll take a year or though so I've got a long wait!
 
Maybe a 24-85/3.5 in the size of the new 28-200

Where can you get the 70-300 for £699? The cheapest I can find is £899.

Yes, you’re right. I was reporting a friend who is buying into L mount at present and he quoted the £699. But it seems that there are S5ii deals that give an extra £200 off with a lens purchase. That reduces it to £699.
 
I got the 70-300 for €849 (€949 and €100 cashback), which is about £730

Here in NL with had a good winter promotion. Also got €400 cashback for the S5ii. Without those cashbacks I would probably not have switched to Panasonic I guess.

I think your experience is probably shared with many others. These deals are all about grabbing market share.
 
For portrait and poeple I wish an universal lens from full body to portrait. Something like a 2.8/40-120, so exactly between the 24-70 and the 70-200.
The announced Samyang 35-150 goes into that direction, but it is quite huge and heavy. To reduce the zoom to a 3x factor and shrink the min and max focal length on both sides will also help to do this.

Basically something close to the 25-50/1.7 from Panasonic, but for full frame and to the sensor size adjusted aperture?

Yes, but just a little bit longer at the end. A 3x zoom factor is no rocket science today and 40-120 (or 20-60 for MFT) would be very useful. I expect a 2.8 zoom could be in a normal size factor, a 2.0 would be a tank in FF format…
 
A 40-120mm is a very, very specific thing to ask for and it's hard to imagine many people buying it, mainly because starting at 40mm it doesn't qualify as wide at all.

Maybe instead of a 24-105 like Panasonic, Sigma could do a 24-120 as Nikon have done in the past and that would include the whole range you're asking for plus wide angle.

But such a lens will not occur in 2.8 in a foreseeable timeframe... You see what Canon needs to do to develop a 2.8/28-105... Also a 24-120/f4 is a total different lens like a 40-120/f2.8, very different tasks to be used for. The wide angle is normally not needed for people and portrait and to include the wide angle makes such a lens much more complicated. look at the Tamron 2-2,8/35-150, there was also nobody loudly asking for and now this is one of the most praised lenses for the last 2 years...
Sigma said, they want to go new ways, let us see what they will show in the future. A 24-120/f4 is no new way at all...

That depends. If it weights only 400g and is only 10cm long, it would be a new way.

Of course, that would be nice. But with some overview about the possible technology this seems extremly unrealistic to me. It is nearly impossible to build a small lens with long zoomrange, good aperture and good quality. That is one factor too much

Best example is the new Lumix 28-200. This lens was only possible by using a slow aperture for the long end. An f4 24-120 could not be very compact by design If you stay with f4. But if you skip the wide angle part there are many more options to go compact and maybe even faster.

And again: my idea of a 40-120 2.8 is not a replacement for typical 24-105 or 24-120, it should be a competitor to the Tamron or Samyang 35-150, but smaller and more lightweight. If such a lens will be available I would buy this at once instead of the Tamron or Samyang. For portrait and people it is a great range, with the typical 24-70 and 70-200 you always have the wrong lens mounted to your body…
