Re: Do you convert all crop sensor lenses to FF equivalent?

Its an f3.5 lens, that can't focus reasonably close and costs $450.

So what? It's tiny and provides similar high IQ as the 35 f/1.4.

Do you always convert all X lenses to their FF DOF equivalent aperture? That must really take all the fun out of shooting crop sensor cameras.

The reviewer mentions it's price as a con.

Anyway, I was just posting a link to an outstanding review for an X mount lens review. Next time I'll keep it to myself.

Geez, No wonder I don't post on this forum more often. The negativity is palpable.

There is no FF equivalent of aperture. 2.8 is 2.8. Read the review and you'll understand my comment.

"At the maximum relative aperture the lens doesn’t provide useful images; in order to get them you have to stop it down to about f/3.5. In the range from f/5.6 to f/8.0 the image is already fully useful but far from its frame centre quality."

Oh, sorry I see what you mean.  When the reviewer at Lenstip talks about "useful images" it has to do with their arbitrary "decency level" of 40 lpmm.  So at f/2.8 the XF 27 f/2.8, even though the center resolution reaches a very high 62 lpmm, the corner resolution fall at 36 lpmm, just below Lenstip's decency level.

I would disagree that corners being a bit soft wide open equates to images that aren't useful.  Low resolution in the center, maybe, but for many types of images like portraits or shallow DOF close-ups, the corner resolution is essentially meaningless.

Anyway, the reason I found this review interesting is because the XF 27 f/2.8 essentially equals the resolution performance of Fujifilm's best lens, the 35 f/1.4.  That's quite an achievement for a pancake lens.  I also think the form factor of lenses like the 18 f/2 and 27 f/2.8 is well-suited to smaller bodies like the X-M1 and X-A1.

An f/2.8 max aperture on APS-C is not bad at all, considering it's only one stop slower than the X100s lens and is the same as on lenses featured on high end compacts like the Ricoh GR, Coolpix A, Sigma DP2 Merrill, all of which provide superb IQ.  The price of the XF 27 f/2.8 is disappointing, but the prices for the majority of crop sensor mirrorless camera lenses from all vendors are not exactly reasonable.
