Do I need to fill the gap between 24mm & 35mm?

Having just bought a DA12-24 & DA 35mm F2.4 I'm considering selling my DA17-70 but wondered if I need to fill the gap between 24mm & 35mm if I did sell it - do you think a 28mm is needed or is 24-35 a pretty small range anyway?

would appreciate some help on this one being used to the 17-70 for so long

thanks

Simon

I don't think so, but an FA31 would be nice to have

Just pretend like your 17-70 is gone for a while. See if you miss it.

Guess it depends on the subject matter, how close etc. Just try it without for a while and see how you get on.

I usually work with 15mm then up to 50mm without fill in lenses, but I do have a 24mm and a 28mm (shift) but seldom use 'em, or even carry 'em on a daily basis.

I'm lucky enough for my work to be able to kinda use feet to provide the fill in lenses.

No way!

Think about it this way - what different subject matter would you be shooting with this extra lens?

Need ? Not at all. 24 to 35mm is a very reasonable gap. If you need a bit longer than 24mm, you can always use the latter and crop a bit afterwards. The only reason I can see for wanting another lens is if you find the DA12-24 too bulky sometimes. As a matter of fact, that is the reason why I bought a DA21.

However, you do not mention what lenses you have to cover longer than 35mm, if any, and how often you use the 35-70mm range with the 17-70. That would, IMHO, be a more important consideration in the decision to sell the 17-70 or not.

Absolutely not. The range is very small and there is almost nothing that you cannot do with a 24 or 35 that you can with a 28mm.

I think I can live without the 28mm once I get the x100.

Shoot a 28mm lens for its own sake, not because it's between 24 and 35. I'll use various glass as walk-around-today lenses, just to savor each's character. But what's in my carry bag are 24/2 and 35/2 and nothing in between, usually. That gap really isn't significant.

Perspective!!

I'm always amazed that crop factor /angle of view / apparent 'zoom factor' are the prevalent criteria considered for lens focal length selection. I suspect that's because crop factor's the first thing you notice lookin' through the view finder.

Sure, you can get the same size of image by zooming with a zoom lens, but you can't get the same point-of-perspective without being at a particular location with a lens of a given focal length - that's unique.

Draw a simple diagram on a piece of typing paper:

a) make a 'thingy' for a target.

b) back off an inch or two an' draw a cone-of-view representing a wide angle lens.

c) back off a proportional amount (just keep it on the paper) and draw a much narrower cone-of-view for a telephoto lens covering the same target area.

d) now compare the background well behind the two views and the apparent perspective. (Remember those giant noses?)

e) now do it for real and compare the 'bokeh' in the OoF region as well.

There's a lot more to focal length selection than apparent crop/zoom factor. Same thing's true with the lens speed / number of aperture blades / bokeh presentation.

This is one of the differences between amateur and pro photos - the intentional selection of planned perspective as part of the lens selection presentation.

This is one area in which a zoom lens becomes an economical teaching tool; it takes discipline and willingness to following a planned exploration of all of the capabilities and characteristics of focal length.

Acquire lenses for the final results you want, not just to fill a gap in the millimeter sweepstakes. Then you've got some real arguments for squeezin' in that 28mm lens.

Well put pacerr!

Determine from your zoom which focal lengths fuel your creativity. If you find yourself shooting a certain focal length (and being pleased with the results), try finding a prime at that length. It should be an artistic decision (especially between those focal lengths). Perhaps you'll find that the 24 and 35 is sufficient, but that's really the only way to know.

For example, I used to only own a Sigma 17-70 macro back in my Canon days. I learned from that experience that I'm drawn to wide-angle macro @ ~20mm. From that I'm planning on making the Sigma 24 1.8 macro my next lens purchase.

Maybe you should first go out and use those lenses that you have. And yes, you need to fill it with a FA31Ltd It's the only option

It's not a gap--it's a space reserved for the 31mm ;~)

Of course another way to inform a lens-buying decision is to track the actual focal lengths used with a zoom. Others here can recommend the EXIF-reading software tools for that. Do you shoot a lot around 30? Then buy one!

Or be like me: just accumulate lots of good manual primes, and use them all from time to time. I'll admit to a favorite there, the Vivitar-Komine 28/2 Close Focus Wide Angle that cost under US$20, a superb lens. But if you want to spend hundreds of bucks for an AF prime, go for it! It's only money, hay?

Personally, I don't find a need to fill the gap between 24mm and 35mm. In fact, if I have a 24/2.8, I seldom find a need for a 35mm and go straight to a 43mm or 50mm as the next FL in the bag.

You might want to keep the 17-70 a while to see if you miss anything on it though. It does seem to plug the 50-70mm range for you
